Abstrakty

EN

In this paper, a nonlinear controller for VSC-HVDC transmission system is proposed. The feedback linearization based nonlinear differential-geometric techniques is used to cancel nonlinearities and decouple the input control variables. A predictive current control (PCC) method is also proposed. It can predict the current reference for the next sampling instant rapidly and accurately. Comprehensive time-domain computer simulations within MATLAB/Simulink have been carried out and the results show the feasibility and effectiveness of the proposed control scheme.

W artykule przedstawiono algorytm sterowania nieliniowego dla system przesyłu energii VSC-HVDC. W celu odprzężenia sterowanych zmiennych i eliminacji nieliniowości, zastosowano technikę nieliniowej geometrii-różniczkowej do linearyzacji sprzężenia zwrotnego. Zaproponowano także sterowanie predykcyjne prądu. Wykonane badania symulacyjne w programie Matlab/Simulink potwierdziły skuteczność algorytmu sterowania.
