Description

Technical Field

[0001] The present invention relates to the technical field of relay protection for electric power systems, and in particular to a method and system for self-describing modeling of physical information of intelligent relay protection equipment. Background Art

[0002] In recent years, the exploration of relay protection informatization carried out in the industry has all been based on standardization on the original basis. The underlying information architecture and transmission mode of relay protection have not changed, and it still relies heavily on manual configuration of master and substations, making it difficult to solve the needs of rapid iteration of information intelligent perception and application under equipment changes such as renovation and expansion. It is necessary to study the goal of intelligence and build an intelligent relay protection "operating system" to comprehensively improve the level of relay protection information sharing and information security, meet the requirements of efficient construction, efficient operation and maintenance, and flexible adaptation, and achieve the optimal cost and performance of power grid equipment over the entire life cycle.

[0003] Both domestic grids have conducted research on the intelligent operation and maintenance functions of relay protection based on the collection of rich data resources provided by intelligent secondary devices. For example, the State Grid Corporation of China has begun to promote the application of intelligent recorders to carry out intelligent operation and maintenance and inspection of protection equipment. However, the functional configuration of the intelligent operation and maintenance function itself still requires a lot of manual participation, which makes it difficult to solve the intelligent perception of information under changing status of equipment such as renovation and expansion, and the rapid iteration requirements of applications. It is also impossible to solve the efficient construction and management requirements of equipment status perception, setting, and application from the bottom up.

Professional management such as equipment status perception, setting, and application rely on manual work.
