ANFIS based Doubly Fed Induction Generator for WECS with LLCL-2TRP Filter
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 6
Abstract
The wind energy conversion system integrated with a doubly fed induction generator. The PWM based back-toback power converters produced harmonic and as well as the non-linear loads are also a contributor of harmonics. Filters are used to eliminate these harmonics. In this work,there is a proposal for the passive filter named LLCL-filter with two traps for mitigating the harmonics. The DFIG based WECS analyse the harmonics mitigation under the non-linear loads with LLCL filter. The traditional controllers for controlling the rotor side converters (RSC) for active power and MPPT are substitute with the adaptive neural fuzzy inference system (ANFIS). ANFIS basic structure and principle of working are presented in this paper. The Simulated result shows the performance of filter connected DFIG under the non-linear load with varying wind speed and also shows the improved response than conventional controller. The THD of signal carried out through FFT. Simulations in MATLAB/Simulink verify the responses of filter.
