Fault Ranging Method for Medium Voltage Distribution Lines Based on SSA Optimization

To tackle the problem of accurate fault location in multi-branch distribution lines, a fault identification method is proposed on the foundation of optimized sparrow search algorithm. The method focuses on the optimal selection of variational modal decomposition parameters using the sparrow search algorithm, which solves the problem of deviation of distribution line fault ranging results due to the uncertainty of the variational modal decomposition parameters, and has higher localization accuracy and reliability compared with the traditional fault location algorithms.
