分析了电压序列选择的基本要求，研究提出了电压序列可行的配置方案。结合我国电网发展现状，论述了我国电网电压序列优化选择的重点。在此基础上，从技术、经济、社会等方面提出了电压序列评价指标，并进一步建立了可用于指导实际工作的评价指标体系。

By analyzing the basic requirements for selecting voltage sequence, every possible configuration of voltage sequence is presented. Combined with development status of China’s power grid, the emphasis on optimization and selection of voltage sequence is discussed. On this basis, evaluation indexes of voltage sequence are proposed from technical, economic, social and other aspects. The evaluation index system is further established to guide selection of voltage sequence.
