| 摘 要： | 本文在分析串联电容和并联电容补偿调压原理和特性的基础上,定量分析了串联电容和并联电容共同调压时的交互影响,指出串并补之间存在交互影响的根本原因是并补使流过串补的无功电流减少,串补使系统的等效阻抗降低.仿真研究表明:负荷电流大小和串联电容补偿度是影响串并补交互影响的关键因素:串并补共同作用可以降低系统电压的波动范围.

| Abstract: | To analyze the interaction of the series capacitor compensation(SCC) and parallel capacitor compensation(PCC),the principle of SCC and PCC and their characters are introduced firstly in the paper.Then quantitative analysis of the interaction between SCC and PCC is done,and it is pointed out that the PCC makes the reactive current through SCC reduced and SCC makes the system equivalent impedance reduced,which are the basic reasons causing the interaction of SSC and PCC.Simulation results show that the load c... |
