Abstract

The invention relates to a high-voltage direct-current transmission converter valve control device and a converter valve, and belongs to the high-voltage direct-current transmission technology field. An information collection unit is arranged in a converter valve system additionally, and information of all the converter valve monitoring modules is gathered and processed through the information collection unit, and then is uploaded to a pole control system. A received control command sent by the pole control system is subjected to copy and expansion and then is sent to each monitoring module, and consistency and reliability of command sending of the pole control system are ensured. Information interaction between valve control and pole control is achieved through the information collection unit, valve control and pole control interfaces are simplified, the valve control information processing function is determined, thus the valve control system function is independent relatively, and valve control system standard design and modularized expansion are convenient.

Description

technical field [0001] The invention relates to a high-voltage direct current transmission converter valve control device and a converter valve, belonging to the technical field of high-voltage direct current transmission. Background technique [0002] The converter valve control system in the UHV DC transmission project is the interface device between the extreme control system and the converter valve. The main function is to receive control commands from the extreme control system, monitor and control the converter valve and its auxiliary equipment, and feed back the monitoring information and control status to the extreme control system. The pole control and the valve control are connected through the communication bus and the signal line for information exchange. [0003] The converter valve control system is equipped with corresponding converter valve monitoring modules according to different types of converter valves in specific projects. In the prior art, the conver...
