The system measures for short circuit current limitation in megalopolis at the example of Moscow-city power system

The consumption increase, generating capacities and electric grid development in Moscow region and especially on Moscow-City territory in short-term and long-term perspective will lead to the short circuit current increase to ultrahigh values which exceed the disconnection capability of the serial equipment. The present article covers the issues of short circuit current limitation in megalopolis power system taking Moscow Power System as an example. The issues of consumers' power supply reliability were considered. The foreign experience of short circuit current limitation in megalopolis was analyzed. The system approach for solving this problem was proposed. The future recommendations for energy companies were developed.
