Fault detection algorithm for grid based on dynamic grey prediction
基于动态灰色预测的网格故障检测算法

In order to satisfy the requirement of the fault detection of grids, a dynamic-grey-prediction-based fault detection algorithm was presented. According to the unreliable failure detection theory, models for grid systems and fault detection were established respectively. Combining heartbeat strategy with grey prediction method, a dynamic heartbeat strategy was designed, and the prediction model was presented, as well as a real-time prediction strategy. Furthermore, on the basis of the dynamic heartbeat strategy, a fault detection algorithm for grid environments was brought out, and its dependability was analyzed. At last, simulation results prove the validity and correctness of the algorithm.
