摘要
电网利用效率与电网经济性密切相关,日益受到关注。从电网年最大负荷利用率、主变容量利用率、线路容量利用率、土地利用效率4个方面提出有关电网利用效率的指标,阐明指标的定义及计算方法,推导出指标取值的合理范围。以华东500 kV电网为例,对效率指标进行分析。首次系统阐述了电网利用效率的概念,对推进电网精益化管理具有重要意义。
Greater importance has been attached to the close correlation between power grid efficiency and economy.This study presents power grid utilization efficiency indices in four domains： the maximum annual load,the transformer capacity,line capacity and land.Their definitions and calculation methods are formulated and reasonable range of values are derived.Finally,the case of 500kV East China power grid examplifies the efficiency indices.To sum up,the systematically expounded concept of power efficiency in this research can be significant in the promotion of the grid lean management level.
