Controller Simulation of VSC-HVDC Transmission Based on Pole Placement Theory

Inhalt:
This paper focuses on the research on the transient mathematical model of VSC-HVDC transmission in a synchronous rotating coordinate system, and proposes a VSC-HVDC system controller designed by pole configuration theory. Based on the inverse system method of state feedback linearization, the inverse system model of the VSC-HVDC transmission system is deduced, and the pseudo-linear system is constructed to realize the decoupling of the active power and reactive power of the VSC-HVDC transmission system. Finally, the pole configuration method is used to synthesize the pseudolinear system, and the corresponding controller is designed. The simulation results show that the controller designed with pole placement method based on the inverse system theory has excellent dynamic response characteristics under large disturbances.
