The sliding mode pitch angle controller design for squirrel-cage induction generator wind power generation system

Abstract

The new pitch angle controller is designed for squirrel-cage induction generator (SCIG) wind power generation system by using sliding mode control method. Firstly, wind turbine generation (WTG) model is established by using the state variables of angular speed of windmill rotor, wind speed, pitch angle and so on. Secondly, the sliding mode pitch angle controller is designed making use of the constant reaching law which keep the output power of WTG at the rated power. Then, the proposed method is compared with traditional PID pitch angle controller via matlab software. The simulation results show that the system has more rapid and robust response and little deviations.

Advanced Type-2 fuzzy logic–based pitch-angle control strategy for wind energy system

“…The pitch-angle controllers are generally used to limit the aerodynamic power to its rated value when the wind speed exceeds the rated WT speed. In some previous works (Al-Saffar and Musilek, 2016;Garasi et al, 2014;Kadri and Khan, 2012;Konara and Kolhe, 2015;Mi et al, 2014aMi et al, , 2014bPoultangari et al, 2012;Sakamoto et al, 2006;Vega et al, 2015), different methods have been proposed to design the pitch control system to regulate the output power at rated level and improve the output power quality with frequent wind speed changes. Beside this, pitch-angle controller is also employed to stabilize the WES using pitch-angle controller for transient faults (Duong et al, 2015).…”

“…In this trend, some of the authors have designed rotor speed control-based pitch-angle controller to enhance the transient stability (Anderson and Bose, 1983;Muyeen et al, 2006;Shima et al, 2008;Tamura, 2001;Wasynczuk et al, 1981). In the previous literature (Al-Saffar and Musilek, 2016;Garasi et al, 2014;Kadri and Khan, 2012;Konara and Kolhe, 2015;Mi et al, 2014aMi et al, , 2014bPoultangari et al, 2012;Sakamoto et al, 2006;Vega et al, 2015), the pitch-angle controller for above rated wind speed was designed, where it regulates the generator output power to its rated value, and Wasynczuk et al (1981), Anderson and Bose (1983), Tamura (2001), Muyeen et al (2006), and Shima et al (2008) investigated the pitch-angle controller for transient stability enhancement. None of them (Al-Saffar and Musilek, 2016;Anderson and Bose, 1983;Garasi et al, 2014;Kadri and Khan, 2012;Konara and Kolhe, 2015;Mi et al, 2014aMi et al, , 2014bMuyeen et al, 2006;Poultangari et al, 2012;Sakamoto et al, 2006;Shima et al, 2008;Tamura, 2001;Vega et al, 2015;Wasynczuk et al, 1981) investigated the pitch-angle controller for both purpose (to maintain the power output to its rated value for above rated wind speed and transient stability investigation during network faults).…”

Performance improvement of a wind energy system using fuzzy logic based pitch angle control

“…This controller helps to maintain the aerodynamic power at rated value when the wind speed exceeds the rated wind speed. In some reported works [4][5][6][7][8][9], different methods have been proposed to design the pitch angle controller for regulating the active power at rated value and improve the power quality with frequent wind speed changes. Beside this, pitch angle controller is also employed to stabilize the WES under transient disturbances or faults.…”

“…Thus, the pitch angle control serves two purposes: In [4][5][6][7][8][9], they are used to regulate the generator output power at rated value for varying wind speeds while in [10][11][12][13], they are used for stabilizing the WES under transient disturbances or post fault operation. A study of the performance of the pitch controller in both these conditions is the subject of this paper.…”
