摘要
随着电力系统的发展,互联电力网络变得越来越大,暂态稳定性问题日趋严重,而电力系统安全运行的关键之一是可靠的暂态稳定分析。通过介绍电力系统暂态稳定分析常用的几种方法,回顾电力系统暂态稳定的发展历史和现状,对比分析了几种方法的特点及适用范围,并在此基础上对电力系统暂态稳定分析的发展前景进行了展望。最后指出,小波分析用于电力系统暂态稳定分析具有广阔的发展空间,特别是在处理暂态信号方面,更是一个很有应用价值的研究方向。
For the interconnection power grid expands rapidly with the development of power system,its transient stability becomes increasingly seriously.The reliable transient stability analysis is one of the keys in safe operation of power system.The developing history and status quo of power system transient stability technology is reviewed in the paper by introducing the common methods of power system transient stability analysis.The features and applicability of various methods are analyzed in detail.The development foreground of power system transient stability analysis is clarified.It is pointed out that the wavelet analysis used in the transient stability analysis has a broad space for development,especially in the transient signal processing,it is a valuable research direction.
