Abstract :
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 (LMI). The LMI solving method is introduced for the wide area control of power systems. A proportional plus derivative network is used to compensate the communication delay. Kundur´s four-machine two-area system is used to test the performance of the wide area damping control. The simulation results show that the wide area control can improve power system stability.
