Abstract :
Considering nonlinear and energy dissipation characteristics of STATCOM, realization of the generalized Hamiltonian system based on the model of system, and design nonlinear controller. This paper discussed the generalized Hamiltonian system and its realization, and established nonlinear dynamic model according to the work principle of STATCOM, completed realization of the generalized Hamiltonian system. Based on the generalized Hamiltonian system of STATCOM, the paper quoted control method of L2 interference rejection, design nonlinear controller of STATCOM which is operating in the system of single load and infinite. Digital simulation results show that the controller is very effective.
