Nonlinear and Independent Control of Active ...

This article about decentralized control wiring rotor induction machine with two pieces of three-phase bridge converter with DC link connected between the rotor and network will discuss and independent control of active and reactive power of induction generator with double feed “DFIG” which is used for electricity generation in variable speed wind power plants, is considered. In this article with use of feedback linearization method “the controller is designed with the goal of independent control over the stator active and reactive power”. That works in the high and low speed synchronous. As regards stator voltage measured by the sensor, however, the stator flux should be estimated by means of tracking stator voltage (instead of tracking flux). After the proof of the relations and equations required in centralized control, a model representing separate active power and reactive power control, in the induction generator DFIG is simulated in Matlab-Simulink environment and the results have been reviewed.
