SICAM eRTU 6MD22 Substation

Description

Ever greater demands are made on the reliable operation of supply systems for electricity, water, gas and district heating, as well as on industrial and private sewage disposal systems. The demand for economic efficiency and for short downtimes, along with a wider understanding of environmental aspects, sets high standards of performance, reliability and availability of these systems. The central monitoring and control of these geographically widespread systems, as well as a quick reaction to possible faults, are important prerequisites for reducing the cost of system management. An optimal solution is available with the SICAM eRTU system which combines the specific functions of a telecontrol unit with the versatility of a programmable process automation system covering technical processes at different locations within a substation or system. The basis of the new, powerful SICAM eRTU system solution is the SIMATIC S7-400 programmable logic controller with a multitude of communication possibilities and a universal functionality. This forward-looking platform was supplemented by components for increased demands on telecontrol technology and matched to the main functional aspects of the substation control and protection system.

SICAM eRTU opens up extended functions and performance ranges The SICAM eRTU (enhanced RTU) telecontrol system is based on the familiar SICAM RTU in terms of its basic functions and its technical design. In comparison with SICAM RTU, it is notable for additional distinctive functions and enhanced system performance. Besides a series of manufacturer-specific protocols, standardized data transfer protocols (such as IEC 60870-5-101 or IEC 60870-5-104) ensure reliable and real-time transfer of indications and of measured and metered values to higherlevel control centers. • Telecontrol communication

Bay Control Units

Via MCP assemblies, up to 96 bay control units (IEDs) can be connected directly to SICAM eRTU with the IEC 60870-5-103 or DNP 3.0 protocol. The interfaces can take the form of RS232, RS485 or a fiber-optic link. Communication with sub-units supports the command and indication direction. Status indications and commands from/to substations, protection units and IEDs can be combined to suit requirements via CFC (Continuous Function Charts) and processed further to suit the user’s specific needs. The bay control units can be selected out of a catalog in SICAM plusTOOLS and configured by Drag & Drop. The catalog contains SIPROTEC V3 and SIPROTEC V4 protection and bay control units, tap voltage controllers (Reinhausen, Eberle) and protection units from third-party manufacturers. After selection from the bay control unit catalog, the full scope of information of the bay control units is available in SICAM plusTOOLS. This scope can then be reduced to suit the requirements of any specific project. As an alternative to selection from the catalog, the interface descriptions generated with DIGSI 4 can be imported, and thus the interface scope defined in DIGSI can be directly adopted. In this way, the optimal scope of information for the specific system is available to operating personnel in the controlling and monitoring direction. The name SIPROTEC 4 stands for an innovative range of numerical protection and bay control units with – open communication interfaces, – an ergonomically designed user interface and – flexible functionality.

Simple installation The modules are inserted and screwed into the subrack. It is connected to the S7-400 bus system automatically as soon as it is inserted, by means of 5-tier bus connectors on the rear of the housing. User-friendly wiring The process wiring is connected via an S7-400 front-panel connector. Several alternative modes of connection are available: • Front-panel connector with

screw-type terminals for flexible wires with a cross-section of up to 1.5 mm2.

DI32 Digital Input

The DI32 digital input functional module is used for inputting digital process signals. It enables the interference-free and fast acquisition of digital process signals. The inputs are isolated against the electronic parts. The advantages of the DI32 • No need for external interme-

diate relays thanks to the integrated isolation up to 2.5 kV.

• Flexibility for processing differ-

ent input voltages thanks to wide-range inputs.

• Fast, reliable signal acquisition

with a real-time resolution of 1 ms.

• One process interface, two pro-

cessing modes:

– Spontaneous event acquisition with real-time stamp in event buffer for 200 entries. – Cyclic state acquisition with process image of the inputs (PAE). Inputs The DI32 digital input module has 32 inputs for binary process signals: • The inputs are arranged in four

groups of eight inputs each.

• The processing function can be

selected and parameterized separately for each group.

• The inputs cover a

wide-range voltage from 24 to 60 V DC or 110 to 125 V DC.

Filters

Operating modes of the DI32

Filters prevent the input signal from being detected erroneously. The DI32 has the following input filters:

The process changes detected are processed further by the DI32 simultaneously in two operating modes:

• Chatter blocking

for suppression of huge bursts of indications in case of defective signal generators or intermediate relays.

10

Siemens SICAM 2.4.1 · 2003

acquisition “Spontaneous event acquisition” means that the detected changes of state are entered chronologically in the event buffer. The DI32 outputs a process alarm (PRAL), which causes the data stored in this buffer to be retrieved by the CPU. Up to 200 entries with time stamp can be buffered.

• Cyclic acquisition of state

These memory addresses can be selected directly by the central processing unit (CPU), in order to read the data. The PAE is always updated, regardless of the currently active processing function.

SICAM eRTU 6MD22 Substation

CO32 Command Output

DI32 Digital input (cont’d) Processing functions The detected changes of state can be processed further in the following ways: • Single-point indication

Each incoming or outgoing input signal causes data to be entered in the event buffer and the process image to be updated. • Transient indication

Each change in the input signal causes the process image to be updated. However, only an incoming input signal causes data to be entered in the event buffer. • Double-point indication

Two defined states of an operational device (e.g. on/off) and two undefined states (e.g. intermediate state information) can be represented with two inputs. Each change in the double-point indication causes data to be entered in the event buffer. Each new state of the two inputs is entered in the process image. • Bit patterns

Several inputs of a DI32 are used to detect freely definable states of an operating device. This information can be transferred to the event buffer by an internal event signal (change in the bit pattern) or an external event signal (impulse via a fixed external input). • Transformer tap indication

Several inputs are used to detect the states of a transformer tap generator. This information is transferred according to the moving contact. The transformer taps can be entered in variable codes. • Metered-value acquisition

Signal changes are interpreted as metering pulses and totalized. The metered value is transferred to the event buffer by means of a transfer job.

CO32 command output

Outputs

The CO32 command output functional module is used for outputting isolated, protected switching commands. It enables the interference-free output of digital process signals. The outputs are isolated against the electronic parts.

The command output module has 32 isolated outputs, arranged in two groups of sixteen and each with a separate output circuit.

The advantages of the CO32

• Time-controlled command

• No need of external control

intermediate relays thanks to the powerful output relays with integrated isolation up to 2.5 kV.

• Operating modes with 1,

The process data can be output via the CO32 in two different ways: output via the job buffer.

• The commands can be out-

put either continuously or as pulses (max. time interval: 60 s), depending on the process requirements.

• AII commands are effected

and terminated safely, even if the CPU fails.

CO32 Command Output

CR Command release The CR command release module is an expansion module for the CO32 command output modules. It is used for an isolated, interference-free and reliable output of digital process signals. The outputs are isolated against the electronic parts. The advantages of the CR • The functions integrated on

the CR enable the command output circuit to be distributed between two separate modules, so that the reliability of the command outputs is improved significantly in line with the stringent VDEW requirements:

– Isolation of the command output circuit tested. – Impedance of the command output circuit tested (switching current check).

Fig. 11 Circuit diagram for “1 pole plus 1 common pole command output”

– Output voltage monitored. (Cont’d) Operating modes Various operating modes are available, depending on the safety requirements: • 1 pole plus 1 common pole

for the command output

The actuators are controlled with 1 pole plus 1 common pole, i.e. one terminal of the actuator is applied to the command output voltage via the output relay, while the other is applied to it via the common return line and the release contact on the CO32. Due to the use of the release contact, the actuators are de-energized when they are not controlled. • 1-pole command output

32 outputs are available only one of which can be connected at a time (1-out-of-n test). The output relay is controlled by means of the job buffer as a function of time.

12

Siemens SICAM 2.4.1 · 2003

• 2-pole command output

The two-pole control of the actuators is made possible by 16 two-pole-outputs. Both the actuator terminals are applied to the command output voltage via the output relay and the switch connected in series with it. In this mode too, the actuators are de-energized when they are not controlled. The release contact is not used. • Unverified digital output

Two-pole control of the actuators means that 16 outputs are possible. The outputs are controlled cyclically by means of the PAA. Several different outputs can thus be controlled simultaneously and independently of one another. The output time interval is set in the user program by means of the PAA.

• Command output

In the command output operating mode the software performs a command address check and an 1-out-of-n test by back-reading the outputs.

– Command output time interval monitored. – There are additional system-specific in- and outputs on the CR: – 8 isolated relay outputs (e.g. for system and operational indications). – 8 binary inputs for fast, reliable signal acquisition with a real-time resolution of 1 ms. • It is also possible to insert a

number of CR modules assigned to specified CO modules.

Thus, various command output circuits are possible.

SICAM eRTU 6MD22 Substation

CR Command Release

Command release (Con’d) The CR switches the output voltage to the command output circuit via powerful, two-pole contacts according to the results of a series of test criteria. This switching concept has a number of advantages: • The complete command out-

put circuit, including the CO32 command output module, is de-energized in the idle state up to the intermediate control relay.

• The complete command out-

put circuit can be tested (while de-energized) for isolation, short-circuits, open circuits and parallel connections (switching current) before a command is released.

• The command output circuit is

distributed between two separate modules. The reliability of the command outputs is thus improved significantly.

Check for potential This test detects conductive connections between the command output circuit and the output voltage or other disturbing voltages. It enables the following wiring faults and defects to be identified: • Conductive connection be-

tween the command output circuit and the output voltage.

• Isolated DC voltage ( 2 V) in

the command output circuit.

If the command output circuit is looped via a CO32, the abovementioned faults and defects between the CO32 and the CR, on the CO32 or between the CO32 and the connected load relay can be detected. If the output circuit is connected in a way which is not permissible, no command output voltage is switched through and the command release is aborted.

Fig. 12 Principle of the CR command release circuit

Switching current check

Output voltage monitoring

Digital inputs

The switching current check function permits the resistance of the command output circuit to be determined with just one measurement and compared with the parameterized value.

The CR functional module monitors the command release voltage before a command is released. In the event of an impermissible deviation (< 17 V), no voltage is switched through and the command release is aborted.

Eight binary inputs are provided on the CR for general process inputs.

It enables the following wiring faults and defects to be identified: • Short-circuit in the command

output circuit.

• Open circuit in the command

output circuit.

• Connection of another type

of load resistor.

• If the impedance of the out-

put circuit exceeds the permissible value (tolerance + 30 % / - 20 %), no command output voltage is switched through and the command release is aborted.

Relay outputs The eight relay outputs provided on the CR are general digital outputs. They are not interlocked by additional hardware functions. The eight binary outputs take the form of four changeover contacts and four normallyopen contacts.

They are arranged in a group with common potential and can be used for either spontaneous processing (via the PAA) or cyclic processing (via an event buffer for 50 events). The following applications are possible, for example: – Monitoring door contacts – General interrogations – LED-test – Indication of the release of a miniature circuit-breaker (fuse faults).

The following applications are possible, for example: – Cubicle lamp – Substation fault indication (e.g. for controlling an alarm annuncation unit) Each output can be programmed to output commands either continuously (via the PAA) or as pulses (via the job buffer PAA).

AI32/AI16 Analog Inputs

The AI32 and AI16 analog input functional modules are used for inputting analog process signals. They enable the fast and interference-free acquisition of 32 or 16 analog measured values with a resolution of 12 bits plus sign. The inputs are isolated against the electronic parts. The advantages of the AI32/AI16 • No need for expensive isolating

transformers thanks to the integrated isolation up to 2.5 kV.

• Flexibility thanks to wide cur-

rent and voltage ranges.

• Fast, reliable signal acquisition

with a real-time resolution of 1 ms.

• One process interface, two

processing modes:

– Spontaneous event acquisition with real-time stamp; storage if a threshold value is exceeded in event buffer for up to 100 entries. – Cyclic acquisition of the current analog measured values by means of a process image of the inputs (PAE). • Reduction in the amount of

data sent to the CPU thanks to threshold-dependent preprocessing of the process signals.

Fig. 13 Processing principles of the AI32/AI16

Inputs

A/D converter

Measured-value acquisition

The AI32 has 32 analog inputs with common potential that is isolated from the electronic section. The AI16 has 16 analog inputs which are isolated from one another and from the electronic section. Either current or voltage inputs can be supplied.

The A/D converter is designed in accordance with the sigma-delta principle, a modern method that ensures interference immunity.

The analog process signals which are present at the inputs (measured values) are processed by the analog input modules simultaneously in two different ways.

• Voltage inputs with high im-

pedance, so that only a small load is placed on the voltage source.

• Current inputs equipped with

high-precision shunts. They are less sensitive to interference owing to the low impedance of the measuring-circuit termination.

All inputs are protected against overvoltages and transients by means of suppressor diodes and RC networks.

Siemens SICAM 2.4.1 · 2003

The filter times, the resolution and the gain can be parameterized. The conversion time for one measured value is approximately 30 ms if the interference suppression is set to e.g. 50 Hz. Self-calibration The analog input modules are self-calibrating. The modules are equipped with precise, low-drift reference voltage sources for this purpose. They carry out a zero and full-scale calibration automatically each time it is switched on as well as at regular intervals, in order to reduce the temperature drift to a minimum.

• Cyclically

The normalized measured values are entered cyclically in the process image of the inputs (PAE). The PAE is always updated in cyclic mode, regardless of any other functions. • Spontaneously

The measured values are entered in the event buffer if a parameterizable threshold is exceeded (threshold processing).
