A Novel Cost-Effective Circuit Topology for Reactive Power Compensation in Electrical Grids

Abstract:
With the circuit topology presented in this paper, it is possible to construct reactive power compensation devices, which are significantly cheaper than comparable SVC (Static Var Compensators), though they exhibit nearly the same functional properties. Operating principles and economical aspects have been examined and compared with two other devices for reactive power compensation in electrical power grids with similar properties, namely SVC and MCSR (Magnetically Controlled Shunt Reactor). The proposed circuit topology is especially advantageous in the high-voltage grids (110 kV and above) or for applications as a pure controllable shunt reactor.
