Editorial | E-Installation 1/2013

New energy and new challenges A secure and stable energy supply is a prerequisite for many companies in Germany to remain competitive and succeed economically. In a future energy mix of virtually carbon dioxide-free power generation, wind energy will play a central role in power generation in Germany. In Hall 27 of the wind international trade fair, which is taking place as part of Hannover Messe 2013, we will be presenting the complete assortment of wind equipment from Siemens, including the interaction between the components and systems. Efficient use of energy is becoming ever more important to companies. To plan specific measures for the responsible use of this resource, energy management systems are no longer just “nice to have” but a requirement for electrical power and energy tax credits. With a certified energy management system, companies can keep an eye on their own energy consumption and influence it in a targeted manner. Our Sentron measuring devices and our energy monitoring software are important components for standards-compliant energy management. To consume electrical power where it is needed, you need intelligent power distribution. With Totally Integrated Power, Siemens offers products, systems, and support for integrated and safe power distribution in infrastructure, buildings, and industry. Speaking of safety in electrical installations: did you know that Siemens has made major contributions to the development of fuses and fuse systems from the very beginning? More than 100 years of experience have allowed us to develop expertise in various special applications of fuses, such as in wind and photovoltaic systems and other DC applications. Allow us to persuade you of the value of our innovative products and services based on references in this edition of E-Installation, or talk to us at Hannover Messe. I hope you enjoy reading this issue. Sincerely,

TÜV-tested power monitoring The globally applicable standard ISO 50001 is designed to aid companies in establishing systematic energy management programs. It has been in force since April 2012 in Germany and replaces the European standard EN 16001. ISO 50001 calls for energy-related services and energy efficiency to be continuously improved and energy savings to be achieved.

detail and energy consumption to be analyzed and evaluated. These data then enable potential savings to be determined.

Keeping an eye on all the loads For the CEO of Bergmann Automotive GmbH, it was clear from the start that such a power monitoring system would need to include all points of consumption. Up to 200 meters would need to be replaced. After extensive analyzing providers for energy data acquisition systems, the company chose an energy monitoring system made up of measuring devices from the 7KM PAC series and powermanager software. At the Barsinghausen site, some 100 networked meters have now been installed. More will follow soon in order to integrate all the auxiliary loads. “That was not the cheapest solution, but it was the best one for us,” says Büthe, justifying the decision. “The digital meters had the best price/performance ratio in the market. They are very sturdy and easy to install, and they have a communication interface for Modbus TCP, Modbus RTU, Profinet, and Profibus DP, allowing them to be directly integrated into our local network.” Powermanager software monitors and archives electrical characteristics recorded by the meters, such as voltage, current, power, energy values, and frequencies. The only prerequisites are a Windows PC and a LAN network for Modbus TCP. On the PC, the power values of the monitored characteristics are shown as load curves and can be compared with 8

In order to reduce energy consumption in the face of rising energy prices, midsize and large companies in particular benefit in many ways from the introduction of an energy management system. Unnecessary energy consumption can be identified in a targeted manner, allowing further energy efficiency optimization within the company. In addition, according to ISO 50001, certified energy management systems are essential for electrical power and energy tax discounts and EEG allocations. Using standard-compliant energy management can reduce carbon dioxide emissions and help preserve the environment. The ISO 50001 energy-saving standard defines compulsory criteria for sustainable energy management for companies. To provide support for a company`s energy management system, Siemens offers the world’s first products that have been tested by TÜV Rheinland according to the DIN EN 16001 and ISO 50001 standards. The TÜV-tested 7KT and 7KM PAC measuring devices and the powermanager power monitoring software from the Sentron portfolio form the ideal technical basis for standardcompliant energy management.

The new age of electricity

Loading of a Siemens wind turbine onto the Sea Installer in the Danish port of Esbjerg

Siemens offers a wide range of products and systems that address a variety of technological challenges faced by the wind power industry. All the products feature a high degree of reliability and availability, perfect technical interaction, and often many years of experience in the field.

T

he energy revolution is under way – but questions remain. For example, how will wind be transformed into new energy that is clean, safe, and sufficient to meet requirements? Wind power is one of the most dynamic submarkets in the energy sector. Siemens is known for its innovative wind turbines, which are among the most reliable in the world. Being one of the world leaders in offshore wind turbines, the company delivered a technology package that included 80 wind turbines for the DanTysk offshore wind power plant off the North Sea island of Sylt.

A history of Siemens fuse systems

Always reliably protected For more than 100 years, Siemens fuse systems have offered reliable protection for electrical systems and minimized potential risks to people and equipment.

M

elting fuses are characterized by high current limitations with short-circuit interruption, high switching capacity, small dimensions, excellent reliability and cost-effectiveness, and good compatibility with other protective devices. From the very beginning, Siemens took a leading role in the development of melting fuse systems.

Diazed and LV HRC fuses In 1908, the Siemens-Schuckertwerke already attracted attention in professional circles with the development of Diazed fuses. The basic design of a diametrically graded two-part fuse system with Edison thread (abbreviated to Diazed) not only achieved superior

family were an innovation at the time because a fuse element and a switch were combined in one device. The Diazed and Neozed (both trademarks of Siemens) low-voltage screw-in fuse systems have now been standardized internationally as the D system and are still known in the technical vernacular under the Siemens brand names worldwide. For the protection of power semiconductors, Siemens developed the superquick Sitor and Silized semiconductor fuses. In the Diazed, Neozed, LV HRC,

fuses have the required approvals. This is particularly important for machine and plant manufacturers that export their products.

Fuse systems in emerging markets

The areas of application of fuse systems range from cable and line protection, backup protection for switchgear, and semiconductor protection to protection of railway and photovoltaic systems, as well as of wind turbines. For the increasing number of demanding DC applications, such as in photovoltaic systems and wind turbines or for energy storage, Siemens is ready with fuse technology products. For special stand-alone solutions in the future market of the smart grid, such as energy generation and consumption on-site, Siemens offers customized and tailored fuse systems. In photovoltaic systems, for example, LV HRC fuses with high variable-load capacity and special gPV characteristic curves are used for 1,000-V or 1,500-V systems. Typical fuse components in wind turbines include LV HRC fuse switch disconnectors, Photovoltaic Sitor semiconductor fuses, and Minized systems are protected by switch disconnectors. LV HRC fuses The history of fuse technology develwith special opment at Siemens shows that the characteristic company’s many years of experience curves represent a significant advantage in developing contemporary solutions to address new requirements – for power and cylindrical fuse designs, they cover distribution or for the smart grid, for exmany areas of application – protection ample.

From February to December, bitumen production runs continuously at the Total Bitumen Deutschland site in Brunsbüttel, Germany. To ensure a continuous power supply, the company relies on high-performance systems that also enable transparent visualization of the electrical energy flows.

M

otorists know the energy company Total as the operator of Germany’s fourth-largest service station network, but its offerings of petroleum products go far beyond fuels and lubricants. The subsidiary Total Bitumen Deutschland GmbH, with more than 80 years of production experience, is among the leading manufacturers of high-quality bitumen for a wide variety of applications in road construction and industry. Since 1914, bitumen has been refined from petroleum at the Brunsbüttel site near Hamburg, conveniently located on the Kiel Canal. Because the distillation process can be interrupted only with great effort, production runs for 11 months of the year, and the continuous supply of raw materials, process gases, and energy must be ensured.

Wolfgang Geyer

• High flexibility thanks to innovative modular technology • High reliability and availability

The core of the new power distribution system at the Total Brunsbüttel site is a Sivacon S8 low-voltage power distribution boards

“In addition to the availability of power distribution systems, we also wanted to improve the transparency of the energy flows and ease of use,” says Ingwert Kock, who is responsible for electrical engineering at the Total Brunsbüttel location, summarizing the requirements of the new infrastructure. “That’s why we decided against the provider of the existing system, which is more than 30 years old, and in favor of Siemens.” The core of the solution is provided by several Sivacon S8 low-voltage power distribution boards for power distribution. These not only work very reliably but also offer the highest safety standards – for avoiding dangerous electric arcs, for example. Barriers help prevent faults from spreading in the system. Although the consumption points are only about 3 or 4 meters from the power distribution board, distribution is carried out with Sivacon 8PS busbar trunking systems. “Busbars can be run hotter than conventional copper cables,” describes Kock the advantage. “We can get by with much less material – a good and lean solution.” The busbar trunking systems also considerably reduce the fire load.

Visualization with Simocode A Simocode protective device switches on load contactors and other components. The compact control module also allows the operational data to be completely recorded and documented. All information on currents, voltage, and power can be queried in a simple and straightforward manner via Profibus DP. “Any student can do it,” says Kock. For the project engineer, easy operation is important: “We can program and maintain the Profibus system ourselves, without needing service technicians to come each time.”

The recorded data can be clearly displayed with Simocode. This is accomplished using WinCC flexible on a 15“ touchpanel. The maintenance and operating personnel thus always have detailed information. At the same time, the values form the basis for consistent energy management. This transparency of the energy flows has several advantages: the system components can be optimized, potential savings can be identified, and malfunctions can be detected at an early point in time. For example, if a drive is running with greater resistance than normal, this translates into higher power consumption. In addition, the consumption data show whether a motor is really running at full capacity during full-load operation or whether a smaller motor could be substituted, for example.

Easy operation During the replacement of the electrical power distribution systems at the Total Brunsbüttel site, the focus was on availability, reliability, and transparency of energy flows, as well as ease of operation. Siemens implemented these requirements with highperformance, low-voltage components. The solution also impressed Kock in day-to-day use. His verdict after two years: “The system runs smoothly – we are very happy with it!”

Integrated power distribution in the Leipzig Zoo’s Gondwanaland

Powered tropics Covering an area larger than the size of two football fields, Gondwanaland at the Leipzig Zoo opened in 2011 as Europe’s largest indoor tropical environment. The high availability of electrical power distribution makes a significant contribution to the safety and welfare of exotic animals and plants.

Highly available components The innovative TIP concept combines medium- and low-voltage components into an integrated and technically consistent solution. All components of the system were matched precisely to each other and optimally dimensioned using the software tool Simaris design. The result is a very efficient and reliable power distribution system from the infeed of the distribution grid operator to the consumption points. The dimensioning with Simaris design allowed the network to be selectively designed to quickly identify faults and accurately lo16

cate them. The corresponding faulty section is then switched off, while the rest of the power grid continues stable operation. To ensure the required high availability, almost all of the system components are redundant. The conversion from me-

Low-voltage power distribution at EnBW’s Heilbronn combined heat and power plant

Mission: Secure supply To be permanently available, a power plant itself must be reliably supplied with electrical power. At EnBW’s Heilbronn combined heat and power plant in southwest Germany, safe and highly available low-voltage power distribution is ensured by more than 160 3WL air circuit breakers.

T

he Heilbronn combined heat and power plant, with an electrical production capacity of 1,084 MW and a thermal production capacity of 300 MW for district heating, is one of the largest coal-fired power plants operated by EnBW Kraftwerke AG. Unit 7 of the power plant is the largest coalfired unit of the entire company. When completed in 1985, it set new standards in environmental protection. In addition to the district heating supply, it is also used for environmentally

friendly and resource- efficient incineration of sewage sludge. The Heilbronn plant is available 365 days a year for the production of electrical power and district heating. “The availability of all electrical systems is thus critical for us,” says Harald Widmann, who is responsible for electrical engineering at the site. All functions central to power plant operation require electrical power. The switchboard for internal requirements, including the control and monitoring

systems, operates entirely with low voltage. Siemens switchboards have long been used for the power distribution. Some 160 3WL air circuit breakers are deployed in four areas. The majority are located in the switchboard building, which contains approximately 50 switches. The other three areas are in the cooling and feed water treatment, the fuel supply, and the flue gas desulfurization. There are also 12 redundant switches for the DC distribution.

“ The 3WL circuit breakers are technically sophisticated and likely the best currently on the market.”

Power distribution | E-Installation 1/2013

Extensive modernization Over the decades, the circuit breakers reached their technical limits, and spare parts for the electronics were not widely available. EnBW thus decided to make a major upgrade in 2008. The most advantageous approach, technically and financially, was a retrofit solu tion implemented by the Cegelec Group. Only the switches were replaced; the control cabinets were retained and remodeled. Although remodeling during plant operation necessitated some technically complex adjustments in the area of the copper rails, the concept offered many benefits: the wiring and good mechanical components could be retained, allowing the conversion to be implemented much more quickly and cost-effectively. Personal safety has been improved with seamless touch protection in addition to complete partitioning. Most important, the solution now offers all the benefits of the latest generation of circuit breakers. The 3WL air circuit breakers are particularly versatile and feature consistent communication capabilities. They meet the increased requirements perfectly, especially in re-

gard to the monitoring and control of network processes with the use of electronic control systems.

Protection against overcurrent and short circuits With only three sizes, the 3WL air circuit breakers cover a power range from 630 A to 6,300 A. Designed with three or four poles, they are suitable for use with up to 1,150 V. All models feature the same design, the same mode of operation, and the same comprehensive set of accessories. The switches offer protection against overcurrent and short circuits with very high currents. If such currents are detected, the 3WL air circuit breaker electromechanically deactivates the relevant network segment. The tripping capacity upon short circuit is dependent on parameters such as the distance to the transformer. Thanks to the Simaris design configuration software, each of the 160 switches can be correctly set in terms of its protective function, even in plants of this size. The switches are Profibus compatible and networked using an ETU76B electronic trip unit. This allows all the cur-

rent values, operating states, and other indications to be visualized and processed at any time in the control center of the power plant. The Profibus connection also enables remote control of the switch using an integrated motor. Manual operation is also possible. As the new switches are designed with withdrawable-unit design, they could be preassembled by the Cegelec technicians. At the local site, the switches could simply be slid into the guide frame of the cabinet, which minimizes the cost of on-site installation and the shutdown period. And a defective switch can be quickly and easily replaced with a new one. Widmann and his team emphasize this aspect in particular: “In this way, we can ensure the availability of our systems at all times, even when there is no specialized expert on-site.”

Architecture with special requirements

The new Stuttgart City Library building sets standards with its sophisticated architecture

As multimedia learning centers and cultural venues, libraries are central to a vibrant community. This role leads to special requirements for premium architecture, as well as for reliable and efficient electrical engineering – requirements that were fully met in the new Stuttgart City Library building.

S

tuttgart’s central library in the Wilhelmspalais was once considered one of the most modern libraries in Germany. In the early 1990s, however, it became clear that it would soon reach its limits in terms of space. In 1997, the opportunity arose to plan a new building on the future Mailänder Platz and thus create a vibrant new educational and cultural institution for the city. 24

In October 2011, the new Stuttgart City Library was inaugurated after nearly three years of construction. The design, by Korean architect Eun Young Yi, created a striking monolithic structure of concrete and frosted glass block, with nine aboveground and two underground levels. At a height of 40 m, the edifice towers over the adjacent buildings, sets new architectural standards, and also un-

derscores the importance of the city library as an intellectual and cultural center. The building envelope is a double facade featuring a glass-block level in a light gray, exposed-concrete frame and an inner mullion and transom facade with sun protection as a thermal envelope. The space between the two facades can be used as a walkway for strolling and is illuminated in blue at night.

To ensure full fire protection in accordance with DIN VDE 0833-2 Annex G, despite the special circumstances, Siemens added 800 fully automatic smoke detectors to the sprinkler system. If they are triggered, the ventilation system is used to carry away the smoke. The various security systems, which include eight video cameras, five access control readers, and the 680 loudspeakers of the public address system, are connected with a Siemens control center for around-the-clock monitoring. In the event of an alarm, this system allows visitors and staff to be quickly informed and responsible bodies, such as the fire and rescue service, to be coordinated in a targeted manner. The Total Building Solutions are rounded out by approximately 3,900 high-quality energy-efficient luminaires and 380 facade lights, ensuring optimal lighting conditions. The sophisticated technical solutions thus fit the unique architecture of this new civic center, making a visit to the Stuttgart City Library a special experience.

time ensuring the greatest possible energy effi ciency. When a guest checks in at the front desk, the lighting system is activated in his or her room. When the guest opens the door and inserts a key card into the hotel card switch, the welcome scenario is activated, in which several lamps and energy-saving LED light strips are switched on automatically. Near the bed are two switches equipped with LED lights: “Do not disturb” (DND) and “Make up room” (MUR). Thanks to Gamma instabus, which is based on the global Knx standard, the staff can recognize the preference of the guest outside the room: with “Do not disturb,” a red indicator automatically lights up; with “Make up room,” there is a green light. Thanks to corresponding software, this information can be visualized centrally for all the rooms, allowing management to optimize service. If the guest does not wish to be disturbed and someone presses the bell, it remains silent in his or her room. Only the LED light on the corresponding button is activated for 10 seconds. The room automation with Logo! and Gamma instabus also makes it possible to switch off all the lights at once simply by pressing a switch at the head of the bed. When the guest leaves the room and pulls the key card out of the hotel card switch, after 30 seconds all the lights will be turned off automatically to save energy and reduce costs. Should there be a power failure, all the room lights remain in the state in which they were immediately before the loss of power.

In the other areas of the hotel, convenient and energy-saving scenarios were also implemented, thanks to Gamma instabus. For example, in the conference rooms, the lighting, curtains, and projection equipment are controlled using a Gamma touchpanel. At the touch of a button, the conference host can activate fi ve different scenarios: for greeting, projection, break, end of conference, and farewell. Guests can also switch on the light in the spa and fitness area using their key cards. The light can be switched off only at a central touchpanel, as it is possible that other guests may be in this area. The hotel’s general lighting system for hallways, the entrance hall, and staff rooms is centrally controlled from the reception desk or automatically by a program. With this comprehensive Total Building Solution, the DoubleTree by Hilton Istanbul-Moda meets all the requirements for a representative and prominent member of the Hilton family.

ally and in his private life, for 20 years. This knowhow also benefits customers of Drees & Sommer. The company assists private and public developers and investors in all aspects of real estate. If electromobility is required within the scope of building use, Drees & Sommer handles the planning of the required infrastructure. In this way the company is setting new standards in the areas of process consulting and development management, as well as in project management, real estate consulting, and engineering. Drees & Sommer always tries to create measurable added value for its clients, with a meaningful connection between economy and ecology, such as lower energy costs thanks to innovative ideas and technologies.

sponding switchgear. The charge controller, in accordance with the IEC EN 61851 standard, detects the requirements of the vehicle to be charged and automatically releases the correct charging power. In this way, accidental overcharging is prevented.

Innovative technology readily available In addition to its functionality and quality, an important argument in favor of the Siemens WB100A charging unit was its immediate availability. The responsible sales representative, Mile Miletic of the Siemens Low and Medium Voltage Division, confirmed: “We can deliver within a few business days. After all, we have extensive experience in the area

“Another argument that was convincing for us was the immediate availability of the charging unit. Unlike almost all other providers, Siemens Wolfgang Geyer

includes these units in its standard catalog.” Ralf Wagner, Project Partner, Drees & Sommer

Sophisticated charging management Wagner believes that if a building has more than two electric cars, sophisticated load management is necessary to keep the building power consumption within limits. At the location in Stuttgart, the charging station in the underground garage was easy to retrofit because the connection was already provided in the construction of the building. The installed WB100A charging unit (wall box) with 32 A and plug type 2 allows vehicles to be charged in charging mode 3 in accordance with IEC EN 61851, with a charging cable and plug in accordance with IEC EN 62196. The WB100A ensures the required safety of people, vehicles, and the charging unit with miniature circuit breakers and residual current circuit breakers from the Sentron line. The high safety standard does not in any way compromise the problem-free use of the wall box. It can be installed quickly and space efficiently, and it is very easy to operate. Instead of a gasoline pump, a plug is plugged into the car, and the charging process starts automatically. The display indicates when the process is complete. A standard-compliant CM-100 charging controller from the Siplus series is integrated into the charging unit. It communicates with the electric vehicle and controls and monitors the corre-

of electromobility and are committed to driving innovation.” The Siemens charging station installed at Drees & Sommer was selected to ensure sufficient spare capacity. Instead of the currently required 6.6 kW, load requirements of up to 22 kW can be accommodated if required for any new vehicles with higher requirements. The electrical power for the entire company, and thus for the electric car, comes from renewable sources. This means the vehicle is emission-free and has substantially lower energy costs per kilometer than cars with a combustion engine. The latest steps in implementing the “blue way” concept for integrated and sustainable thinking and action are moving in the right direction for the company’s complete conversion to renewable energy and the use of electromobility as a pioneering technology.
