High-reliability power supply method of converter valve controller

Abstract

The invention provides a high-reliability power supply method of a converter valve controller. A converter valve controller case in each converter valve control screen cabinet is provided with a powersupply module. The power supply module is independently arranged in a shell matched with the case. The power supply module is composed of a plurality of modular power supplies, and the power, the internal circuit, the boundary dimension and the interface of each modular power supply are completely the same. Two paths of direct-current power supplies are used for supplying power, and the module power supply can work normally under the condition that any path of direct-current power supply is electrified. A combinable modular power supply mode is provided by improving a power supply mode of anexisting converter valve controller, so that the problems of poor compatibility and complex production management of a power panel caused by different power requirements of the converter valve controller are solved, and the overall reliability of a power supply system is improved through multi-power-supply power supply.

Description

technical field [0001] The invention relates to a method in the field of flexible direct current transmission converter control, in particular to a highly reliable power supply method for a converter valve controller. Background technique [0002] The converter valve controller is the control center of the converter valve. It is responsible for controlling and monitoring the working status of each power unit on the valve tower to meet the dispatching requirements of the upper converter and station-level power system. In engineering applications such as flexible DC transmission, the converter, as a core component, affects the stability and reliability of the entire system, so the reliability of the working power supply of the converter controller is crucial to the system and engineering . [0003] At present, the converter valve controller has different configurations according to the actual application fields and application projects, but in form, many boards are inserted i...
