一、引言 我国电厂和电网设施不相协调,输变电能力和发电能力极不相称,线损率高达8.2％,比国际上高1/3。电力系统总功耗占总发电量的30％,变压器总功耗占电力系统总功耗的1/3,因此变压器总功耗占总发电量的10％。七五期间变压器与发电机容量配比为11.4:1。电力系统发电、输运、配电和用电四个环节中,从发电到用电要经过3～4次
I. Introduction China’s power plants and power grid facilities are not coordinated, power transmission capacity and power generation capacity disproportionately, the line loss rate as high as 8.2%, higher than the international one-third. The total power consumption of the power system accounts for 30% of the total generating capacity. The total power consumption of the transformer accounts for 1/3 of the total power consumption of the power system, so the total power consumption of the transformer accounts for 10% of the total generating capacity. During the seventh five-year period the transformer and generator capacity ratio of 11.4: 1. Power generation, transportation, distribution and electricity in four links, from power generation to electricity to go through 3 to 4 times
