本文介绍了中国电力工业的发展、中国区域电网联网的现状、环境影响和潜在效益。中国的发电厂主要是火力发电厂，燃烧化石燃料，特别是煤炭，排放大量的污染物和温室气体，如二氧化硫、氮氧化物和二氧化碳。中国在二氧化硫、二氧化碳排放量方面领先于其他所有国家，电力行业是这些排放的最大贡献者。通过区域电网互联可以带来许多环境效益。也就是说，将避免建设小型发电能力；将自然资源用于区域规模的发电；发电来源可以与用电中心分开，这将减少污染物和温室气体的排放，并有助于减少人类暴露在空气污染物浓度升高的环境中。因此，逐步扩大电网，实现电网互联互通，应该是中国电力系统发展大格局的一部分。
This paper describes the development of China's power industry, present situation, environmental influences and potential benefits of regional power grid interconnections in China. Power plants in China are mainly thermal, burning fossil fuels especially coal which emit a great deal of pollutants and greenhouse gases such as SO2, NOxand CO2. China leads all other countries in emissions of SO2, CO2, and the power industry is the largest contributor to these emissions. There are a number of environmental benefits through regional power grid interconnection. That is, the construction of small electricity generation capacity would be avoided; natural resources would be used to generate electricity on a regional scale; and generating sources can be separated from centers of electricity use, which will decrease emission of pollutants and greenhouse gases and help to reduce human exposure to elevated air pollutant concentrations. Therefore, gradually enlarged power grids, and power grid interconnection, should be part of the general pattern of power system development in China.
