Testing Platform for Fault Diagnosis and Location Algorithm in the Active Distribution Network

Abstract

To test fault diagnosis algorithms in the active distribution network, this paper proposes a simulation testing platform based on phasor measurement units (PMUs). The platform is built in the MATLAB/Simulink software, which implements an open data source in COMTRADE format. The PMU model suitable for power distribution grid is constructed via different algorithms, which provides the voltage/current phasors of the recording waveform. The platform offers both Stateflow and MATLAB Function for diagnosis algorithm development to reduce the time of modeling. The efficiency of the platform is improved by using S-function and C-code generation. We convert the fault diagnosis algorithms module into a dynamic-link library (DLL) to enhance the portability of the algorithm. The platform provides an efficient way to test and verify new algorithms for fault diagnosis and location in the distribution power grid.
