Abstract
Power system dynamics around an operating point can be represented by a multi-input linear time invariant state equation X=AX+BU. It has been known that the closed-loop poles of this system can be exactly assigned to desired locations when all the the state variables are available for feedback. This can be achieved either by a unity-rank feedback controller or by a controller of unrestricted rank. However, the solution is not unique, i.e. more than one controller can be designed to achieve the same objective as far as pole locations are concerned. This design freedom can be used to satisfy some other design criterion without altering the desired pole locations.
In this thesis, this design freedom is used to minimize the sensitivity of the assigned closed-loop poles of the system with respect to variations in the matruix A (due to changes in operating conditions of power system). In other words, pole assignment and sensitivity analysis are combined. This design procedure is first applied to a simple power system (third order model) representing a synchronous machine connected to an infinite bus through a transmission line.
The procedure is then extended to include the effect of an automatic voltage regulator (A.V.R.) - fourth order model. The controller designed in this case is then applied to higher order systems taking into account the effect of type-1 excitation system and mechanical mechanism.
A comparison with a unity-rank controller and single-input controllers is carried out to show the superiority of the proposed controller.
