Secondary visualization method based on extra-high voltage direct current transmission control protection device

Abstract

The invention discloses a secondary visualization method based on an extra-high voltage direct current transmission control protection device in the technical field of the electric system. A signal template list provided by a white-diagram/blue-diagram, protection control program and device factory is used as the foundation, the public information modeling is performed in allusion to a protection screen cabinet and attributes thereof respectively, and the model checking is designed on the basis of the model. The public information modeling part is capable of realizing the rational mapping from the public data model to the secondary system screen cabinet data of the extra-high voltage direct current transmission control protection device, and building the data linked list of the screen cabinet to the data object, and the multi-way tree data structure of the screen cabinet attributes. The software platform built by the method is capable of realizing the integration of a plurality of the factories of the secondary system of the extra-high voltage direct current transmission control protection device, solving the problems, such as the intersystem information transmission and the physical screen cabinet visualization, and reducing the difficulty of the operation, maintenance and repair of the extra-high voltage direct current transmission project.

Description

technical field [0001] The invention belongs to the field of ultra-high voltage power transmission, and belongs to the secondary system technology of electric power control and protection, and specifically relates to a secondary visualization method based on the control and protection system of ultra-high voltage direct current transmission. Background technique [0002] UHV DC transmission has the advantages of large transmission capacity, long distance, and low loss. It is an effective way to optimize energy allocation and an important measure to implement my country's "West to East Power Transmission" strategy. As the "brain" of the UHV DC transmission project, the control and protection system not only controls the entire process of AC and DC power conversion and DC power transmission, but also protects all electrical equipment in the converter station and DC transmission lines from damage caused by electrical faults. The functions of the DC control and protection system...
