DAMPING ELECTROMAGNETIC OSCILLATIONS IN POWER SYSTEMS

摘要

The present invention is concerned with the damping multimode electromagnetic oscillations in electric power systems which interconnect a plurality of generators and consumers. A controller for damping such oscillations having a phasor measurement unit (PMU) and a power oscillation damper (POD) controller is described. Each oscillating mode signal is damped and then superposed in order to derive a control signal. A feedback controller is used to feedback the control signal to a power flow control device in the power system.
