Hamiltonian modeling of generator integrated AVR and PSS

Abstract In this article AVR and PSS are integrated with generator, and constituted the complete object-oriented model included generator and its controllers. By means of energy composition of analog circuit, controller AVR and PSS equivalent energy function descriptions are obtained. Then controller energy functions are added to the generator Hamiltonian function, and composed the total energy function of system. Furthermore, a Hamiltonian model of generator integrated AVR and PSS is derived. Finally, according to the dissipative properties of Hamiltonian model, AVR and PSS influences on generator system dissipative properties are analyzed, and PSS damping effect on port is discussed. The results show that damping characteristics reflected in the model are consistent with practical system.
