摘要
现代电力系统面临着越来越高的短期电压不稳定风险,快速电压崩溃和延迟电压恢复是两种典型的短期电压不稳定现象。介绍了短期电压不稳定的有关概念,讨论了短期电压稳定性分析的模型要求和抑制短期电压不稳定的动态无功补偿问题,并结合算例系统对相关问题进行了时域仿真分析。
There is higher and higher risk of short-term voltage instability in modem electric power grid such as that of fast voltage collapse and delayed voltage recovery. Introducing the related basic concepts of short-term voltage stability, this paper discusses the modelling issue for the instability and the dynamic VAR compensation for its mitigation. Simulation studies are carried out with a small test system for demonstrating the above issues.
