Abstract

The invention belongs to the technical field of power system control, particularly relating to a monitoring system applied to a high-voltage sub-module test on power electronic equipment. The monitoring system comprises primary equipment, a valve base controller and a human-computer interface management module, wherein the primary equipment comprises a direct current (DC) power supply, two high-voltage sub-modules and an inductor; the valve base controller is in charge of communication between the valve base controller and the high-voltage sub-modules and is capable of realizing the communication between the valve base controller and the monitoring system simultaneously; the monitoring system is in charge of completing the communication between the monitoring system and the valve base controller and completing the monitoring and control on a high-voltage sub-module test system; and the monitoring system is composed of a controller and an upper computer. The monitoring system provided by the invention can effectively meet the test control operation and monitoring function of the high-voltage sub-module test of a flexible DC power transmission system in a multimedia card (MMC) mode.

Description

technical field [0001] The invention belongs to the technical field of power system control, and in particular relates to a monitoring system applied to high-voltage sub-module tests of power electronic devices. Background technique [0002] In order to test the high-voltage sub-module of the MMC flexible DC transmission device, it is necessary to conduct sufficient tests on the high-voltage module. The test device evaluates the high-voltage sub-module through a series of tests to verify whether the design of the high-voltage module is qualified and applicable to the project. sex. The test monitoring system of the present invention provides test control and monitoring functions for the high-voltage sub-module test device. At present, there is no monitoring system for this kind of high-voltage sub-module test in the prior art. Contents of the invention [0003] In order to realize the test control and monitoring functions of the high-voltage sub-module test device, the pr...
