Controlled Series Compensation of High Voltage Lines to Increase Transmission Capacity

Nowadays the Russian electric power system as the biggest power net in the world has problems with synchronization of the remote areas with the basic electrical system. Moreover, the industrial development and growth in the number of consumers require an increase of existing lines transmission capacity. The construction of new power transmission lines causes high economic costs. The huge amount of researches figured out that the installation of controlled series compensation devices at long-distance power transmission lines with voltage of 500 kV and higher is able to significantly increase the transmission capacity of the power transmission line and increase the level of stability. The aim of this paper is to investigate the effects of the series compensation devices installed on 220 kV lines on stability and the current load of system elements. In this regard, it is advisable to analyze the aperiodic steady-state stability of an electric power system containing 220 kV power lines and issues of improving the transmission capacity of the power transmission lines.
