Power system stabilizers design using optimal reduced order models. II. Design

For pt.I see ibid., vol.3, no.4, p.1670-5, 1988. The design of power system stabilizers using an optimal reduced-order model whose state variables are torque angles and speeds is examined. Two systems, a one machine-infinite bus system and a multimachine system, are considered. A controller, which is a linear feedback of these variables only and hence accounts for the realities and constraints of electrical power systems is designed based on the reduced-order model. The results obtained with the study systems demonstrate that the proposed controller is very effective.<
