Abstract

Small signal stability enhancement in power systems is often accomplished using supplementary controls. The usual technique is to utilize a power system stabilizer to generate a control signal that is applied to the excitation of a large synchronous generator. In this paper, a different approach is taken: A control signal is obtained using estimated signals from a 'dynamic state estimator', and the supplementary control is implemented using a static VAr compensator in the transmission circuit adjacent to a synchronous generator. The details of the design of the dynamic state estimator are given. A simple example is used to illustrate the concept. The paper is intended to show feasibility of a dynamic state estimator to provide a control signal for damping enhancement.
