摘要
电力变压器作为电力系统电压变换的主要设备,被广泛应用于输电和配电领域。变压器容量的选择直接影响到电网的运行和投资。随着不可再生能源的减少以及国家能源结构的不断转型,电力系统及用电设备运行的经济性、节能性成为电力企业关注热点。通过分析影响变压器损耗及其经济运行的关键因素,分别计算了不同负载条件下不同型号变压器损耗及节能容量;从节能角度提出配电变压器选型新方法,为节能型配电网建设新增约束条件的同时,提供了配电变压器选型依据,有效地提高了设备利用率。
Power transformer as the main equipment of power system voltage change,is widely used in transmission and distribution,the selection of transformer capacity directly affect the power grid operation and investment. According as the decreasing of non-renewable energy and constant transformation of the country′s energy structure,power system and the efficiency of equipment operation,saving electricity become electric power enterprises focus on hot. In this paper,by analyzing the impact of economic operation of the transformer loss and its key factors,are calculated respectively under different load conditions,different types of transformer loss and energy saving capacity. From the perspective of energy saving distribution transformer selection is put forward a new method,new constraints for energy-saving distribution network construction at the same time,provide the distribution transformer selection basis,effectively improve the utilization rate of equipment.
