摘要：

This paper presents time-delay robust damping control for inter-area oscillation in power system by using remote signals from wide-area measurement system (WAMS). To ensure satisfactory performance, variations of operating condition and time delay are considered. Design of damping controller is formulated as time-delay output-feedback control problem. Time-delay power system model is constructed by system identification and Pade approximation. Based on the time-delay system model, robust damping controller is designed employing mixed-sensitivity H. control theory and pole placement approach in the linear matrix inequality (LMI) framework. This method is applied to design damping controller for prototype power system reinforced with static var compensator (SVC). Damping performance of the controller is examined in the frequency and time domains for various operating scenarios. The controller is found to be effective in damping inter-area oscillation and robust to variations of operating condition and time delay. Copyright (C) 2008 John Wiley & Sons, Ltd.
