Abstract

A converter valve on-line monitoring device provided by the present invention comprises a control chip, and a monitoring circuit, a communication return circuit and a trigger circuit which are connected with the control chip, the monitoring circuit is used for monitoring the operation state of a target converter valve and sending the operation state to the control chip; the control chip is used for performing logical operation on the running state, sending the running state after logical operation to the valve-based electronic equipment through the communication return circuit, receiving a control instruction sent by the valve-based electronic equipment through the communication return circuit, generating a corresponding control signal according to the control instruction, and sending the control signal to the trigger circuit; and the trigger circuit is used for controlling the target converter valve to act according to the control signal. The monitoring circuit monitors the operation state of the target converter valve and sends the operation state to the valve base electronic equipment, so that an operator can monitor the operation state of the extra-high voltage converter valve in real time and position a fault point in time, and the operation of the extra-high voltage converter station is more intelligent.

Description

technical field [0001] The invention relates to the technical field of direct current transmission, in particular to an online monitoring device for a converter valve. Background technique [0002] At present, UHV DC transmission is a key technology for the implementation of the "West to East Power Transmission" strategy. It has the advantages of low transmission loss and small corridor width, and can realize ultra-long-distance and ultra-large-capacity power transmission. As the core equipment of the UHV DC transmission system, the UHV converter valve can directly affect the operation reliability of the DC transmission system whether it can work normally. Therefore, how to timely, comprehensively and accurately monitor the operating status of UHV converter valves and effectively predict potential failure risks has become a key factor to ensure the reliable operation of DC transmission systems. Contents of the invention [0003] Therefore, the technical problem to be solv...
