Self-adaptive intelligent coordination protection and control system for power grids based on WANs (Wide Area Network) and multiple agents

Abstract

A self-adaptive intelligent coordination protection and control system for power grids based on WANs (Wide Area Network) and multiple agents has the design scheme that according to the characters of hierarchical structure and geograhical distribution of a power system, a developing and modeling method of the software Agent is used to establish a divisional and hierarchical system. The system realizes coordination of protection actions by the capacity of a multi-agent system for solving distributed on-line questions. Through the plan to protect setting tasks, each agent is responsible for a specific task, and thus, the multi-agent system can establish knowledge libraries of all agents rightly and obtain high search efficiency. Each agent improves performance per se by exchanging information and learning from others, and then improves the capacity of the whole self-adaptive coordination protection system for solving questions. Because of the loose coupling relationship among the agents, the whole system has a more flexible structure and has real-time response to environmental changes.

Description

【Technical field】 [0001] The invention belongs to the technical field of power system self-adaptive protection, in particular to a research on intelligent self-adaptive coordinated protection based on wide area network and multi-Agent power grid. 【Background technique】 [0002] The essence of adaptive control is that the protection setting value should be automatically adjusted with the change of the power grid operation mode, so as to maintain its optimal performance, which can better solve the problems existing in the traditional protection system. The adaptive protection system needs to obtain real-time and accurate changes in the operation mode of the power grid, and timely correct the incompatible fixed values ​​to ensure the correctness, rapidity and selectivity of its actions. Agent is a self-governing, independent and social entity. It can decide its own intelligent behavior according to the changes of the surrounding environment and its own knowledge, and can reali...
