Abstract

For the operating characteristics of limited capacity micro-grid, power quality disturbance impacting on the micro-grid is to be significantly larger than the civilian power grid, especially the transient power quality disturbances can not be ignored. By combining the advantage of wavelet transform and FFT (Fast Fourier Transform) respectively in the steady-state and transient power quality detection, a new method of power quality detection on limited capacity micro-grid is proposed. Firstly, limited capacity micro-grid model is established by MATLAB, then, the common micro-power system disturbance models are generated, finally, wavelet transform and FFT are combined to complete the detection and analysis of harmonic, and the detection and location of transient power quality disturbances. The simulation results show the effectiveness of the method which provides a new research idea for detection and location of power quality in limited capacity micro-grid.
