| 摘 要： | 建立了变电站10km电力传输系统、并联电容器组及工厂负荷模型,基于PSCAD仿真结果分析了在异步和同步两种策略下投切电容器组时产生的涌流和过电压的变化.结果表明,与异步投切相比,同步投切电容器组时产生的涌流和过电压较小,因此改善了电网暂态稳定性、提高了输电质量、保护了电网器件.研究结果有助于工厂根据自身的投入成本及电压...

| Abstract: | The 10km power transmission system of transformer substation,the parallel capacitor banks and the factory load models are established in this paper.Also the over-voltage and inrush current waves are obtained from switching condenser bank with synchronous and asynchronous strategies in PSCAD and analyzed.The analytical result of above indicated that the fluctuation of switching with synchronization is smoother than asynchronous strategy.So the transient stability is improved and the transmission quality is enhanced,also the electrical component is protected with it.The finding is helpful to the factories in selecting suited reactive power compensation based on the input costs and voltage level required of their own. |
