摘　　要：随着上海500kV网架结构的发展,受短路容量的限制,南桥、杨高、徐行、顾路等分区必将分片运行;500kV母线或联变的故障、三峡直流大功率的突然闭锁以及外高桥二期2×900MW机组的突然停运,均有可能造成上海电网电压稳定性的破坏。介绍了上海电网电压稳定目前存在的问题,分析并提出了配置动态无功装置的可行性建议。With the development of the 500 kV network in Shanghai and because of the limitation of short-circuit capacity, the districts such as Nanqiao, Yanggao, Xuhang and Gulu are bound to operate separately. The fault in 500 kV busbars and coupling transformers, the sudden lockout of the Three Gorges direct power and the sudden shutdown of the 900 MW units of Waigaoqiao No.2 Power Generation Co., Ltd. would probably result in the voltage instability in Shanghai Power Grid. The currently existing problems in voltage stability of Shanghai Power Grid were introduced and the feasibility suggestion on configuring dynamic reactive equipments was put forward and analyzed.
