复杂系统脆性树及其在船舶电网中的应用

Complex System Brittle Tree and Its Application to Shipboard Power System

基于脆性关系图获得引起复杂系统崩溃的脆性源子系统,并以此构造相应的脆性树,进而根据该脆性树中各子系统之间的传播概率以及根子系统受外界干扰而崩溃的概率得出各脆性源子系统的脆性度,据此对各脆性源进行等级区分,以利于对复杂系统进行有效的控制。最后以船舶电网为例,分析IEEE-RTS 79可靠性测试系统,得出引发船舶电网崩溃的各脆性源子系统。

Based on the brittle relation graph, the brittle sources subsystems induce the complex system to collapse are obtained and they are used to construct the brittle trees. According to the diffuse probability of each subsystem and the collapse probability of the .source subsystems, brittle degree of each brittle source subsystems is gained, and the brittle sources are differentiated as different grades to control the complex system conveniently and effectively. Finally, the IEEE-RTS 79 reliability testing system is taken as example, and the brittle sources which may lead the shipboard power system to collapse are obtained.
