摘要
Power system has become a time-delay system by applying wide area measurement signal. The delay of feedback control signal has an important influence on power system stability. In this paper, the time delay in feedback control is converted into a differential equation by using Pade approximation, thus the explicit time delay is implicated in the dynamic differential model of the system. The multi-machine power system considering the delay of feedback signal and transfer conductance is expressed as a pseudo-generalized dissipative Hamiltonian system. The wide area feedback controller with time delay in power system is achieved respectively based on the pseudo-generalized Hamiltonian system theory and controller design method in line with the properties of practical power system. The simulation result in IEEE 9-nodes system shows that the controller in generator excitation considering time delay is effective. ©, 2015, Power System Technology Press. All right reserved.
