Design and development of real-time small-scale wind turbine simulator

Abstract

Application of power electronics in machine control facilitates emulation of practical wind turbine characteristics using electric machine. In this paper, to test and evaluate the performance of newly developed control schemes for the efficient operation of wind energy conversion system, an in-lab small-scale wind turbine simulator has been developed using a separately excited DC motor coupled to a permanent magnet synchronous generator. Steady state characteristics and dynamic behavior of the practical wind turbine are satisfactorily reproduced by the DC motor. Steady state characteristics like tip speed ratio versus coefficient of power, rotor speed versus turbine output power and dynamic response during furling mechanism at high wind velocities are emulated from the developed wind turbine simulator. The simulator system is tested in response to the wind profile data recorded in the field at the hub height of 18.5 meters. The developed wind turbine simulator can be used to represent wind energy conversion system in the process of the development of in-lab microgrid system.

Symulator turbiny wiatrowej małej mocy

“…Różne sposoby symulowania turbiny są prezentowane w publikacjach. Turbina wiatrowa jest zastępowana przez maszyny indukcyjne [1] lub maszyny prądu stałego [2,3,4] zasilane z przekształtników, które odpowiednio sterowane symulują charakterystyki turbiny. W pracy rozważono symulator turbiny wiatrowej małej mocy z asynchronicznym generatorem pierścieniowym sterowanym przez modulację rezystancji w obwodzie wirnika.…”

Small Wind Turbine Emulator Based on Lambda-Cp Curves Obtained under Real Operating Conditions

“…Several implementations of wind emulators are detailed in References [11][12][13][14][15][16][17][18][19][20][21]. Wind emulators are classified mainly according to the type of electromechanical actuator used, or by the parameters considered for the implementation of the aerodynamic model.…”

“…Wind emulators are classified mainly according to the type of electromechanical actuator used, or by the parameters considered for the implementation of the aerodynamic model. DC motors can be used as electromechanical actuators [11][12][13][14][15] because of their easy torque control through the armature current. However, DC motors present some important drawbacks such as: considerable size-power ratio, high cost, the need for maintenance, etc.…”

Small Scale Wind Generation System: Part I – Experimental Verification Of Flux Reversal Generator Block

“…Various types of electrical machines are used in small scale wind generator in the past, including permanent magnet synchronous machine (PMSM) widely, [3]- [7]. The speed control of wind energy system is achieved by adoption of diode bridge rectifier and back to back pulse width modulation based voltage source inverter [8]- [10].…”
