Using the energy-based Hamiltonian function method, this paper investigates the robust nonlinear control of static var compensators (SVCs) in power systems with nonlinear loads. First, the uncertain nonlinear differential algebraic equation model is constructed for the power system. Then, the dissipative Hamiltonian realization of the system is completed by the means of variable transformation and...
This paper investigates the switched dynamic modeling and excitation control of multi-area power systems under emergency conditions, such as generator tripping and load shedding. First, a switched dynamic model for a three-machine multi-area power system is put forward. Then, the switched power system is transformed to its equivalent switched dissipative Hamiltonian system, based on which a switching...
Using the energy-based method, this paper investigates the robust control of power systems equipped with static var compensator (SVC) and nonlinear loads. First, the uncertain nonlinear differential algebraic equation model is constructed for the power system. Then, the dissipative Hamiltonian realization of the system is completed by the means of pre-feedback control. Finally, based on the dissipative...
In order to research the damage on weapon equipment by explosive shock wave, simulation experiments were carried out to study explosive impact damage on cantilever box girder. By using principal component analysis (PCA), it presented a data mining method on cantilever box girder damage. It showed that: the calculating result by using this method was agreeable with the result by using traditional method...
<para> Using an energy-based method, this paper investigates the disturbance attenuation excitation control of multimachine power system connected with constant power loads. First, a general result is presented for the disturbance attenuation control of nonlinear differential algebraic systems with dissipative Hamiltonian realization. Then, pre-feedback is employed to transform the...
