摘　　要：文章以某发电厂二期工程为例对600MW空冷机组厂用电电压等级和高压厂用电变压器阻抗的选择进行了讨论,对给水泵采用软起动的可行性进行了分析,并对高压厂用电系统采用6kV的方案与常规方案进行了投资比较。文章认为,该发电厂二期工程的600MW空冷机组厂用电电压等级选用6kV电压是完全可行的。The article,with the phase Ⅱ project of one power plant as an example,discusses The voltage class of service power and the selection of impedance of high voltage service power transformer for 600 MW air cooling unit aria lyzes the feasibility of soft start - up of feedwater pnmp,and condncts the investment comparison of 6 kV scheme and conventional scheme for high voltage service power system. The article thinks that,to adopt 6 kV voltage as the service power voltage class for 600 MW ak cooling unit of phase Ⅱ project of this power plant is quite feasible.
