摘要
电压波动与闪变是电力系统中一种常见的电能质量问题。正确识别供电系统中的闪变源,有利于闪变责任划分,调节供、用电双方矛盾。为此,本文以电压波动与闪变形成原因为切入点,重点对基于波动潮流方向的定位法、基于电压电流间内在联系的定位法、基于波动强度的定位法和其他定位法进行深入讨论,并详细分析各种方法的原理和优缺点,提出了闪变源定位的关键问题。最后对闪变源定位方法做出总结,并对今后的研究方向提出建议。
Voltage fluctuation and flicker is a common power quality problem in power system,and the correct identifi. cation of a flicker source in a power supply system is helpful for responsibility division and the contradiction regulation between the power supplier and users. In this paper,starting with the cause analysis of voltage fluctuation and flicker, the source location methods including those based on the direction of fluctuating power flow,the interconnection be. tween voltage and current,and the fluctuation intensity,respectively,as well as other methods,are discussed in depth. Moreover,their principles,advantages,and disadvantages are analyzed in detail,and the key problems with flicker source location are pointed out. Finally,the methods for flicker source location are summarized,and suggestions on the future research are given.
