Embodiment Construction

[0028] The BDI multi-agent based ship power system fault reconstruction method multi-agent works in a decentralized way to enhance the reliability of the power system, and the application of each agent in the ship power system adopts a node structure. This method is to design and test the multi-agents of the ship power system on the JADE (Java Agent Development Framework) platform, and simulate the regional power distribution system of the control object ship under the environment of MATLAB\Simulink. Among them, the multi-agents simulated in JADE Information exchange between agents does not consider the time delay of communication.

[0029] (1) The first part (BDI multi-agent reconstruction realization)

[0030] The realization of the BDI multi-agent ship power system reconfiguration method is carried out by simulating the logical thinking and reasoning ability of human beings, and its internal state has three core data structures: belief, will and intention. Belief is the un...

Abstract

The invention relates to control in fault reconstruction of ship electric-power systems, and discloses a ship electric-power system reconstruction method based on BDI (belief-desire-intension theory) multi-agent, aiming to research on the reconstruction problem during three-phase short-circuit earth fault by taking a ship regional distribution system as a control target. The overall ship electric-power system agents include the type of decision agents and the type of execution agents; the BDI agents acquire information of electric quantity and switch state quantity by the aid of sensors to establish the belief reflecting running states of the ship electric-power system and generate the system reconstruction strategic desire during the fault and the executable intension which takes constraint of the electric-power system into consideration under effects of an associative memory unit and a chaotic neural network. The belief, the desire and the intension of the BDI agents are completed through support of a digital controller, an air circuit breaker, an automatic device breaking switch, a contactor and an actuator act on the ship electric-power system, and thus fault reconstruction of the electric-power system is realized, fault load is eliminated effectively and safety and reliability of the ship electric-power system are guaranteed.

Description

Technical field: [0001] The invention relates to fault reconfiguration control of a ship power system, in particular to a BDI (belief-will-intention) multi-agent based fault reconfiguration method for a ship power system. Background technique: [0002] With the rapid development of my country's shipbuilding industry and navigation, the capacity of the ship's power system continues to increase, and the requirements for the safety and reliability of the power system are getting higher and higher. In order to meet the high reliability requirements of the ship power system for power supply, the fault reconfiguration of the ship power system has been researched and applied as an additional optimization method for reconfiguration when a fault occurs. In recent years, as an important part of distributed artificial intelligence, multi-agent technology (Multi-Agent, MA) has developed rapidly in the application of power system reconfiguration, and BDI agent, as a typical cognitive typ...
