Multi-agent grid fault diagnosis system and method based on blackboard model

Abstract

The invention provides a multi-agent grid fault diagnosis system and method based on a blackboard model. A task planning Agent of the system divides a multi-agent system; a first information acquisition Agent acquires relay protection information of a power grid in real time, a second information acquisition Agent acquires circuit breaker information of the power grid in real time, and the information is transmitted to a blackboard model sharing platform; the blackboard model sharing platform determines whether the transmission data of the relay protection information and the circuit breaker information are fault data by setting a switching function, updates the received fault data, and obtains the accurate fault data; an information transmission Agent compares and superimposes the received accurate fault data one by one, and obtains the final fault data; a topology Agent determines the topological structure of a fault region; and a fault diagnostic Agent conducts a fault diagnosis to diagnose faulty elements using a Petri network based on the fault data and the topological structure of the fault region.

Description

Technical field [0001] The invention belongs to the field of electrical engineering, and specifically relates to a multi-agent power grid fault diagnosis system and method based on a blackboard model. Background technique [0002] Electricity, as the backbone resource related to the country's economic development, has gone through many years of development in my country and has gradually integrated with the world and is in a leading position in development. The intelligent development of power grids has become a mainstream trend. But no matter how the power grid progresses and develops, fault diagnosis is inseparable. When the power grid fails, various fault diagnosis techniques become an important means to save economic losses. The subject research of fault diagnosis and fault recovery has an immeasurable effect on the development of power system. At this time, continuous improvement of fault diagnosis technology is required, including accuracy and fault tolerance. [0003] As...
