“…However, the performance of conventional DPC deteriorates due to the variable switching frequency. Moreover, the generated stator power can be controlled based on a portion of the turbine power by employing the feedback variable in the DPC controller [23]; the change in the turbine speed depends on the difference between turbine power and total generated power. Hence, this method can be degraded for controlling the generator speed and complicating the AC filter design.…”

Abstract:A feasible control strategy is proposed to control a doubly fed induction generator based on the wind energy converter system (DFIG-WECS). The main aim is to enhance the steady state and dynamic performance under the condition of the parameter perturbations and external disturbances and to satisfy the stator power response of the system. Within the proposed control method, the control scheme for the rotor side converter (RSC) is developed on the model predictive control. Firstly, the self-adaptive reference trajectory is established from the deduced discrete state-space equation of the generator. Then, the rotor voltage is calculated by minimizing the global performance index under the current prediction steps at the sampling instant. Through the control scheme for the grid side converter (GSC) and wind turbine, we have re-applied the conventional control. The effectiveness of the proposed control strategy is verified via time domain simulation of a 150 kW-575 V DFIG-WECS using Matlab/Simulink. The simulation result shows that the control of the DFIG with the proposed control method can enhance the steady and dynamic response capability better than the conventional ones when the system faces errors due to the parameter perturbations, external disturbances and the rotor speed.

The use of wind energy is increasing due to rapid increase in energy consumption and rapid deployment of wind energy. Among different types of wind turbine generators, doubly fed induction generators are most widely used because of their low cost and capability to work in different wind speeds. On the other hand, doubly fed induction generators (DFIGs) are very sensitive to voltage drop. If a fault occurs in the network the voltage of DFIG terminal drops. So the rotor current increases and this may lead to damage DFIG converters. So, a protection system must be used to protect DFIG converters. One of the common schemes used to protect DFIGs is crowbar protection. In this paper, the effects of static volt ampere reactive compensator (SVC) on DFIG operation during voltage drop and crowbar protection are investigated in detail. Results show that by using SVC the voltage drop of DFIG terminal during grid faults decreases. Therefore, the operation time of crowbar decreases and the fault ride through capability of DFIG increases.

“…Thus, to ensure maximum efficiency of electricity generation, it is necessary to be able to adjust the rotation speed of the generator shaft. For this purpose, asynchronous generators made according to the scheme of the doubly-fed induction generator (DFIG) [4,5] are used. The angular frequency of generator rotation, depending on the design, is determined by the difference or the sum of the voltage frequencies supplied to the stator and rotor windings.…”

The article is devoted to the improvement of control systems for wind turbines by developing fuzzy controllers with higher transient characteristics and low computational costs of identification in comparison with the applied PI controllers. Based on the self-organization method, a fuzzy speed controller of the doubly-fed induction generator (DFIG) of a wind turbine was synthesized, which uses a zero-order Sugeno fuzzy inference system and is made in the form of a block-oriented Wiener model. This regulator is an element of the vector control system of the transistor converter on the rotor side. The results of simulation modeling of the fuzzy controller showed that it provides a lower transition time compared to the PI controller, by 53.59% during acceleration and by 79.76% during braking, and 23.81% less error speed deviations from the reference signal. Such indicators can minimize losses while maintaining the maximum output power point of the power plant. The implementation of the developed system on wind turbines contributes to increasing the efficiency of wind farms, reducing the cost of electricity production, reducing the payback period of equipment, and the sustainable development of alternative energy in general.
