摘　　要：简述了电网无功电压综合控制的必要性,根据电力系统实际运行情况及模拟退火(SA)算法自身的特点,就编码方式、状态产生函数、状态接收函数、初温、温度更新函数以及内、外循环终止准则等主要问题提出了改进SA算法。通过IEEE标准系统的仿真,说明改进SA算法具有搜索效率较高,原理及实现简单,速度快等优点。The necessity of VAR and voltage control of power system is briefly introduced. An improved SA algorithm is proposed based on operational practice and the characteristics of SA. Major problems such as coding modes, generating functions, accepting functions, initial temperature, temperature updating functions as well as the terminating conditions of inner and outer cycle are also taken into consideration. The improved SA algorithm proved to be of higher efficiency, easier principles and realization, faster speed via the test in IEEE standard network.
