摘要
在简单分析电力系统电压稳定机理的基础上,应用无功-电压灵敏度指标查找电网电压薄弱区域的方法。应用天津电网数据进行算例分析,所得结果与该电网实际情况相符,说明了该方法的有效性和实用性,并且该方法具有简便易用的特点。最后分析了产生电网电压薄弱区域的原因并给出解决的相应措施,验证了所给措施的有效性。
On the basis of simply analyzing the power system voltage stability,this paper proposes a method to comprehensively search the voltage weak region for power grid.The method is based on sensitivity index,using the power grid data of Tianjin Network as an example.The results show it is consistent with the actual situation.Illustrates the effectiveness and practicality of the method,and the method is simple and easy to use.Finally,analyze the cause of voltage weak area produced and give the address to verify the effectiveness of the measures.
