Low-Speed Sensorless Control of DFIG Generators Drive for Wind Turbines System

چکیده
In this paper, we present a nonlinear robust control of active and reactive power by the use the PI regulators control (FOC) a Double-Fed Asynchronous Generator (DFIG) system incorporated in a windturbine. The power transfer between the stator and the network grid is carried out by acting on the rotor via a bidirectional signal converter. Initially, a control strategy of the MPPT-DFIG is presented. Thereafter, a new control technique for wind systems is presented. This control technique is based on an SVW placement control strategy. The overall stability of the system is shown using SVW block. The performance and robustness are analyzed and compared by simulation based Matlab / Simulink software.

Nowadays, the doubly-fed induction generators (DFIGs) based wind turbines (WTs) are the dominant type of WTs connected to grid. Traditionally the back-to-back converters are used to control the DFIGs. In this paper, an Indirect Matrix Converter (IMC) is proposed to control the generator. Compared with back-to-back converters, IMCs have numerous advantages such as: higher level of robustness, re...
