Reconfiguration of the electrical network in a shipboard power system (SPS) is one of the most important methods to restore power supply and improve survivability of the SPS. In this paper, the problems involved in shipboard power system reconfiguration, such as network topology and network analysis, reconfiguration algorithm, reconfiguration mathematical model, multi-agent system based on design and so on, are all studied in detail.First of all, analyzing the characteristics of the shipboard power system, the paper is analyzed shipboard power system network topology, giving a unified model and attributes of power supply network and distribution network. Using a tree-search method, the paper makes a number of each generator, load, branch, node, formatting the shipboard power system network, according to network structure connected, a tree structure is generated.Second, based on analyzing reconfiguration algorithms, the paper gives improved Environment Priority Agent (EPA) algorithm, which is logically and physically decentralized multi-agent system oriented. The Environment Priority Agent algorithm is used to consideration to the whole navigation process is a sequence of operating conditions and study load priority order with different conditions and generator capacity in the network reconfiguration impaction, analysis and design of the agent function and structure in shipboard power system.Third, based on full consideration of the dynamically load priority with different condition, taking the operating condition of cruise and the war as an example, a variety of electric equipments based on connection structure, multi-agent system is designed into generator agent, motor agent, load agent, break agent and establish mathematical model, giving the generator capacity, formatting the network reconfiguration failure recovery framework.Finally, testing fault occurred in typical parts of the ship power system, such as motor, load, switch, generator and so on, design ship power system simulation platform. Simulation results illustrate its effectiveness of the Environment Priority Agent algorithm.
