摘要：在变压器经济运行理论分析的基础上，计算出了35 kV典型变电站变压器经济运行点，对典型日负荷曲线和变电站负荷性质进行了分析，提出了一种变压器经济运行时段控制法，确切地给出变压器经济投切的时机，优化了变压器运行方式，同时不增加设备动作次数。运行实践表明该方法可有效降低变压器自身的综合功率损耗，具有较好的经济效益。

Abstract：This paper calculates the economic operation point of35 kV typical subst~ion and analyzes typical daily load curve based on the analysis of theoretical of transformer economic operation．The time—interval control method is presented．And ultimately the optimal switch—ordofftime is determined，transform er’S operating mode is optimized，and actions times ofequipment is not increased at the same time． Operation practice shows that the method can effectively reduce the transform er’S complex power loss，with beaer
econom ic benefits．
Key words： transform er； econom ic operation； time—interval control method； substation； practice
