摘　　要：合理的无功就地补偿和选择变压器容量可以降低损耗、提高系统运行的经济性,是电力需求侧管理的重要内容。将二者有效结合,推导最经济运行公式,通过简单迭代来确定无功就地补偿容量和变压器容量的选择,并运用算例实例证明其应用效果。The reasonable wattless power compensation and transformer capacity selection can reduce the loss, and improve the efficiency of system operation, which is an important content of power demand side management. The effective combination of the two formulae leads to an economical operation pattern, through simple iteration to determine reactive compensation capacity and the transformer capacity selection, and the use of examples has demonstrated its application effect.
