柔性直流换流站阀厅设备温度监测

换流阀是直流输电系统的核心设备，阀厅设备温度监测对于保证换流阀的安全正常运行具有重要意义。以±200 kV舟山多端柔性直流输电工程为背景，阐述换流站阀厅的结构及阀厅设备特点，提出3种阀厅设备测温方案（红外测温、光纤测温、无线测温），通过技术安全比较，得出红外测温方案不影响阀体结构，且能满足监测要求，该文推荐柔性直流阀厅设备测温采用红外测温方式。

Temperature Monitoring of Valve Hall Equipment in Flexible DC Converter Station

The converter valve is the core equipment in DC power transmission system, and the temperature monitoring of valve hall equipment is of great significance to guarantee the safe operation of converter valve. Based on ± 200 kV multiterminal-flexible DC transmission project in Zhoushan, the structure of valve hall in converter station and the characteristics of valve hall equipment are described, and three kinds of temperature measurement schemes for valve hall equipment: infrared, optical and wireless are proposed. Finally, through a comparison of technology and safety, the infrared temperature measurement scheme is presented that could satisfy the monitoring requirements without affecting the structure of valve body. It is suggested that the temperature measurement of flexible DC valve hall equipment should apply infrared method.
