Synthetic Evaluation and Field Experiences of Large Capacity Synchronous Condenser Application to a Bulk Electric Power System to improve System Operation Characteristics

Abstract

Reactive power supply sources with excellent voltage and dynamic stability characteristics are required to maintain system stability in a large-scale heavily loaded power system. The authors carefully examined the effectiveness of synchronous condenser application to such a power system in improving the stability margin. In an analysis example of a large, actual power system which has a comparatively higher nose tip voltage, a large capacity synchronous condenser can lower the nose tip voltage by about 4kV on the same demand conditions compared with shunt capacitor case. A large capacity synchronous condenser applied to a large-scale heavily loaded power system achieved the expected results with good operating characteristics.
