中文摘要:
      提出一种考虑统一潮流控制器(unified power flow controller,UPFC)系统级和换流器级控制策略的线路功率调节能力计算方法,实现了电网正常运行和N-1情况下UPFC对线路潮流有效控制范围的计算。首先介绍了UPFC工程的控制策略,考虑并联侧定电压控制和定无功控制特性的基础上实现潮流分析,并以南京西环网UPFC为例,在PSS/E中基于江苏电网的实时运行数据对UPFC的实际潮流控制范围进行计算,为电网调度运行提供参考。
英文摘要:
      This paper proposed an algorithm of calculating the capacity of UPFC based on both system and converter strategy. Then the compari-son of effect in normal and N-1 situation is researched. At the beginning, control strategy of UPFC in Nanjing western power grid is introduced, while a power flow method based on UPFC parameters, voltage and reactive power control modes. Hereafter, control range of UPFC is computed by PSS/E and Python language in the real-time data of Jiangsu power grid. The result could be able to improve the safety and reliable of Jiangsu power grid.
