Study on Prediction Method of Inlet Temperature of Cooling Water in Valve Cooling System of Converter Station

针对换流站阀冷系统冷却塔换热性能难以评估的问题,研究直流负荷、喷淋水流量、冷却水流量、冷却塔进风量、环境湿球温度与冷却水进阀温度的关系。通过多元线性回归算法训练的模型,对冷却水进阀温度进行预测计算,并以此设计测量装置的故障检测逻辑。

Aiming at the problem that it is difficult to evaluate the heat transfer performance of cooling tower in valve cooling system of converter station,the relationship between DC load,cooling water flow,spray water flow,inlet air volume of cooling tower,ambient wet bulb temperature and inlet valve temperature of cooling water is studied.Through the model trained by multiple linear regression algorithm,the cooling water inlet valve temperature is predicted and calculated,and the fault detection logic of the measuring device is designed.
