摘要
本文中作者分析了某电网企业典型配电变压器能效提升方案的节能降损效果、成本及收益情况,并与常规改造方案进行对比,发现变压器能效提升方案较改造前方案具备一定的经济性,但较常规改造方案存在年平均负载率的经济临界点,且不同类型变压器的临界点存在较大差异,本文能够为结合变压器规格和年平均负载率合理确定经济最优的改造方案提供参考。
The energy-saving and loss-reducing effects,costs and benefits of a typical distribution transformer energy efficiency improvement scheme for a power grid enterprise are analyzed and compared with conventional transformation schemes.It is found that the transformer energy efficiency improvement scheme has a certain economy compared with the pre-transformation scheme,but there is an economic critical point of the annual average load rate compared with the conventional reconstruction scheme,and the critical point of different types of transformers is quite different.This paper can provide a reference for reasonably determining the most economically optimal reconstruction scheme based on transformer specifications and annual average load ratio rates.
