电力系统电压/无功控制策略研究综述

A survey on voltage/reactive power control strategy for power systems

针对近年来国内外典型的电压/无功控制策略进行总结与评述,如九区图法、五区图法和模糊控制、专家系统、神经网络等智能优化控制方法,全面分析比较了其设计思想、调节判据及各自的优缺点;并结合电力系统通信、电压稳定性、自动电压控制技术的最新发展,就电压无功控制最新成果进行了综述;最后对未来电压无功控制在电网运行中有待于研究的问题提出了几点展望。

In the paper, the classical voltage/reactive power control （VQC） strategy are concluded and discussed, such as nine-area theory, five-zone theory and intelligent optimal control strategy including fuzzy control, expert system, neural networks and so on. Their fundamental ideals, regulating criteria, advantages and disadvantages are analyzed and compared. The prospect of VQC is also brought forward in terms of electric power communication, voltage stability and AVC. Finally, some opinions of the awaiting research of VQC in electric network operation are brought out.
