Book excerpt: This research focuses on the stand-alone operation of doubly fed induction generator (DFIG) with variable stator frequency. In stand-alone configuration, the stator side is connected to a three phase diode rectifier and a stand-alone electrical load. The dc output voltage regulation is achieved by applying stator flux oriented control scheme in synchronous reference frame. The losses that occur in the power electronics components depend on the current flowing through the switches and so in the power rating of the converter. WECS based on DFIG are designed for variable speed operation. So, the main objective of the DFIG control strategy is to regulate the generator speed so that maximum amount of wind energy is extracted for the given speed of the wind. But the generator cannot be run in full speed range if the converter rating used is smaller than the rated power of the turbine. Thus, the speed range of the DFIG is determined by the converter rating and hence the slip is limited using variable frequency operation of DFIG to reduce the converter rating and extend the speed range of operation. The dc-link capacitor voltage is regulated to a constant rated value and so the stator voltage amplitude is also constant. The flux-frequency product being constant, a variation in stator flux magnitude results in a frequency variation. So, the stator frequency can be scheduled in such a way that the output power is maximized. Some simulation tests have been run during this work to find the optimal stator frequency for a fixed range of speed and used as a look up table to improve the power conversion efficiency of the whole generator system.

Book excerpt: Master's Thesis from the year 2013 in the subject Engineering - Power Engineering, grade: none, , course: Electrical engineering (Renewable energy), language: English, abstract: Wind electrical power systems are recently getting lot of attention, because they are cost competitive, environmental clean and safe renewable power source, as compared with fossil fuel and nuclear power generation. A special type of induction generator, called a doubly fed induction generator (DFIG), is used extensively for high-power wind applications. They are used more and more in wind turbine applications due to ease controllability, high energy efficiency and improved power quality. This thesis aims to develop a method of a field orientation scheme for control both the active and reactive powers of a DFIG driven by a wind turbine.The proposed control system consists of a wind turbine that drives a DFIG connected to the utility grid through AC-DC-AC link. The main control objective is to regulate the dc link voltage for operation at maximum available wind power.This is achieved by controlling the and axes components of voltages and currents for both rotor side and line side converters using PI controllers. The complete dynamic model of the proposed system is described in detail. Computer simulations have been carried out in order to validate the effectiveness of the proposed system during the variation of wind speed. The results prove that , better overall performances are achieved, quick recover from wind speed disturbances in addition to good tracking ability. Generally, any abnormalities associated with grid asymmetrical faults are going to affect the system performance considerably. During grid faults, unbalanced currents cause negative effects like overheating problems and mechanical stress due to high torque pulsations that can damage the rotor shaft, gearbox or blade assembly. Therefore, the dynamic model of the DFIG, driven by a wind turbine during grid faults has been analyzed and developed using the method of symmetrical components. The dynamic performance of the DFIG during unbalanced grid conditions is analyzed and described in detail using digital simulations. A novel fault ride-through (FRT) capability is proposed (i.e. the ability of the power system to remain connected to the grid during faults) with suitable control strategy in this thesis. In this scheme, the input mechanical energy of the wind turbine during grid faults is stored and utilized at the moment of fault clearance, instead of being dissipated in the resistors of the crowbar circuit as in the existing FRT schemes.

This book was released on 2010 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis studies the basic concept of doubly-fed induction generators (DFIG) and develops a laboratory model to simulate DFIG wind turbine generators (WTG). 0́−Doubly-fed0́+ refers to the three-phase stator and rotor windings, both of which have electric power exchange with the ac power system. Different from synchronous generators installed in coal, oil, gas, hydro, and nuclear power plants, asynchronous DFIG generators are widely used for wind energy conversion because of the diversity of wind power. Through the control of back-to-back PWM converters connected between the DFIG rotor and power system, a DFIG can operate at variable speed but constant stator frequency. Below rated wind speed, the DFIG controls the torque on the turbine shaft to track the best operating point (i.e. at best tip-speed ratio). Above rated wind speed, the pitch angle of the turbine blades is adjusted to limit the power captured from the wind. DFIG can provide power factor regulation by controlling the reactive power exchange with the grid. In this laboratory DFIG experiment, a DC motor is open-loop controlled as a prime mover with variable mechanical power output. A wound-rotor induction motor is mechanically coupled to the DC motor and operated as a DFIG. An IGBT inverter is connected to a variable DC voltage source in order to provide a controllable three-phase voltage applied to the rotor windings. The reactive power output is controlled by setting the magnitude of the rotor excitation voltage. The active power (torque), reactive power output and speed can be controlled by setting the frequency of the rotor excitation voltage. Through manually adjusting the DC input and rotor excitation voltage, the laboratory DFIG is able to operate at a variable simulated wind speed (4 0́3 25 m/s) with desired power output following the GE 1.5 MW WTG. As an advanced control strategy, decoupled d-q vector control for DFIG using back-to-back converters is studied. Under a stator-flux oriented reference frame, for the rotor-side converter, the rotor d- component (i.e. vrd, ird) controls the stator reactive power (rotor excitation current), while the rotor q- component (i.e. vrq, irq) controls the stator active power (electrical torque); for the supply-side converter, the d- component (i.e. vd, id) controls the DC-link voltage, while the q- component (i.e. vq, iq) controls the reactive power.

This book was released on 2009 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work presented in this thesis includes control system design, analysis and grid synchronization of a DFIG (doubly-fed induction generator) driven by a wind turbine using stator-voltage and stator-flux oriented frames. The DFIG is a special type of induction machine which is comprised of two back-to-back converters. One converter connects the DFIG stator to the grid, and the second converter is connected to the rotor of the machine through a DC-link capacitor. In this work, DFIG steady-state and transient models have been created in the d-q reference frame. The steady-state model is used to obtain the relationship between the rotor d-q currents and stator real/reactive power references in a particular orientation frame. The transient model is used to develop the DFIG power control mechanisms. The wind turbine driving torque is modeled by considering typical wind turbine aerodynamic characteristics under variable wind and pitch angle conditions. Comparisons are made to evaluate the differences between DFIG current/power controller in stator-voltage and stator-flux oriented frames. A speed control system has been designed to analyze maximum energy extraction from a DFIG for a particular wind speed. Lastly, the grid synchronization control technique and synchronization method have been proposed as this system requires some care during the machine start-up and integration with the grid. The main aim of the synchronization control process is to avoid heavy start-up currents and mechanical stresses on the turbine shaft and other integrated components. This is achieved by properly matching the phase angle, frequency, and magnitude of the grid voltage and the stator induced voltage irrespective of whether it is a stator-voltage or stator-flux oriented frame used for modeling the generator. Instead of a traditional control scheme using a PLL (phase-locked loop), the rotor d-q reference current is generated with grid voltage as the reference so as to induce identical voltage in the stator as that of the grid. The machine is started by a driving torque and the switch between stator and the grid can be closed for synchronization. However, appropriate timing of switch closure plays a critical role in satisfying the magnitude condition of synchronization. Simulation models have been developed using Matlab®/Simulink® for a GE 1.5 MW generator.
