摘　　要：合理地选择无功补偿装置的安装地点对于提高电力系统电压稳定性有重要意义。针对传统的失稳模式参与因子选址方法的局限性,提出了一种基于节点注入功率空间中电压稳定极限曲面的法向量指标用于无功补偿选址,并通过理论分析证明了法向量指标指导无功补偿的合理性。对IEEE39节点系统测试结果表明,与传统方法相比,法向量指标可以处理鞍结分岔和极限诱导分岔两类电压稳定临界点情况下的无功补偿选址,具有更大的适用范围。Proper reactive power compensation allocation is important to enhance the power system voltage stability. Based on the limitation of the traditional participation factor based allocation method, a normal vector index based on voltage stability limit surface is proposed to reactive power compensation allocation in this paper. The rationality of the index is proved. Simulation results on IEEE39 system have validated the correctness of the proposed index. Compare with the traditional method, the proposed index has a wider range of application since it can deal with the voltage stability critical point of saddle node bifurcation or limit induced bifurcation.
