摘要
为有效寻找电网无功补偿配置的薄弱点,提出了一种新的无功补偿设备优化配置的方法。该方法根据110kV变电站全年的无功负荷情况统计出无功负荷概率分布曲线,采用最优覆盖法建立无功补偿配置优化模型,并通过全局搜索寻求优化配置方案。通过对优化配置方案与实际补偿容量配置的比较,给出了无功补偿配置相对薄弱的变电站,为电力系统规划人员提供决策依据。
To find the weak points of power system reactive power compensation allocation,this paper presents an optimized configuration of the method,which gathers reactive power loads of 110 kV substation throughout the year to get the optimal probability curve,adopts optimal cover method to establish the optimized configuration model,and uses global search to find the optimal solution.Through the comparison between the optimized configuation scheme and the actual compensation capacity,this paper presents the substation with insufficient reactive power compensation allocation,which supplies effective recommendations for the power system planners.
