发电厂汽轮机热力性能试验期间系统隔离的重要性

Importance of System Isolation During Thermal Performance Test of Steam Turbine in Power Plant

文中以某电厂汽轮机热力性能试验为例,对在试验期间由于阀门内漏,致使计算求得的热耗率数据出现异常进行了分析,说明了系统隔离的重要性。

Taking a thermal performance test of a steam turbine in a power plant as an example,this paper analyzes the abnormality of the calculated heat rate data due to valve internal leakage during the test,and illustrates the importance of system isolation.
