Abstract:

配电网户外柱上无功补偿设备是配电线路重要的无功补偿手段,然而现在大多柱上无功补偿设备只能补偿安装点远端无功功率。无功优化规划的计算从原理上更认同配电线路中投入的电容器可以同时补偿其安装点前后的无功功率。针对上述问题,提出将无功补偿设备的补偿点和测量点分离,解决柱上无功补偿设备补偿范围受到局限的问题。为此提出补偿点与测量点分离的无功补偿设备的无功优化规划算法。采用灵敏度法确定补偿点位置,利用相同补偿功率下损耗最小的原则确定测量点位置。基于遗传算法求解系统的最优无功规划。通过算例的计算,验证此种无功优化规划算法可以有效地提高设备的利用率,改善无功补偿效果,获得更大的经济效益。
