瞬变负荷对电力设备能耗的影响及消除

Affection of Instantaneous Changeable Load on Power Device Energy Loss and its Removal

由于我国经济的高速发展,电力短缺问题变得异常突出。据统计2003～2004年数省份出现了拉闸限电现象,缺电严重时上海的南京路也曾出现路灯和霓虹灯被迫关闭情况。为缓解电力供需矛盾,国家在加快电源建设的同时,还采取种种措施和手段提高终端用户电能使用效率。电网中瞬变功率对电磁设备的能耗有较大影响,通过分析电网中瞬变功率产生原因及对电能消耗的影响,然后采取有效措施,减少电网中瞬变功率导致的电能损失。

In addition to speed up power sources construction,some effective measures must be adopted to improve energy utilization at the end users in order to ease the contradiction between power supply and demand.The affection of instantaneous changeable power on electromagnetic device energy loss in the network is great.The cause and its affection on energy loss is analyzed,effective measures are adopted to reduce energy losses caused by instantaneous changeable power.
