Abstract

This paper presents active and reactive power control of a doubly-fed induction generator (DFIG) based Wind Energy Conversion System (WECS) by designing a sliding mode controller (SMC). The proposed SMC controller is developed to control the rotor side converter (RSC). It is implemented on a field-programmable gate array (FPGA)-based 1Hp hardware setup of WECS in the laboratory. Both the operating modes (sub and super-synchronous operating mode) are discussed in this paper. The experimental results shows the voltage and the current of stator, rotor and the grid. It also provide the performance of stator power, grid power with the variable speed operation of the rotor. With the use proposed SMC in the RSC of WECS provide good response on active and reactive power control.
