摘　　要：负荷特性是影响电压稳定的最直接因素,对于研究电力系统的电压稳定性起着至关重要的作用.本文定性分析了静态和动态负荷特性与电压稳定之间的关系,阐述了电压失稳与电压崩溃的联系及其区别,并且指出电压失稳主要与负荷的动态电压特性相关.通过对简单电力系统进行仿真,验证了分析结果的正确性和有效性.随着电压稳定研究的深入,建立恰当的负荷模型将成为其走向成熟的关键.Load characteristics is the direct factor and plays a very important role in the power system voltage stability. The paper analyzes qualitatively the relationship between the static load characteristics, dynamic load characteristics and the voltage stability. That voltage instability and the voltage collapse are two different concepts are pointed out, and that the voltage instability is chiefly relevant to dynamic load characteristics is emphasized. The correctness and effectiveness of the analysis results are verified by the simulation for a simple power system. With the more research of the voltage stability, appropriate modeling of load will be crucial in practical voltage stability analysis.
