ANALYSIS OF THE SMALL SIGNAL STABILITY OF THE POWER SYSTEM CONNECTED WITH WIND GENERATORS

Abstract

The main objective of this thesis is to study and analyze the small signal stability of the power system
connected with wind generators, as the power generation using wind generators has gained importance in
the recent days. Here, direct drive permanent magnet synchronous generator is considered in the
investigation, and the small signal model is determined to survey the little unsettling influence
steadiness. The eigen value examination researches the dynamic conduct of Power system under diverse
modes. Thusly, by utilizing eigen esteem examination, the connection between the modes and the state
variables are acquired. Along these lines by changing the controller parameters their impact on the eigen
qualities are considered. The outcome demonstrates that the system security can be enhanced by
appropriate tuning of both generator side and grid side converter controller parameters.Small signal
model is developed for a grid connected PMSG based WECS. Eigen value analysis is performed for 3
machine nine 9 bus system using MATLAB/SIMULINK.
