Converter station valve cooling system inlet valve temperature prediction monitoring method and system

The invention discloses a converter station valve cooling system inlet valve temperature prediction monitoring method and system, and relates to the technical field of power system detection, and the method comprises the steps: obtaining a converter valve DC load rate P, a spraying water flow Ls, a cooling water flow Lf, a cooling tower air inlet amount Q, and an environment wet bulb temperature Tw; constructing an inlet valve temperature prediction model according to the obtained physical quantity; and monitoring the cooling tower heat exchange performance of the converter valve according to the established inlet valve temperature prediction model. Specific fault reasons are judged through the spraying water flow, the cooling water flow, the cooling tower air inlet amount and the environment wet bulb temperature, an alarm is given to remind an operator, and the operation reliability of the converter station valve cooling system is improved. 本发明公开了一种换流站阀冷却系统进阀温度预测监控方法及系统，涉及电力系统检测技术领域，方法包括获取换流阀直流负荷率P、喷淋水流量Ls、冷
