UPFC在安徽电网中的应用与研究

Application and Research of UPFC in Anhui Power Grid

基于UPFC的基本原理,综合安徽电网关键线路潮流计算结果和N-1故障过负荷情况,确定了安徽电网UPFC的最佳安装位置。搭建合肥地区等值电路仿真模型,通过UPFC合理转移安徽地区重载潮流,降低N-1故障下线路潮流过载倍数,来调节母线节点电压。通过对安徽电网建模仿真,UPFC能够有效解决安徽电网潮流分布不均、系统潮流过载和维持节点电压稳定的问题,提高电网的利用率和运行安全稳定性。

By analyzing the basic principles of UPFC,integrating the calculation results of power flow in key lines of Anhui power grid and the overloaded condition in case of N-1 fault,the best installation location of UPFC was got. The equivalent circuit simulation model in Hefei area was established. UPFC was used to transfer overloaded power flow in Anhui,the multiple of the overloaded power flow caused by fault was reduced so as to adjust the bus node voltage. The research to Anhui power grid modeling and simulation conclude that UPFC can effectively solve the problem of uneven power distribution in Anhui power grid,overloaded system power flow and maintaining stability of node voltage,also improve the utilization rate,safety and stability operation of Anhui power grid.
