Ship electric system failure recovery method based on multi-agent technology

Abstract

The invention provides a ship electric system failure recovery method based on a multi-agent technology. A ship comprehensive electric system failure recovery algorithm is designed through a figure track analysis and multi-agent technology. A figure track analysis method is used for establishing a ship comprehensive electric system figure model, each side in the figure model corresponds to a component in a physical electric system, each main component has an agent of the main component, and component tracks are used for managing an electric system figure model topological structure and traversing other component agents. On the basis, the method uses the functions of information exchanging, interaction effect, cooperation, coordination work and communication of the agents as a foundation, and a ship electric system failure recovery task is completed in a coordination mode. The method can process the multi-priority failure recovery problem of an electric system with a loop and a load of the electric system, and under the premise that power supply recovery is carried out on a high-priority component preferentially, power supply recovery is carried out on outage components as many as possible.

Description

technical field [0001] The invention relates to the field of marine electric power technology, in particular to a fault recovery method for a marine electric power system based on multi-agent technology. Background technique [0002] The environment of the ship is harsh, and its electrical components are susceptible to various failures or abnormal operating states due to the harsh environmental conditions, thereby affecting the normal power supply of the power system. Once many important power-consuming components lose power, it will seriously affect the safety of the ship. Therefore, , it is urgent to solve the problem of fast restoration of power supply for power-off loads after power component failure, so as to improve the reliability and continuity of system power supply. [0003] The basic requirement for ship power system fault recovery is to change the network topology by adjusting the combined state of the segment switch and tie switch in the network under the constr...

Problems solved by technology

[0004] There are certain problems in the current ship power system fault recovery schemes. For example, some design schemes limit the priority number of grid loads, and can only divide the priority of ship loads into important loads, secondary important loads and non-important loads. level, and prohibit changing the priority of the load, so that the optimality of fault recovery cannot be guaranteed; there are many methods that need to use matrix or linear programming to determine the fault recovery plan, which reduces the rapidity of response to system chan
