【 摘 要 】

A short-term reliability evaluation method based on time-varying dynamic fault tree is proposed for the time-varying and redundancy dynamic characteristics of the short term reliability of the microgrid operating in the main and Slave Island. First, a time varying dynamic fault tree is defined, and the solution process of dynamic subtree and static subtree is given. Then the top event is divided into direct and indirect events based on the power supply interruption of the load point, and the probability calculation is carried out. On this basis, the load probability and the expected power outage of the load point of the microgrid with master-slave control are calculated, and the reliability evaluation process is given. The validity and effectiveness of the proposed method are verified by an example analysis. The results can provide a basis for the operation and operation of the microgrid operating in the isolated island.
