To deal with a variety of operation modes of distribution network and ensure the selectivity and sensibility of feeder protection, the recording device is introduced to the feeder and installed at proper position to record operation status of feeders in various operation mode. First, the recording files will be analyzed after being uploaded to protection setting & recording data management system. Second, the fault position will be identified with the help of network topology analysis. Third, according to installation of recording device and recording time sequence, the recording data weight is calculated. Last, the protection setting will be revised by multiple regression algorithm. The protection settings will be linked to recording characteristic data and feeder operation modes to join into feeder recording character map, which is a helpful investigation of the optimization of distribution network setting management work.
