摘　　要：随着现代电力系统所涉及的自动控制、电力电子技术方面大功率负荷的日益增多,负荷特性多表现为功率形式从而使负荷特性呈现出与早期电力系统阻抗型负荷或电压源型负荷所不同的特点。运用交流电路运行基本规律,分析了功率型负荷的运行特性,指出对于功率型负荷,采用传统的调节送端电压以稳定受端电压的常规控制方式可能导致受端电压失稳。讨论了在不同负荷特性下,如何维持受端电压稳定。With the increasing of power type load which concerns the aspects of automation control and power electronic in modem power system, characteristics for load are in the form of power, and different characteristics are shown to compare with impedance type load and voltage source type load in early power system. The characteristics of power type load is analyzed by basic operating law for alternating current circuit and it is pointed that taking traditional regulating voltage mode that adjusts sending end voltage to stabilize accepting end voltage may result in the accepting end voltage instable. How to maintain the accepting end voltage stable in different type load is discussed.
