Embodiment Construction

[0037] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0038] According to the topological structure of the primary system of the substation, the hierarchical design method is adopted to divide the overall centralized station domain protection function of the substation into multiple logical equipment modules according to the area, and each logical equipment module is subdivided into multiple protection logical function modules (lines) Protection module, transformer protection module, busbar protection module, etc.), the protection logic function module is composed of multiple mature and reliable basic function modules, without repeated design; finally, multiple logic equipment protection modules form the centralized substation domain protection of the substation as a whole. Each basic function m...

Abstract

The invention relates to a design method of a protection function of a centralized protection device of a transformer substation. The method comprises the following steps: (1), designing basic function modules; (2), combining the basic function modules into a protection module; (3), forming a logic equipment protection module; and (4), carrying out layered structure combination. According to the method, on the basis of the visual logic development environment, the modularized and structural protection function design is realized; the protection function realization is simplified; the work intensity is also reduced in the large-scale application; the protection transportability is high; and the reliability is also substantially enhanced.

Description

technical field [0001] The invention belongs to the field of relay protection in electric power systems, and relates to a method for designing protection functions of a centralized protection device. Background technique [0002] At present, the protection of substations is mostly distributed element protection, but this type of protection utilizes repeated and diverse information, and many identical or similar events are repeatedly processed between each element protection, thus wasting a lot of CPU resources and causing There are a series of problems such as large amount of operation and maintenance, long power outage time, and high cost. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a design method for realizing the protection function of the centralized protection device in the substation. Based on the visual logic development environment (VLD), the present invention adopts the des...
