| 摘 要： | 对两台三绕组电力变压器的并列运行,单独运行时变压器有功功率损耗随负我的变化情况进行了深入讨论,同时对电压的影响作了全面比较,得到两台电力变压器并列运行与单独运行的经济临界负荷S.并以乐山电业局城区供电局220 kV范坝变电站为实例进行了计算论证,针对性地提出不同负荷电压下该站电力变压器经济运行方案.

| Abstract: | The active - power losses changing with load are discussed thoroughly when two three - winding power transformers in parallel operation or in isolated operation, at the same time the impacts on voltage are compared completely, so that the economic critical load S in parallel operation and isolated operation of two power transformers are obtained. Taking 220 kV Fanba Substation of Leshan Urban Power Supply Bureau for example, the calculations are carried out, and specifically the economic operation scheme is proposed for power transformer of that substation under different load voltage. |
