在IEC41-1991规程允许的范围内,根据电厂的水头特点,天荒坪抽水蓄能有限责任公司、华东电力试验研究院与挪威水电专家合作,运用热力学的方法在天荒坪抽水蓄能电站5号机组上分别进行了泵工况和水轮机工况的热力学法效率测试。试验准确测量了高低压侧的温差,效率试验获得了良好的结果。就热力学的效率试验和分析方法进行了介绍。 In accordance with the rules of IEC41-1991, according to the head characteristics of the power plant, Tianhuangping Pumped Storage Co., Ltd. and East China Electric Power Experimental Research Institute, in cooperation with Norwegian hydropower experts, applied the thermodynamic method in Tianhuangping Pumped Storage Power Station 5 No. units were carried out on the pump conditions and turbine conditions of the thermodynamic efficiency test. The test accurately measured the temperature difference between the high and low pressure side and the efficiency test yielded good results. The thermodynamic efficiency test and analysis methods are introduced.
