【摘要】 电力通信网作为现代电网控制系统的重要基础设施,其网络可靠性直接关系着电力系统的正常生产运行。针对单纯的定性或定量分析均不能有效的完成对电力通信网的评估,本文在云理论的基础上,建立了综合能力模型以及可靠性评估云模型,提出了一种新的具有可操作性的电力通信网可靠性评估方法,解决了可靠性评估中定性语言到定量的转化问题,评估结果具有传统定性划分的直接可视性,符合人的思维习惯。论文最后给出实际的电力通信网的可靠性评估例子及优化方案。更多还原

【Abstract】 As the important infrastructure of modern power grids control system,power communication network(PCN) reliability is directly related to the reliability of the electric power system operation.Only qualitative analysis or quantitative analysis can’t effectively complete power communication network evaluation,based on the cloud theory,the model of system performance model and the cloud model of the reliability assessment are proposed.A new way for reliability assessment of power communication network is given and it can solve the transition problem between qualitative and quantitative in reliability assessment.The result of assessment can reflect mode of our thinking while keeping the direct visibility.Finally,this paper gives the reliability assessment of a power communication network using the formulae and Optimization.更多还原
