常规的系统可靠性分析方法以变电站保护分析为主,出现了系统可靠性冗余分析的问题,影响分析精准度,因此提出了基于信息物理接口矩阵的变电站自动化系统可靠性分析方法.提取变电站自动化系统可靠性分析的冗余特征,分析功能冗余与网络冗余对系统可靠性分析的影响,避免系统可靠性冗余分析的问题.基于信息物理接口矩阵计算自动化系统的可靠度,生成系统信息层元件的空间状态,表示各个元件在正常工作与非正常工作的发生概率,从而分析各个元件的可靠性.采用仿真实验,验证了该可靠性分析方法的精准度更高,具有较高的推广价值.
Reliability Analysis Method for Substation Automation Using Information Physical Interface Matrix
Conventional reliability analysis methods mainly focus on substation protections,leading to the problem of reli-ability redundancy and inadequate accuracy.Therefore a reliability analysis method for substation automation systems based on information physical interface matrix was designed.The method avoids the problem of reliability redundancy by extracting redundancy characteristics from substation automation reliability and analyzing the impact of functional redun-dancy and network redundancy on reliability analysis.It realizes reliability analysis of all individual components by calcu-lating automation reliability degree using information physics interface matrix,generating spatial state of system informa-tion layer components,and characterizing normal/abnormal states probabilities of each component.The proposed reliabil-ity analysis method was proved to have higher accuracy and deserve popularized application.
