本文讲述一起基于丝绸之路沿线国家落成的水电站,在工程电气设计时额外配置柴油发电机组容量的选择,包括事故紧急状态下的厂用电运行方式、负荷统计和起动压降校验的过程,并得出类似境外水电站总承包工程柴油发电机选型方法的结论。 This paper describes the selection of additional capacity of diesel generating units based on the hydropower stations completed in the countries along the Silk Road during the electrical design of the project, including the operation mode of plant electricity in emergency, load statistics and start-up pressure drop verification process, The conclusion is drawn that the diesel generator selection method of the general contracting project of overseas hydropower station is similar.
