Abstract
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...
