摘　　要：分析负荷特性对复杂系统等值PV曲线的影响,认为负荷特性及电源出力增长规律影响PV曲线;并分析追踪PV曲线的计及负荷特性广义潮流直接迭代算法.仿真分析结果表明该算法无需增加附加方程,能方便地分析负荷特性对电压稳定的影响,计算效率高.PV curve influenced by load characteristics is analyzed in this paper. It is found that the load characteristics and the increase orderliness of power source output have great influence on the PV curve. A direct iteration algorithm for generalized power flow taking account of load characteristics is also investigated. Simulation results show that the algorithm doesn＇ t need additional equation, is convenience to analyze the load characteristics influence to voltage stability, and is with high efficiency.
