Abstract

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.

Description

technical field [0001] The invention relates to the technical field of electric power system detection, in particular to a method and system for predicting and monitoring inlet valve temperature of a valve cooling system of a converter station. Background technique [0002] The converter valve is the core equipment for AC-DC power conversion in the converter station. The current-carrying components of the converter valve will generate a lot of heat during normal operation. Part of the heat generated is discharged to the outdoors by the cooling water circulation system, and the other part is passed through the natural convection and the valve. Hall air heat exchange. [0003] The cooling tower is an important heat exchange element of the cooling water circulation system. It cools the cooling water flowing out of the diverter valve, and then sends the cooled cooling water into the diverter valve to take away the heat. The heat transfer performance of the cooling tower is relat...
