Abstract

The stability of synchronous generator and its improvement is one of the important problems in power systems. Stability can be divided into steady state, dynamic and transient stability. The dynamic stability is studied in this paper.  DFIG capabilities will be one the effective ways to improve the stability of synchronous generator in the power network including wind generations based on doubly fed induction generator (DFIG). In this paper, a dynamic damping controller (DDC) is suggested in the reactive power band of DFIG tuned by genetic algorithm. For this purpose, two feedbacks, i.e., synchronous generator speed differences and DFIG electromagnetic torque are used. Eigenvalues and damping torque analysis are used for demonstrating the effectiveness of the suggested controller, requiring system small signal study. The simulation results verify that the controller has the ability to improve dynamic stability of synchronous generator.
