Analysis of Ring Distribution Grid Reliability Based on Dynamic Fault Tree and Bayesian Network

The fault tree analysis (FTA) approach is a constructive technology, used broadly and generally for analyzing the reliability of power system. FTA is applicable for evaluating the intricate operation such as power distribution system. Bayesian network is a graphical probability model. Graph depictions of Bayesian network lead to models for explanation, make mathematical algorithms easier as well as have efficient inferences. When combining two approaches to determine the reliability of circular-shaped distribution grid having back-up system, reserved components will produce reliable results. This work presents the application of FTA and Bayesian to examine the reliability of ring distribution grid, using IEEE RBTS Bus2 diagram for calculation and comparison
