南方电网交直流并联系统电压稳定分析及STATCOM应用仿真

Voltage stability analysis of South China's hybrid AC-DC power system and research of potential application of STATCOM (ASVG)

采用大型电力系统分析软件NETOMAC对2005年南方电网进行仿真计算,并针对广东电网多直流落点、大功率区外输入的特点进行受端系统的电压稳定分析,讨论三广直流闭锁引起的典型电压失稳现象;就南方电网应用STATCOM解决电压稳定问题进行仿真研究,并讨论直流调制对系统电压稳定性的影响。

This paper briefs the simulation of transient stability of South China's power system with NETOMAC, and the analysis and conclusion of the voltage stability of Guangdong power system, which has several HVDC lines and needs faraway large-scale power supply. The potential applications of STATCOM and DC Modulation to solve this realistic problem of current heavy burdened power systems are dis- cussed.
