Description

technical field [0001] The invention belongs to the field of power system simulation training, and in particular relates to a method for modeling secondary equipment of an intelligent substation for a simulation training system. Background technique [0002] With the rapid development of smart grid construction and technology, traditional substations have been gradually replaced by smart substations, which have become an important support for smart grids. Smart substations have adopted a large number of new technologies and new equipment. Compared with traditional substations, the system operation and maintenance of smart substations has undergone major changes. The development of smart substation simulation training systems is used to train operation and maintenance personnel to improve the skills of operation and maintenance personnel. Levels become an important means of daily training. [0003] Smart substation simulation requires the establishment of detailed logic mode...

AI Technical Summary

Problems solved by technology

[0003] Smart substation simulation needs to establish detailed logical models, equipment models and 3D models of secondary equipment. At present, the modeling of secondary equipment is still implemented manually, that is, through manual photography, on-site data collection and research, etc., to obtain Information such as the type and quantity of the secondary equipment configured in the smart substation, the attached primary equipment, and the connection relationship between the secondary equipment are used to compile relevant model files for the secondary equipment and establish a simulation model library. The disadvantages are: 1. Difficulty in data collection, Problems such as unclear device associations can easily lead to model errors; 2. There are problems with heavy workload and low modeling efficiency; 3. It is difficult to establish a topology model for information interaction between secondary devices
