舰船电力网络薄弱环节辨识方法研究

系统薄弱环节的辨识是系统可靠性分析中的一个重要因素。利用这些信息可以反映出可靠性与系统元件的相关性,从而发现系统可靠性的薄弱部分,为系统规划和运行提供理论依据。本文基于最小割集理论,利用可靠性追踪原理提出了一种适用于环形舰船配电系统的可靠性评估方法。通过计算该环形舰船电网各元件对系统不可靠度的分摊,辨识出对系统可靠性影响较大的薄弱环节。

Research on recognizing weak parts of shipboard power grid

Weak part analysis of a system is a key element in a system reliability quantification process. It enables the weakest areas of a system to be recognized and assists in directing remedial measures for improving the system reliability. This paper proposes an unreliability tracing technique for a ring shipboard distribution system. The case studies indicate that the developed technique can distribute the system unreliability indices to components reasonably, and can therefore be used to recognize the weak parts of a shipboard power system.
