摘　　要：换流站阀冷却系统用于换流阀冷却降温,由于格尔木高海拔因素和日夜温差变化,阀冷却系统应防止结温过高导致换流阀晶闸管击穿。通过分析柴达木换流站阀冷却系统控制过程和运行工况,判断其是否符合设计要求,能否满足降温需求。The converter valve cooling system is used to cool down the converter valve. Because the high altitude and big difference between day and night temperatures in the Gemuld area,the cooling system must meet the requirement to prevent the breakout of the converter valve ＇s thyristor result by high junction temperature. The control and operation of the cooling system are analyzed in this paper to estimate whether the cooling system meet the design and cooling requirement.
