State Observer for Doubly-fed Induction Generator
Journal Title: Power Electronics and Drives - Year 2017, Vol 2, Issue 2
Abstract
In the paper a new state observer for doubly-fed generator has been proposed. In the new approach an extended mathematical model of the doubly fed generator is used to form equations of the introduced z type observer. Stability of the observer has been verified through poles placement analyses. The active and reactive powers of the generator are controlled by a nonlinear multiscalar control method. Simulation and experimental results are presented and used to evaluate the quality of estimation of the observer.
