Temperature Control Technology for Valve Cooling System of Air-cooled Electrical Power Converter
During the operation of the HVDC transmission system,the converter valve may generate much heat,which can affect the safety and stability of system operation.In order to effectively control the working temperature of the air-cooled converter valve,PID temperature regulating strategy is proposed based on a deep analysis of the working principle and thermal characteristics of the cooling system.According to the temperature control requirements of the cooling system,digital simulation verification and performance analysis are carried out.The results show that the practical technology based on PID temperature control can effectively meet the temperature control characteristics of the cooling system,and achieve high stability and control accuracy.
