中文摘要：

分布式能源站以冷热电联产技术为基础，在并网发电的同时，直接向负荷区用户提供制冷、供热服务。在分析分布式能源站发展现状的基础上，综合比较了分布式能源站与火力发电厂在资源利用、污染物排放、清洁生产等方面的优势，并利用AERMOD模式预测了天津某分布式能源站对区域大气环境的影响。预测结果表明SO2、NO2等污染物占标率很低，分布式能源站具有很好的环境效益。

英文摘要：

On the basis of combined cooling, heating and power technology, distributed energy stations generate electricity and provide users with refrigeration, heating at the same time. The development of distributed energy stations was discussed, and the advantages of distributed energy stations in resource utilization, pollutant emission, clean production, etc, were compared with the conditions of thermal power plants. The impact of distributed energy stations of Tianjin on the regional atmospheric environment was predicted with AERMOD model, the prediction results showed that their SO2, NO2 and other pollutants accounted for the standard rate were very low. The distributed energy stations had good environmental benefits.
