直流换流站阀冷系统及其控制方法
摘要：
本发明公开了一种直流换流站阀冷系统包括阀冷单元、生产给水单元及阀冷控制单元，阀冷控制单元分别连接于阀冷单元及生产给水单元，阀冷控制单元用于对阀冷单元进行流量检测，并发送流量控制信号，生产给水单元分别接收流量控制信号，并控制生产给水单元分级出力；其中，当生产给水单元未接收到流量控制信号，生产给水单元停止出力。当换流阀启动时，发出流量控制信号，即可启动生产给水泵，未收到流量控制信号自动停止生产给水泵，避免因压力传感器故障，导致生产给水单元异常启动或停运，导致水管爆裂或直流闭锁的问题。还提供一种直流换流站阀冷系统的控制方法。
摘要（英）：

The invention discloses a director current convertor station valve cooling system. The director current convertor station valve cooling system comprises a valve cooling unit, a production water supply unit and a valve cooling control unit. The valve cooling control unit is connected with the valve cooling unit and the production water supply unit, the valve cooling control unit is used for conducting flow detection on the valve cooling unit and sending a flow control signal, and the production water supply unit receives the flow control signal and controls the production water supply unit for output in a classification mode. When the production water supply unit does not receive the flow control signal, the production water supply unit automatically stops output, when a converter valve is started, the flow control signal is sent, a production water supply pump can be started, and if the flow control signal is not received, the production water supply pump stops automatically, so that the problem that the production water supply starts abnormally or stops operating due to the breakdown of a pressure sensor, and then the problems that a water pipe bursts or direct current blocks are avoided. The invention further provides a control method of the direct current convertor station cooling system.
