摘　　要：提出了利用向量场正规形方法分析电力系统在不同运行条件下的非线性行为,以非线性参与因子衡量节点对静态电压稳定性的重要程度,并以此确定电力系统中无功补偿设备的有效安装位置。在New England 39节点系统上进行了算例分析,验证了该方法的正确性和有效性。In this paper it is proposed to analyze nonlinear behavior of power system under different operating conditions by use of the approach of normal form of vector field. The nonlinear participation factor is used to weigh the importance of nodes to steady state voltage stability. Case study of the proposed method is conducted by New England 39-bus system, the results show that comparing with linear analysis methods the normal form method can reflect the nonlinear characteristic of power system better; by use of the proposed method the weights of nodes to steady state voltage stability under strong nonliearity can be effectively analyzed, on this basis the location where reactive power compensation devices should be installed is effectively determined.
