Stabilization of synchronous generators with the Hamiltonian function approach

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