Study on Thermal Performance Evaluation Method of Spray Water System of Valve-cooling in Converter Station

针对换流站缺乏评估阀冷外冷水系统热力性能有效方法的问题,研究闭式冷却塔数学模型及其求解方法,分析运行参数对冷却塔热力性能的影响,提出一种多判据的阀冷外冷水系统热力性能评估方法,并说明阀冷外冷水系统热力性能监测系统的硬件构架。

For the lack of thermal performance evaluation method of spray water system of valve-cooling in converter station,the mathematical model for closed cooling tower and its solving method were studied. The effect of operation parameters on the cooling tower thermal performance was analyzed. A multi-criteria method for evaluating the thermal performance of spray water system was proposed and the hardware framework of the thermodynamic performance monitoring system for spray water system of valve-cooling was introduced.
