摘要
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。
Based on the daily load curve and economy analysis, an optimization grouping method for parallel capacitor banks is proposed. The target of the method is to minimize the aggregate of the capacitor cost and the cost of power loss due to inadequate reactive compensation of the substation, and the optimal grouping problem for capacitors is studied based on that. Practice shows that the method is effective and can be used to improve the utilization rate of power supply equipment.
