摘要
为实现对结构较为复杂的数字化变电站系统进行全面、细致的可靠性评估,首先构建了基于并行冗余协议的数字化变电站整体结构模型。然后将一种新的可靠性评估方法———成功流法,引入数字化变电站的可靠性分析中,以数字化变电站结构模型为基础,建立用于可靠性评估的成功流模型,并根据该模型进行推导,得出变电站的全局可靠性参数。最后利用灵敏度分析方法,分析了不同元件的可靠性变化对整个系统成功概率的影响。
In order to realize comprehensive and meticulous reliability assessment of digital substation system with complex structure,firstly,the overall structural model of digital substation based on parallel redundancy protocol is constructed.Then a new reliability assessment method which is called goal oriented methodology is introduced to the field of reliability analysis of digital substation.The goal oriented model used for reliability assessment is established based on the structural model of digital substation,and the overall reliability parameters of the substation could be obtained by deducing the model.Finally,the influence of system success probability caused by the reliability variation of different components is analyzed with sensitivity analysis method.
