The main contribution of this paper is to present a proposal for the development of an active power filter (APF) for a wind power generation system connected to the electric grid, using the three-phase induction generator with squirrel cage rotor (SCIG). In the induction generator side converter (IGSC) the power control is done by the magnetizing current and electromagnetic torque in coordinates dq. Thus, the wind system controls the active and reactive powers, as well as performing the active filtering function in the grid currents. Harmonic compensation is performed by an algorithm applied to the grid side converter (GSC). That technique improves the power quality and keeps the voltage at DC bus. The studied system was mathematically modeled and simulated using the Matlab / Simulink software. When SCIG provides 2 kW of active power, the THD from 18,94% (without APF) was reduced to 3,93% for GSC operating with APF function.

Active Power Control

To deal with the randomness and uncertainty of the wind power generation process, this paper proposes the use of the clustering method to complement the multi-model predictive control algorithm for active power control. Firstly, the fuzzy clustering algorithm is adopted to classify actual measured data; then, the forgetting factor recursive least square method is used to establish the multi-model of the system as the prediction model. Secondly, the model predictive controller is designed to use the measured wind speed as disturbance, the pitch angle as the control variable, and the active power as the output. Finally, the parameters and measured data of wind generators in operation in Western China are adopted for simulation and verification. Compared to the single model prediction control method, the adaptive multi-model predictive control method can yield a much higher prediction accuracy, which can significantly eliminate the instability in the process of wind power generation.

Adaptive hysteresis band current control(AHB CC) is used to control the three-phase grid currents by means of grid side converter in wind power generation system in this paper. AHB has reached the good purpose with PLL (Lock phase loop). First the mathematical models of each part are given. Then the control strategy of grid side converter-based wind power generation system is given in detail mainly including ABH CC and PI controllers of DC-link voltage, active power, reactive power. Finally the simulation model is set up which consists of power circuits, such as the grid side converter, LCL filter, transformer and grid, and control parts, etc. The simulation results have verified that the control strategy is feasible to fit for control of gird currents, active power, reactive power and DC-link voltage in wind power generation system.

Virtual flux oriented direct power control (VFDPC) is combined space vector modulation (SVM) with PI of DC-link voltage, active power and reactive power to control the grid side converter in wind power generation system in this paper. VFDPC has reached good performances with PLL (phase lock loop). First the mathematical models of grid side converter, LCL filter and phase lock loop are given. Then the control strategy of grid side converter-based wind power generation system is given in detail. Finally the simulation model is modeled consisting of power circuits, such as the grid side converter, LCL filter, transformer grid, and control parts, such as PI controllers of DC-link voltage, active power, reactive power, and SVM, and so on. The simulation results have verified that the control strategy is feasible to fit for control of gird currents, active power, reactive power and DC-link voltage in wind power generation system.
