Modelling and control of a wind energy conversion system

Sarıbatır, Behçet M.
Sezer, Mesut E.
The dynamical model of a novel low power wind energy conversion system consisting of a wind turbine, an induction generator, a PWM a.c. inverter and a d.c. battery group is obtained. A feedback control law is developed to provide optimum power conversion and arbitrarily fast responses at steady-state. The feedback does not require measurement of the wind speed and therefore is suitable for real applications. The stability of the closed-loop system is analysed using a Liapunov-type practical stability criterion, and it is shown that the system remains stable for wind speed variations that are not both large and fast at the same time. Digital computer simulation studies on a 1 kVA test system verify the theoretical results.

Predicted impact of collector and zeolite choice on the thermodynamic and economic performance of a solar-powered adsorption cooling system
Baker, Derek Keıth (Informa UK Limited, 2007-04-01)
Transient thermodynamic and capital cost models for an intermittent solar-powered adsorption cooling system are presented. The models are used to predict size and cost trends as the type of zeolite and collector, and maximum zeolite temperature (T-Z,T-Max), are varied. The best synthetic and natural zeolites considered have similar performance. The minimum cost system uses a flat plate collector for T-Z,T- Max < 160 degrees C and an evacuated tube collector for T-Z,T- Max > 160 degrees C. Collector costs do...
Comparison of Matrix Converter Induction Motor Drive Control Methods
Lettl, Jiri; Kuzmanovic, Dragan; Fligl, Stanislav (2011-09-10)
In this paper, the implementation of the Field Oriented Control and the Direct Torque Control in matrix converter supplied induction motor drives is analysed, and compared with the implementation in drives supplied by the Voltage Source Inverter. The analysis is accompanied by the results of numerical simulations and experimental implementations of these two control methods.
Design and Performance Analysis of a Grid Connected PWM-VSI System
Kantar, Emre; Usluer, S. Nadir; Hava, Ahmet Masum (2013-11-30)
Pulse-width modulation (PWM) voltage source inverters (VSIs) are favorable interface devices to the power grid for renewable energy systems. This paper deals with the design of the LCL-filter and inverter for the grid-connected VSI. A complete design procedure for both reactive and passive components of LCL-filter is demonstrated with a new iterative approach in selection of the filter inductors. The design process for a two-level VSI is clearly illustrated through an example and the dynamic response is inv...
Output voltage control of a four-leg inverter based three-phase ups by means of stationary frame resonant filter banks
Demirkutlu, Eyyüp; Hava, Ahmet Masum; Department of Electrical and Electronics Engineering (2006)
A method for high performance output voltage control of a four-leg inverter based three-phase transformerless UPS is proposed. Voltage control loop is employed and the method employs stationary frame resonant filter controllers for the fundamental and harmonic frequency components. A capacitor current feedback loop provides active damping and enhances the output voltage dynamic performance. The controller design and implementation details are given. Linear and nonlinear loads for balanced and unbalanced loa...
Implementation issues of real time position estimation for induction motors using rotor slot harmonics
Ertan, Hulusi Bülent; Keysan, Ozan (2013-11-15)
In this paper, an approach to identify rotor slot harmonics, from motor currents or from induced voltage in an internal or external search coil voltage is described. The importance of this method is that instantaneous value of the rotor slot harmonics can be determined in real time. In this manner, it is possible to determine motor speed or rotor position of a motor in a short enough time, for use in vector control. This method is independent of motor parameters. Using this method an additional feedback bec...
