摘要

A fast adaptive back-stepping terminal sliding mode power control strategy for both the rotor-side converter and the grid-side converter of doubly fed induction generator (DFIG) is proposed in this study. The proposed control strategy for the DFIG converters utilises the active and reactive power components derived from the three-phase voltage and current without the use of phase-locked loops. For a multimachine power network, incorporating long-distance transmission lines, inter area oscillation has been a critical issue. Additionally the integration of wind farm to the existing power systems results in the variation of its operating point over time due to unpredictable wind speed variation and consequent fluctuation in the power outputs. Further the proposed control strategy for the DFIG-based wind farms has been tested on a two- area four-generator system in MATLAB/Editor and MATLAB/Simulink environment subjected to different levels of wind power penetration. The significance and effectiveness of the proposed control strategy to damp out inter area oscillations have been illustrated in the simulation and result section.
