Probabilistic information about random variables describing equipment's reliability is not complete when there is a lack of statistical data about failure. The traditional reliability assessment cannot deal with the incomplete probabilistic information. Interval probability is an efficient method to address the incomplete probabilistic information. The interval value of reliability indices can reflect...
Distributed generation (DG) has developed rapidly in recent years, and its accession to electric distribution network has had significant impact on the power supply capability (PSC) of the network. Current studies on PSC have been based on deterministic security rules such as N-1 criterion while ignoring uncertain factors existing in the electric distribution network, and as a result, failing to quantitatively...
It's important for us to carry on reliability research of protection system. There are three methods to analyze and compute reliability index of electric relay protection system: Markov method, Fault Tree Analysis (FTA), Event Tree Analysis (ETA). The paper describes how to use these three methods to carry out quantitative analysis of protection system reliability and discusses feature and difference...
The electric generating unit's operational state of both history and scheme should be taken into consideration in the operational reliability evaluation of generating system. The generating unit's ageing failure is taken into account in the paper. The repairable failure unavailability and the ageing failure unavailability are deduced from the unified definition of unavailability, and the forced outage...
Taking the retailerpsilas default in supply chain for example, in this paper, using the theory of credit default swap, the writer intends to make a research on the shift of default risk in supply chain. On the condition of insured interest rate and recovery rate, a supposition is made that the default rate of supply chain depends on the doubly stochastic Poisson default process, and then a model of...
