Characteristic Analysis of a Wind Power System with Doubly Fed Induction Generator in Considering of the Tower Shadow Effect

摘要

Characteristic analysis of a 2MW wind power system with doubly-fed induction generator (DFIG) is carried out. In the analysis, tower shadow effect that occurs in 'case "of downwind turbine remarkably is considered.Tower shadow effect is modeled as a variation of the output power. Stator-field-oriented vector control is applied to the control system in order to compensate the variation.Furthermore, influence of the moment of inertia against the rotor input in considering-of the tower shadow effect is clarified by computer simulation.
