摘　　要：随着电力系统的运行越来越接近其极限状态,电力系统电压稳定问题日益突出,研究一种精确可靠的电压稳定分析方法是非常必要的。提出了一种基于动态响应的电压稳定分析方法,该方法通过计算戴维南等值参数及确定电压稳定判据可以精确实现电压稳定分析。IEEE 9节点算例仿真验证了该方法的正确性和有效性。当在线分析成为趋势的时候,该方法对实现电压稳定的在线分析有一定的现实意义。As modem power system is pushed to the maximum operation condition, system vohage stability becomes a significant issue. It is necessary to find out a precise and reliable method to analyze voltage stability. This paper presents a method which is based on the dynamic response theory. This method can analyze stability accurately by calculating Thevenin equivalent parameters and judging the status of voltage stability. The outcomes of IEEE 9-bus power system simulation have confirmed the validity and effectiveness of the method. Under the trend of on-line analysis, this method is of certain significance to on line analysis of voltage stability.
