Traditional power distribution systems in ship field usually adopt power breakers, contactors, relays and fuses as power distribution devices, thus result in low fault response and lack of current-limiting, so loads with high current spikes when started may result in large voltage drop on the DC power bus or misoperation of the power distribution branch, moreover, short-circuit may bring great damage to the whole power system. In this paper, a smart power distribution equipment is proposed, to automatically distinguish different load type and state, realize current-limiting when large capacitive load is started and cut off the power distribution branch whenever short-circuit occurs. This technique greatly increases the smart management capability of the power system. The feasibility and effectiveness of this technique is verified by the experiments carried out on a 24V/2kW prototype.

Network architecture is a protocol set of hierarchy architectures. Network performance with respect to its application should be improved as for its innovation and improvement under the condition of keeping up or extending its functions. Routing strategy research is important to carry out the above. In principle routing methods is concerned with the shortest routing, the lowest cost, the largest flux or the lowest extent of its congestion. We put forward a kind of routing strategy about intelligent selection basing on multi-agent system in order to overcoming the defect of routing selection strategies appeared at present as well as combining with the demand of high-performance.
