摘要
Abstract
In distribution network, the outage loss of important power consumers occupies the vast majority of the total outage losses. For this reason, the important power user-based load model, the system model and the outage loss cost model, by which the reliability of distribution network and its economy are analyzed, are built. Beginning with the designing of user questionnaires, the outage loss functions for big industrial consumers, whose production process is complex and their losses caused by interruption are huge, and consumers in other categories are determined, then the load models are built. Utilizing consequences analysis on failure modes, correct reliability indices of distribution network are chosen to compute the reliabilities of load points, thus the system model is built. According to outage loss evaluation rates of load points, the outage loss cost model is built. The reliabilities of load points and system reliability as well outage loss are estimated under three different connection modes, and the effectiveness and accuracy of above-mentioned models are verified by estimation results. It is pointed out that the adoption of distribution generation （DG） is an effective approach to reduce the outage loss in distribution network and improve social emergency capability.关键词
