摘要
根据河南电网2015年规划的网架数据,对河南电网进行仿真分析,研究SVC对其电压稳定性的影响。采用BPA作为分析软件,结合稳定曲线分析工具,对河南电网500kV线路严重故障后的暂态稳定性进行仿真,提出在电压支撑薄弱的豫西地区进行SVC的配置,对配置后的故障情况进行仿真,对比SVC配置前后的安全稳定性控制措施。结果表明:配置SVC以后,在河南电网发生相同严重故障情况下,安全稳定性控制措施总量大大减小,SVC有效地提升了河南电网的电压稳定性。
According to the planning data of Henan power grid in 2015,the dynamic voltage stability of Henan power grid is analyzed.By combining analytical software and the stable curve analysis tool of BPA,the transient stability of Henan power grid when a serious fault occurring on 500kV transmission lines is simulated.Then Static Var Compensator（SVC） is suggested to be installed in the west of Henan province which is weak in voltage supporting,and the security and stability control measures before and after using SVC are compared.The simulation results show that the amount of control measures is greatly reduced by applying SVC for the same faults occurring in Henan power grid,which effectively improve the voltage stability of the Henan power grid.
