确定电网电压薄弱区域分析方法研究

Research on determining the weak voltage area of grid

在分析电力系统电压稳定机理的基础上,提出了一种应用有功裕度指标、灵敏度指标、电压裕度指标及全网N-1电压扫描综合查找电网电压薄弱区域的方法。应用北京电网夏季高峰数据文件进行算例分析,所得结果与该电网实际运行情况相符。该方法具有系统性、简便易用的特点,具有很好的工程实用参考价值。

This paper proposes an application of voltage stability,active margin,sensitivity,active margin and the N-1 voltage scanning of the whole network to look for voltage weak area comprehensively,based on the analysis of power system voltage stability mechanism.Take the year 2007 summer peak data of Beijing grid for example,the results show that the method has the features of effectiveness systematic,easy-to-use,and good practical reference work.
