摘　　要：无功电源优化规划的目的是通过对无功补偿点的最佳位置和最佳无功补偿容量的优化,保证电力系统的安全经济运行、电压稳定、减少网损、降低投资。文中提出两阶段优化规划的思想,即运用灵敏度分析法确定系统的无功电源的补偿点,应用改进模拟树木生长算法求解无功电源的补偿容量,二者交互进行,达到总体最优。某工业用户供电系统的优化结果表明该方法是可行和有效的。The purpose of reactive power supply program is to insure safe and economic operation of the power system, stabilize voltage, reduce loss and decrease investment by determing the optimal locations of the reactive power compensation and calculating the optimal reactive power compensation capacities of each reactive power compensate nodes. A method of two stages-optimal planning is proposed. It uses sensitivity analysis to ascertain the place of reactive power compensation at first and applies Plant growth simulation algorithm （PGSA） to solve the capacity of reactive power supply, and they interact each other, and then reaches the best. The result of calculation and analysis of a factory enterprise power system shows that the proposed method is feasible and effective.
