Asta
Veera
(29-30 July)
(4th of August)
Storms in Finland 2010 • 4 storms; Asta, Veera, Lahja and Sylvi • 35,000 km of electric power network were damaged.
Lahja
Sylvi
(7-8th August)
(8-9th August)
• 9,000 distribution substations were left without electricity. • Repair work nearly 200,000 hours (over 120 man-years). • Affecting about a third of Finland's electricity network companies • Led to long power cuts. The longest individual power cuts lasted around six weeks.
2
Communication network failures during the 2010 storms: • Asta: 1050pcs GSM and UMTS Base stations, 38pcs TETRA Base stations out of function • Veera: 525pcs of GSM and UMTS Base stations, 25pcs of TETRA Base stations out of function • Lahja and Sylvi:1072pcs of GSM and UMTS Base stations out of function.
3
Substation failure, Nederland, 27.3.2015 • 240000 homes effected • 1 million people effected • Substation backup failed too
Power outage in Europe, November 6, 2006 • 15 million people effected • Portugal, Spain, Belgium, Italy, Nederlands, Geramany, France

Challenges • How to remote control re-closer stations? • How to control re-routing? • How to monitor the node status in the grid? Public communication networks are down • Loss of power SOLUTION: Radio modems • Run on battery for days
How to swap? • Automated path selection • Route monitoring, standard protocols X
RTU Radio modem can select path autonomousl y
SMART GRID – COMMUNICATION NETWORK Smart Grids and solutions Need of more functions, more intelligence • Increasing amount of information requires high reliability and availability in wireless communication networks • The communication network has to be reliable and safe • The communication networks has to survive extreme weather and environmental conditions
Requiring higher reliability, availability and quality More remote control and measurements
Cost efficiency Remote operations, grid automation, shorter downtimes
Reliability Redundancy • High requirement for availability to primary substations • High requirement for availability to remote control Smart Grid devices

TECHNOLOGY SUMMARY – PRIVATE NETWORK - RADIO MODEMS Transmits data wirelessly to another radio modem in a point-to-point, point-to-multipoint or multipoint-to-multipoint network • Operating in 25 kHz frequency channel it is a spectrum saving method of data transmission • Support for serial (IEC-101) and IP based (IEC-104) based protocols • Fast polling
Independent of mobile, satellite, or any other third party network operators • • • •
You are in total control of your network No data transfer costs (Cost efficiency) High Safety and security Easy to manage , maintain and expand
• • • •
High reliability in all weather conditions Easy to roll out Excellent availability and reliability No forced migration to next “Gs”
Supporting a wide range of VHF and UHF frequencies Radios for both licensed and license free frequencies are available
specialized in mission critical wireless data communication systems • • • • •
Widest selection of products in its field Worldwide distribution network Engineering and project management Installation, commissioning and maintenance services Complete tailored data communication solutions and systems for telemetry communication need
