摘要
文章针对220kV变电站中三绕组变压器的经济容量优选问题,进行了专门论述和举例分析。提出在增大变压器基础容量的基础上,通过对运行的节电降耗经济性方面的计算比较,计算出追加投资的回收期,并计算出企业节电的经济效益和社会效益,从而进行综合性经济评价,合理确定出变压器的最佳经济容量选择的方法。
According to the optimal selection problem of economic capacity for three-winding transformer in 220kV substation, special exposition and examples were analyzed. Based on increasing transformer basic capacity, and through the calculation of electricity saving and pay back period for the addition investment, the social and economy benefits of electricity saving for enterprise are calculated, and comprehensive economic evaluation, the method of determining the best economic capacity option for transformer reasonably are put forward.
