Control Strategies for Variable-speed Fixed-pitch Wind Turbines
This chapter deals with a design of controllers for variable-speed fixed-pitch wind turbines. The chapter begins with an introduction to wind turbine control and the detail of nonlinear models of the wind energy conversion system (WECS). Linearization around a set of equilibrium points is presented to obtain a linear parameter variable model from a nonlinear system. Open-loop characteristics fo...
متن کاملA novel control system design to improve LVRT capability of fixed speed wind turbines using STATCOM in presence of voltage fault
The design and implementation of a new control system for reactive power compensation and mechanical torque, voltage regulation and transient stability enhancement for wind turbines equipped with fixed-speed induction generators (IGs) in power systems is presented in this study. The designed optimal linear quadratic regulator (LQR) controller provides an acceptable post fault performance for bo...
متن کاملType-2 fuzzy logic based pitch angle controller for fixed speed wind energy system
In this paper, an interval Type-2 fuzzy logic based pitch angle controller is proposed for fixed speed wind energy system (WES) to maintain the aerodynamic power at its rated value. The pitch angle reference is generated by the proposed controller which can compensate the non-linear characteristics of the pitch angle to the wind speed. The presence of third dimension in the Type-2 fuzzy logic c...
متن کاملDesigning a fuzzy PI^lambda controller to control the pitch angle in wind turbines under variant speed
One of the main tasks of the control systems in the wind turbines is to maintain the power of the wind when its wind speed proceed its nominal value. Because the failure to maintain the power in its nominal value in the region of the turbine curve damages the turbine and increases the mechanical stress. This object is obtained by controlling the pitch angle in the third region of the turbine cu...
متن کاملPitch Angle Control for Variable Speed Wind Turbines Using Genetic Algorithm Controller
The pitch angle control is the most common means for adjusting the aerodynamic torque of the wind turbine when we rate wind speed, controlling various variables could be chosen, as generator power, generator speed and wind. As conventional pitch control customarily use PI controller, the mathematical model of the system should be well known. The controller design by the genetic algorithm is dev...
