Stabilization of synchronous generators with the Hamiltonian function approach

Abstract

Using the Hamiltonian function approach, this paper proposes an energy-based stabilizing method for a fifth-order model of synchronous generators to keep the terminal machine voltage (output) remaining at a given expected value. By constructing a Hamiltonian function as the total energy function for the fifth-order model and changing the system into a forced Hamiltonian system with dissipation, an energy-based Lyapunov function is obtained. As the result, a suitable stabilizing controller is constructed for the system. Simulation shows the effectiveness of the stabilizing method proposed in this paper.
