The PMSG-Based Wind Power System and Its Weak-Grid Operation Control
摘要
The typical structure of the PMSG-based wind power system is shown in Fig. 7.1. In this case, the generator-side converter is connected to the generator stator and realises generator control by regulating the stator current. The grid-side converter is used to control the DC-bus voltage and feeds the full power into the grid to achieve decoupled active and reactive power control. Between the grid-side converter and the grid there is usually a filter structure to suppress the harmonic currents caused by the converter.
