| 摘 要： | 对削峰填谷能降低变压器的电能损耗进行了理论分析,得出了变压器节约电量的计算式,并进一步得出变压器的理想躲峰负载系数。削峰填谷不仅能减少变压器的有功损耗,还能减少无功损耗,对用电企业会产生较好的经济效益,同时对电网的经济运行也具有重要意义。算例进一步表明,削峰填谷能使用电企业每年节约大量电费。

| Abstract: | The power loss of transformer which can be reduced by peak load shifting is analyzed theoretically in this paper.The formula of saving power and the ideal load coefficient to avoid peak are also derived.Peak load shifting not only can reduce the active power loss,but also can reduce the reactive power loss.It gives better economic returns and is important to economic operation of power system.Example further indicates that peak load shifting can save a great deal of electricity charge annually for the elect... |
