换流站阀内冷系统与控制保护接口存在问题及措施

Existing Problems and Methods of Converter Valve Cooling System and Control Protective Interface

换流站阀内冷系统在换流站运行中起着非常重要的作用，对内冷系统运行参数、运行状态的监视显得尤为重要。以枫泾换流站为例，介绍了内冷系统与直流控制保护设备的接口配置情况，分析内冷系统存在的安全隐患主要为阀冷接口屏电源监视信号为单电源供电，可靠性不高，以及阀冷接口屏工控机电源设计接线等问题，提出相应的改进建议与措施。

Converter valve cooling system plays a very important role in a convertor station. So it is essential to monitor the parameter and status of the system. For example, in this paper, the cooling system in Fengjing convertor station and its links to the HVCD control equipment are introduced. The potential safety hazards are the electric source for the power supply monitoring of the interface screen is single, which is not reliable, and the problem with the design of the computer in the interface screen. Also the solutions are proposed.
