Abstract

The present invention relates to a redundancy control system and method suitable for direct current transmission, and a management control device. The management control device comprises a control unit, a trigger / return check optical module and at least two communication modules. The trigger / return check optical module is used for connecting power electronic switches. Each communication module isused for connecting a valve control unit and a redundancy management control device. The control unit has a selection function, and can select the correct and fastest trigger signal from trigger signals from different communication channels. The system includes the valve control unit, at least two of the above-described management control devices, and the power electronic switches coupled to eachof the management control devices. The method monitors communication channels of trigger signals received by the control units of the power electronic switches, and timely selects the first-received correct trigger signal as a trigger instruction to be output according to the reception completion flag bit and the communication check bit. The invention improves the stability of the system operation, the control reliability and the error correction capability of the system.

Description

technical field [0001] The invention belongs to the technical field of flexible direct current transmission, and in particular relates to a redundant control system, method and management control device suitable for direct current transmission. Background technique [0002] The utilization ratio of new renewable energy such as wind energy and solar energy is constantly increasing, and high-voltage direct current transmission technology has also been widely used, especially flexible direct current transmission technology, which can realize multi-point collection of energy, efficient use of energy and flexible consumption of energy. At the same time, the development and application of high-voltage DC circuit breakers have also received great attention. [0003] The flexible direct current transmission system can realize the stable operation of the power grid under the network, island or weak system. As a new generation of DC transmission technology, flexible DC transmission i...
