摘　　要：无功运行优化问题的关键在于获得最优解或较好的次优解。传统的线性规划法和非线性规划法不能很好地处理整型变量问题,而常规模拟退火算法(SA)的鲁棒性不高。结合高中压配电网的特点,对SA进行了改进:采用记忆指导搜索方法,并采用模式法修正局部最优解。数值对比试验表明,本方法是合理的和可行的,具有一定的实用意义。The key to the optimization of reactive power operation is to get optimum value or satisfactory quasi-optimum value. Traditional methods of linear programming and non-linear programming cannot deal with the problem of integral variable successfully, and the simulated annealing algorithm(SA) is not very robust. Concerning the characteristics of high-medium voltage distribution system, the SA is modified as follows: using remembrance-guided search method, and modifying the quasi-optimum value with pattern search method. Numerical experiment demonstrates that the above method is reasonable, feasible, and practical to some extent.
