Abstract :
The premise of effective use of clean energy is to correctly determine malfunction zone of distribution network with distributed generation. Based on the matrix algorithm in the location of feeder terminal unit (FTU) to the malfunction of distribution network, a new adaptive matrix algorithm for the fault location in distribution network is proposed. According to flowed over-current through the FTU and its direction, firstly the algorithm judges whether distributed power put into operation, and whether the default happens. Then it preliminarily locates the malfunction zone in the distribution network. Secondly, on the basis of malfunction zone structure and over-current information of FTU, the fault matrix is formed adaptive, we could confirm of the fault zone. Lastly, comparing the detected fault current amplitude at both ends of fault circuit to form fault criterion, it could effectively exclude effects of incomplete and fault distortion information. The PSCAD/EMTDC simulation model and numerical example verifies accuracy and efficiency of the algorithm, and good mechanism of fault tolerance.
