Abstract
The practical mathematic model of synchronous generator was established in the static synchronous compensator (STATCOM) of single machine infinite bus power system.Based on Hamilton energy theory,the new nonlinear controller was designed between the STATCOM which was installed in bus voltage of system and synchronous machine excitation.This controller directly uses the energy as the storage function.Compared with other nonlinear controllers,this controller has the advantage of the fast stability and the capability of quelling the disturbance.Since the nonlinear control structure retains all in this design,it does not need the linearization.The proposed STATCOM controller is more robust than linear control method.The simulation results showed that the proposed controller could faster meet generator excitation and STATCOM access point voltage transient stability than conventional PID control under the subjection to the three-phase short circuit fault.
