Power grid distributed intelligent safety and stability control system architecture method

Abstract

The invention belongs to the technical field of power systems, and particularly relates to a distributed intelligent security and stability control system architecture method. Based on a universal security and stability control system device communication network, flexible deployment and change of multiple sets of stability control systems and stability control strategies in a power grid are achieved, devices in the system can be deployed in multiple sets of systems executing different security and stability control strategies at the same time, and the functions of a master station, a substation and an execution station of the stability control system are achieved respectively. According to the invention, information interaction and function cooperation among a plurality of independent and dispersed subsystems in the original stability control system are realized, the diversity and function redundancy of the strategy of the stability control system are increased, and the operation reliability and expandability of a power grid are improved. And meanwhile, the cost and period of the stability control system in the new construction and transformation process are reduced, and good economical efficiency is achieved.

Description

Technical field: [0001] The invention belongs to the technical field of electric power systems, and in particular relates to a distributed intelligent safety and stability control system architecture method for a power grid in which a generalized safety and stability control system device is deployed and coordinated at multiple nodes in a power grid to realize all safety and stability control strategies in an area. . Background technique: [0002] With the rapid development of UHV AC and DC power grids and the large-scale development and investment of new energy sources, the operating characteristics of power grids have undergone profound changes. The safety and stability control system is the second line of defense to ensure the safety of the power grid. The regional stability control system involves a lot of equipment. The stability control devices of multiple plants and stations form a system, and the stability control strategy of large-scale power systems is relatively c...

Problems solved by technology

However, under this construction method, a single stability control system has a single function and poor configuration flexibility. When a strategy is changed, it often needs to be accompanied by a new or reconstructed system. The cost of expansion is high, and information between different stability control systems cannot be exchanged. Nodes and strategies Lack of synergy between

With the proportion of high-tech energy and power electronic equipment in the future power grid, the randomness of the power grid working conditions and the flexibility of the operation mode will increase significantly, and the above-mentioned traditional stability control framework can no longer be fully applied
