摘　　要：针对小浪底水电站浑水发电时期技术供水清水水量不足的问题,提出了机组和主变清水串联供水方式,将冷却机组后的清水再供主变冷却使用,并通过两次真机试验检验了这种供水方式的应用效果。结果表明:这种方式可大幅降低浑水发电时期的清水用水量,节水效果显著,机组和主变冷却效果不受影响。During the power generation period with muddy water in Xiaolangdi Hydropower Station,clear water is insufficient for the technical water supply system.Thus,a series clear water supply mode of the units and main transformers is proposed.After the unit is cooled by clear water,the clear water is reused for the main transformer cooling.The practical performance of the proposed mode is verified by two real machine tests.The results show that the series clear water supply mode can significantly reduce the clear water usage during the power generation period with muddy water,while the cooling effect of the units and main transformers is not affected.
