Wind turbine is a complex nonlinear system that the exact model of this system is not available, so it can be represented as an uncertain system. Thus, the control of this system is an important topic. Most of methods that design controllers for wind turbines consider these systems in suitable weather condition. While many turbines work in cold weather condition, in this paper, wind turbine is considered in cold weather, and in ice on turbine blades are considered as model uncertainties. A robust controller is designed for the wind turbine, in order to control the pitch angle. Performance of the proposed controller is evaluated in a comparison study.

“…The control strategies might be the same as shown in Figure 6 for a weaker converter and then the continuous over-current will be prevented. RSC can also be controlled as in the ideal state and the behavior of DFIG was analyzed in [8,22].…”

“…As described in Table 2, the second eigenfrequency mainly depends on the flexibility of the rotor and LSS with the invariant inertias while the higher eigenfrequencies are dominated by the gearbox. In practice, the coupling is a connection between the output shaft of the gearbox and generator and used for the misalignment of shafts, but it reduces the effective stiffness of HSS in the drive train model [8]. Figure 12 shows the relationship of the three eigenfrequencies with HSS stiffness and the vertical coordinate is logarithmic.…”

“…A comparison on the response of mechanical parts under single-phase and a three-phase voltage dip conditions was studied. In [8], the dynamic response of transmitted torque onto the gears in each stage due to the small voltage dip (90%) was analyzed and a detailed gearbox was built in Simscape [9]. Moreover, the transmitted loads through the high-speed shaft (HSS) with different stiffness to the gearbox were evaluated.…”

Impact of the Converter Control Strategies on the Drive Train of Wind Turbine during Voltage Dips

Abstract:The impact of converter control strategies on the drive train of wind turbines during voltage dips is investigated in this paper using a full electromechanical model. Aerodynamics and tower vibration are taken into consideration by means of a simulation program, named FAST. Detailed gearbox and electrical subsystems are represented in MATLAB. The dynamic response of electromagnetic torque and its impact on the mechanical variables are the concern in this paper and the response of electrical variables is less discussed. From the mechanical aspects, the effect of rising power recovery speed and unsymmetrical voltage dips are analyzed on the basis of the dynamic response of the high-speed shaft (HSS). A comparison of the impact on the drive train is made for two converter control strategies during small voltage dips. Through the analysis of torque, speed and tower vibration, the results indicate that both power recovery speed and the sudden torque sag have a significant impact on drive trains, and the effects depend on the different control strategies. Moreover, resonance might be excited on the drive train by an unbalanced voltage.
