Abstract

Abstract:

Aiming at the problem that the control delay affects the compensation effect of STATCOM in dynamic reactive power compensation and harmonic control, such as current detection, sampling and digital controller discretization, the low-voltage three-phase bridge STATCOM in coal mine is taken as the research object. Based on the analysis of its basic working principle and the establishment of control system architecture, the causes of STATCOM control delay are discussed, and the influence of control delay is quantitatively analyzed. The STATCOM control delay compensation method based on selective control is studied and proposed. The algorithm compensation and periodic compensation are organically combined by the judgment method of hypothesis test. The fixed-time algorithm compensation has faster tracking speed in transient state, and the periodic compensation has higher control accuracy in steady state. Finally, the effectiveness of the proposed method is verified by Matlab / Simulink simulation and experimental platform.
