Elektrilevi will receive a cutting edge network management system
The biggest Estonian network company Elektrilevi has entered into contract with the international energy company Schneider Electric for the purchase of a world-class network management system. The management system that meets the needs of a modern smart network costs 2.3 million euros and it will be put into service by the summer of 2020.
“There are an average of 500-600 events taking place in Elektrilevi’s network each hour and the control centre must receive accurate and operative data about these - be it maintenance works, a tree fallen on a power line or the redirection of a power connection necessary for the construction of the network, for example,” said the head of Eelektrilevi’s control centre Jüri Klaassen. “In order for all these events to pass as unconcernedly and unnoticeably as possible for the customers, the management system of the network must be top-level,” he added.
According to him, the development of distributed power generation and an increased two-way traffic in the network set heightened requirements for network management. Also cyber security must take an equal pace with the increasingly smarter network.
The network management system of Schneider Electric is used in 80 countries all over the world and approximately 100 million people receive electricity by means of it. Of Estonia’s closest neighbours, the same system is used in Finland by the network company Caruna and in Sweden by Ellevio.
Compared to the current management system, which has been in use since 2010, the new system has improved distribution network monitoring and remote control. Also, the new management system has additional features, which support the smart network conception and real-time network control. The complete solution meets the security requirements applied for information systems with vital service provision.
The transition to the new SCADA type of management system will begin this summer and will be put into service from June 2020. The system will go through various tests during these two years, which need to ensure the security and functioning of it in the Estonian power grid conditions. Elektrilevi trains their network dispatchers with a special training simulator for the implementation of the new system.
Elektrilevi is the largest distribution network company in Estonia and manages approximately 60,000 kilometres of power lines and 24,000 substations.
