Algorithms for wide area control of an excitation system are presented. The algorithms use a switched control method with speed feedback from a remote generator, and also account for communication delays. They can also reduce the negative effects of time delay. The wide area controller includes a lead-lag network. Simulation results show that the algorithms can improve the dynamic stability of an...
A rotor speed of remote generator is used as wide area measurement signal in this paper. The signal is detected and transmitted by the phasor measurement unit (PMU). The wide area signal inputs to the local power system stabilizer (PSS) to regulate the generator excitation and enhancing the power system damping. The gains of the wide area controller are determined by solving linear matrix inequalities...
