“…For the valueβ=0, the graph ofC p (λ), given in Fig. 2, is plotted using expression (6).The conversion device extracts a power less than the theoretically recoverable power due to non-zero speed of air masses upstream of the turbine. This presents a theoretical limit called the Betz limit which corresponds to a C pmax [10,14].…”

“…Many devices exist and, mostly, they use synchronous and asynchronous machines. The control strategies of these machines and their possible network connection interfaces must be able to capture maximum energy over a wider range of variation of wind speeds, to improve the profitability of wind turbines [6]. The studied system here consists of an aero generator three-bladed, with horizontal axis, connected to the network by the dual stator induction generator (DSIG).…”

This paper deals with the modeling and the control of a dual stator induction generator (DSIG) integrated into a wind energy conversion system with a variable speed wind turbine. DSIG is increasingly used because of its advantages in better reliability and supply division. It consists of two fixed three-phase stator windings displaced with an electrical angle . To minimize the harmonic distortion (THD), the objective of this work is to study the influence of the angle between these two stator windings on the grid generated current quality. To improve the performance of the system, the proposed control is demonstrated through an illustrative simulation.

“…Abdel-halim et al [5] proposed a technique for the rotor injected voltage of a DFIG such that the wind turbine tracks the maximum wind energy, and at the same time the stator current is kept at unity power factor. Boumassata et al [6] proposed a system constituting of a DFIG using a controlled cycloconverter in the rotor aiming at improving the maximum power point tracking. Abdel-halim, et al [7,8] suggested a method of controlling the induction generator such that the driving windturbine follows the point of maximum wind power.…”

In this research, a cage induction generator has been linked to the grid and driven with a wind-turbine to generate electrical power. The cage generator has been used in place of the costly slip-ring generator. The performance characteristics of the cage induction generator have been ameliorated through changing its number of poles to comply with the level of the wind speed to maximize the mechanical power extracted from the wind. Pole changing has been achieved employing pole-amplitude modulation technique resulting in three sets of pole numbers. The results proved the feasibility and effectiveness of the suggested method, as the proposed technique led to driving the generator, and consequently the wind-turbine at speeds close or equal to those satisfying the optimum tip-speed ratio which corresponds to the point of maximum mechanical power.

“…In the recent years, renewable energy systems have attracted the great interest because conventional sources of energy are limited and a number of problems associated with their use, like environment pollution, large grid requirements etc. Governments of the whole world are forced for the alternative energy sources such as wind power, solar energy and small hydro-electric power (Boumassata et al, 2013). Unlike the electricity from fossil-fuel-powered sources, Wind energy becomes the least cost renewable energy sources.…”

Purpose This paper presents the mathematical models of Static Kramer Induction Generator (SKIG) that greatly improves its performance to be competitor for wind energy and hydraulic power generation. Design/methodology/approach Two models of control strategies are proposed, the first is to control the imposed rotor voltage, thus an angular relationship between stator voltage and rotor voltage vectors over the operating speed range is established. which may be achieved by regulating the slip of the machine through the Grid Side Converter (GSC) to fix the operating technique. The second one is to control the rotor current via GSC. GSC is a PWM Voltage Source Converter Findings A comparison between the two techniques is given and very good matching is obtained. Both control strategies can be achieved in terms of the GSC firing angle as shown. In addition to the greatly improved power factor. The paper illustrates the availability of extending the operating speed range up to twice of the synchronous speed, however, the speed range must be limited by the GSC ratings to achieve the slip recovery advantage of lowering the interfacing grid converter rating in analogy the system may be applied for electric drives as well. Originality/value The operational advantages of the proposed system can be summarized as follows: 1- The system is capable of increasing the operating speed range up to twice of synchronous speed. For slip energy recovery system the required super synchronous speed range is given by 1/3 synchronous speed. 2- The system provides significant improved power factor controllability over the operating speed range. 3- The system provides controllability for either excitation rotor voltage or rotor current through the firing angle control of the grid side converter. 4- Near constant stator and rotor currents overall the speed range. 5- Near constant magnetization current. 6- Higher efficiency and reliability.
