Abstract: A fault-tolerant method and system of controlling electromechanical oscillations in a power system. The system of controlling comprises at least one phasor measurement unit (58, 60, 62, 64) obtaining phasor data signals including oscillating mode signals, at least one wide area control system (66) receiving the phasor data signals from the phasor measurement unit, and at least one actuating device (80, 82, 84) for receiving a control signal from the wide area control system. Specifically, the wide area control system performs the fault tolerant control method of the present invention, wherein information about each critical oscillatory mode of an oscillation is extracted from a model, selected residues for each critical oscillatory mode are grouped together, and a partial damping controller is designed for each selected critical oscillatory mode using residues from the same group. A multivariate damping controller is produced and applied to one or more actuating devices in the power system to control electromechanical oscillations.

Abstract: The present invention is concerned with the combined voltage or power flow control and damping of electromechanical oscillations in an electric power system (2) by Flexible AC Transmission System (FACTS) devices (20) or High Voltage DC (HVDC) transmission devices. To this end, information about a state or operating point of the power system is generated from suitable second system signals (y 2 ) and a control parameter (cp) of a FACTS controller (1) is derived therefrom. The control parameter and a first system signal (y 1 ) are used in the calculation of a control command (u) defining the settings of the FACTS device. Following a change in the state of the power system such as a change in the topology of a transmission network, poorly damped or even unstable oscillations are avoided by appropriate re-tuning of the control parameter of the damping or stabilizing equipment.

Abstract: The present invention is concerned with a faster response and an increased accuracy in power system protection. According to the invention, a fault, instability or other contingency potentially requiring some protective action, such as line tripping or load adaptation, is detected in a fast and precise way by tracking a non-frequency-selective evolution of a physical parameter (R, L) in time domain, preferably with adaptive filters. By reverting to a physical parameter having an imminent physical significance, no additional analysis is required to divulge a fault or contingency, hence the speed of fault detection increases. Due to the skin affect in electrical conductors, a time domain analysis covering a broad range of frequencies includes more information than an analysis confined to the fundamental or line frequency, hence the accuracy of the fault detection increases.
