通过采用一种晶闸管投切电容器和静止同步补偿器集成的混合无功补偿的系统设备控制电压,该补偿系统可在电网正常时协调电容器组与静止无功补偿器,实现并网点无功功率的实时、连续控制,有效提高并网点电压质量;在故障及故障恢复时刻,提高并网点电压支撑能力。最后采用电力系统分析综合软件(PSASP)建立了CEPRI7节点系统模型,对系统控制策略进行了仿真分析,结果表明该混合无功补偿系统具有可行性与有效性。

This study has actulized voltage control through the adoption of a thyristor switched capacitor and static synchronous compensator integrated mix system of reactive power compensation equipment.The compensation system can coordinate capacitor banks and static reactive power compensator,in normal power grid and effectively improve the quality of voltage and branch in a real-time,continuous control,way during node reactive power.At the time of fault and fault recovery,the system can also improve the voltage support capability of parallel node.Finally,the CEPRI7 node system model has been established by power system analysis software package(PSASP),and the system control strategy has been simulated and analyzed.The results show the hybrid reactive power compensation system is of great feasibility and effectiveness.
