摘　　要：文章以国内发电厂工程为依托,对600MW空冷机组厂用电电压等级的选择进行初步的探讨,从设计和工程实际出发进行了论证,推荐采用10kV和6kV两种电压等级并存的厂用电中压系统。论述过程中充分的引用了我国现有的规程和标准,并遵循技术先进、经济合理、安全可靠的工程设计原则,得出了适应国情的方案。This paper preliminarily discusses the voltage grade option of HV service power for 600 MW air-cooling unit based on the domestic projects of power plant. The medium voltage system of service power with the two coexist voltage grades of 10 kV and 6 kV is recommended, which is verified from design and project reality. The existing standards and rules in China, and design principles with advanced technology, economic and reliable safety are quoted in the verification, and the scheme that meets national conditions is given.
