Abstract :
The aim of this paper is dynamic modeling and analysis of STATCOM for a single-machine infinite-bus (SMIB) power system. Also the study the applicability of PID type in dynamic performance enhancement with eigenvalue analysis is shown. Non-linear and linear models of a single machine have been derived. The STATCOM is modeled as a reactive current source with a time delay. A comparative study for two control inputs, one in the speed loop and the other in the voltage loop, for STATCOM controller using eigenvalues analysis is shown.
