    Abstract:

    In order to overcome the problem that the traditional distribution network fault location method has poor adaptability to distributed power generation(DG) access, and the need to configure a large number of measuring devices in the feeder to cause cost increase, a fault location method for multi-source distribution network based on correlation coefficient of current sequence component is proposed.Firstly, the superposition method is used to analyze the current characteristics and positioning principle of the fault point of the multi-terminal power distribution network.Then, the power terminal measurement device is used to obtain the amplitude difference of the output current of the power supply before and after the fault, and then assume that the fault occurs at different positions and calculate the theoretical value of the fault current of each power supply output.Finally, the correlation analysis method is used to calculate the correlation coefficient between the theoretical and measured data, and extract the two adjacent nodes with the largest correlation coefficient to achieve segment location.The improved IEEE 33 node model simulation measurement value is built by ETAP power system simulation platform.The Matlab programming is used to analyze the correlation.The result verifies the correctness of method.
