Abstract |
Recent development in the wind energy technology, wind energy generation has been emerged as the fastest growing technology and most clean energy source to produce electrical power in Pakistan as well as across the world. Several topologies (i.e. induction machine, double fed induction machine and synchronous machine) with different configurations based on advanced power electronic converters are commercially available for modern wind turbines. Among different wind turbine topologies, permanent magnet synchronous generator (PMSG) with full scale converter (FSC) based wind turbine is preferred due to its advantages of maximum power extraction, variable wind speed operation and to support grid even during disturbance (i.e. fault condition) but it generates harmonic problems due to nonlinear characteristics of its converter and non linear loads connected from grid side. The other challenging task in grid connected wind farms is fault detection. Hence in this work, the total harmonic distortion analysis of wind farm (using synchronous generator full scale converter based) integrated with grid is carried out using Fast Fourier Transform (FFT) analysis to evaluate the Total Harmonic Distortion (THD) of output current at different fault conditions with help of MATLAB / SIMULINK software, also to classify faults and analyze harmonics to maintain continuity and quality of power. |
