Abstract As the critical thermal management component in high-voltage direct current (HVDC) transmission systems, the reliability of the valve cooling system directly affects the service life and transmission capacity of the converter valves. This paper proposes a temperature control method for valve cooling system to address the problem of DC power drop caused by excessive temperature difference between inlet and outlet valves due to frequent start-stop cycles of air coolers caused by improper switching strategy of external air coolers. The effectiveness of the proposed method is verified through simulation results and engineering case analysis of the external air cooler’s switching strategy.
