A Novel Approach for Reactive Power Copensation in Wind Farms using GSC and RSC Control Alogrithms

In this paper, we proposed a working and operation of Doubly fed induction generator (DFIG) based wind energy conversion systems. Here the energy conversion system is having capabilities of integration of active power with grid-side converter (GSC). Here the objective of rotor side converter is to attain maximum power withdrawal that is required to supply reactive power to Doubly fed induction motor. In the paper a good control of Grid side converter is obtained, in addition to its slip power transfer, harmonics has to be supplied. A static compensator is used for mitigating those harmonics in case of the wind turbine is in shutdown situation. Here we are using Matlab and simulink software for simulating the proposed Doubly fed induction generator (DFIG) based wind energy conversion systems using both GSC and RSC (Rotor Side Converter) control algorithms and check its performance. These simulation results are validated with developed DFIG system for various practical conditions, such as variable wind speed and unbalanced loads or single-phase loads.
