Considering the normal operation possibility of the equipment and severity after fault in the process of equipment sensitivity evaluation, this paper focuses on the uncertainty happening in the actual event, and chooses entropy as the measure and then creates maximum hybrid entropy evaluation model. Based on this model, it can obtain the probability distribution and the membership with least subjective...
The assessment of equipment trip probability due to voltage sag is a complicated matter because of the uncertainties both from voltage sag in power systems and sensitive equipment in customer side. The uncertainties of influencing factors are difficult to determine especially the stochastic distribution of voltage tolerance of equipment. The characteristics of voltage sag are determined by sag severity...
