Hamiltonian stabilization control for hydro turbine generating units

The stability of hydro turbine generating units (HTGU) is very important for power systems as it is power supply point. Based on the Hamiltonian model of HTGU, this paper derives the additional Hamiltonian function by means of Casmir function method. Modified Hamiltonian function is a Lyapunov function at given equilibrium, and it can is used to stabilize system. Simulation results show that stabilization control is effective, and can decrease the reverse regulation of active power.
