舰船环形区域配电结构及可靠性分析

舰船电网形式的选择直接关系到电力系统供电的可靠性，其重要性不亚于电站。在对舰船电网形式进行分析研究的基础上，利用基于可靠性框图的网络分析法，对几种典型的船舶电网进行了可靠性计算。通过分析对比四种船舶电网，得到环形区域双向供电方式的可靠性水平高于辐射网结构和电源环形网结构，是船舶电网结构发展的方向。

On distribution structure and reliability of shipboard loop area

The configuaration of shipboard power network directly affects the reliability of power supply,and is not less important than power station itself.The configuarations of shipboard power network have been analyzed at first.Then network analysis method based on reliability diagram is adopted to analyze four classical configuarations of shipboard power network.Results confirm that the loop zone distribution has higher reliability than radiation network and loop power network.Therefore,the loop zone distribution structure can be the direction for the development of shipboard power network structure.
