舰船交流区域配电网络结构研究

Study on AC zonal warship electric power distribution networks

舰船配电网络结构是关系舰船电力系统可靠性的关键因素之一,现有的舰船配电网络结构已不能满足舰船电力系统发展的要求。本文介绍了舰船配电网络结构的技术发展水平,指出了现有配电网络结构中存在的不足。通过分析、研究现有的舰船配电网络结构和相关文献,提出了一种新型的舰船交流配电网络结构。介绍了配电网络结构可靠性指标,并将提出的配电网络结构与不同的舰船交流配电网络结构进行了负荷点故障率和系统可靠性指标比较。结果表明,所提出的配电网络结构具有较高的可靠性,是未来舰船电力系统的发展方向。

The network structure of warship electric power distribution is one of the key factors affecting the relibility of warship electric power system. The existing warship electric power distribution networks can not satisfy the power system＇s development. The state-of-the-art about warship electric power distribution network is introduced, and the deficiencies of existing distribution networks are point out. The existing warship electric power distribution networks and related papers have been analysed and researched, then a new distribution network is proposed. The reliability indices are introduced,and failure rates of load points and system indices of several different distribution networks are brought into comparison. The result shows that the reliability level of the new distribution network is better than others. The network will be the basical distribution network of future warship power systems.
