Electric Power Components and Systems (Impact Factor: 0.66). 02/2002; 30(2):199-216. DOI: 10.1080/153250002753427851

ABSTRACT This paper presents the analysis and design of a Direct Torque Control (DTC) of a Doubly-Fed Induction Generator applied to a wind generation system as an alternative to the classical field-oriented control (FOC) widely used in drive control. The aims of the control system are the control of the reactive power interchanged between the generator and the grid and the control of the power drawn from the wind turbine in order to track the wind turbine optimum operation point. DTC appeared as a control concept for squirrel cage motor drives. In this paper, DTC concept is applied to control a wound rotor induction generator by means of a rotor connected VSI. Torque and rotor flux control are used to control in an indirect way active and reactive power, respectively.

    • "According to the motor operating mode and in terms of available drive strategy of rotating electrical machines, Direct Torque Control (DTC) method [6], [8], [11]-[14], [20], [21] have shown that excellent fast torque response can be obtained by controlling accurately stator flux vector. Recently, DTC was applied to wind turbine control systems based on DFIG [19], [23], SEIG [2] and PMSG [10], [11], [20], [21]. "

    ABSTRACT: In this paper, the Authors present a Direct Power Control scheme of an Induction Generator (IG) associated with a wind turbine system. The turbine is used to drive the IG in order to feed an isolated DC load. It receives the required active power from the generator through a rectifier, DC bus and a boost converter. The models of the system components are developed and used in the system control scheme. Mathematical relations treating the system components are presented and studied. The generator and the turbine dynamic performances are analyzed. The simulation results of the system entire control have shown that the proposed methodology is an efficient and promising control procedure.
