摘要

With the recent initiatives to modernize large ship power systems, ship builders are integrating technologies with the aim of an all-electric energy system. Network reconfiguration is a main technology; the main objective in reconfiguration is to restore as many loads as possible without violating operating constraints. Condition of network reconfiguration is power flow .It often require hundreds even thousands times of power flow calculation. So the development of rapid and robust power flow algorithm for network reconfiguration is very important. The distinctive characteristics of shipboard networks are detailed first. Methods used to ship distribution networks such as forward-backward method, bus-impedance method, bus-voltage method are commented. As network configure are often altered with reconfiguration, power flow methods should be robust to change of network configure, so that it spend less time to compute. To three methods, comparative test is conducted on a new test system of a ship's distribution network. The performance of the power-flow methods is divided into speed of convergence, accuracy of the solution and robust ability. A comparative discussion of the test results is provided. By analysis of overhand methods, a power flow method is identified which is more suitable to network reconfiguration of ship power system.
