针对电容器的优化分组提出了典型日负荷曲线与经济性分析相结合的电容器优化分组方法。该方法以电容器投资费用与因变电站的无功补偿不足而引起的系统有功损耗费用之和达到最小为优化问题的目标函数,并以此为基础求解电容器的优化分组问题。对实际电力系统电容器分组优化改造的结果表明,以本文提出的优化目标函数为基础的方法具有明显的经济效益,可以提高供电质量和设备的利用率。
Aiming at the optimal grouping of capacitors, a method of capacitor grouping optimization combining with typical daily load curve and economic analysis is proposed. This method minimizes the sum of the cost of system active loss caused by the capacitor investment cost and the reactive power compensation of the substation as the objective function of the optimization problem and solves the problem of the optimal grouping of capacitors based on this. The results show that the method based on the optimization objective function proposed in this paper has significant economic benefits and can improve the quality of power supply and equipment utilization.
