风力发电是一种特殊的电力,由于风力的波动性,使电压稳定性成为风电系统面临的一个重要研究问题。为此,分析了国内外有关风电系统电压稳定性的研究现状和主要问题,阐明了风电与常规能源的区别,及其对电力系统电压稳定性的影响,主要从对电压稳定性影响的因素、含风电场的电力系统电压静、暂态电压稳定性的等值模型与分析方法、指标进行分析,并且提出改善风电系统电压稳定性的一些措施,最后指出分析中不足之处及以后需改善的方面。
Wind power generation is a special kind of power, due to the volatility of wind, voltage stability of wind power system becomes an important research issue. This paper focus on the present development status and major issues of voltage stability research in wind power systems both at home and aboard,clarifies the distinction between wind power and conventional energy and its impacts on power system voltage stability. This paper implements the research mainly from the influence factors of voltage stability, the equivalent models including the static and transient voltage stability of wind power system,analysis methods and indicators. Then some measures to improve the voltage stability for wind power system are offered,and the deficient aspects in the analysis and areas of improvement needed are pointed out.
