Research on Topology and Performance of Grid-Connected Inverter for Direct-Driven WGS

Abstract:

It is necessary that the grid-connected inverter was set up in wind generation system (WGS), in order to convey energy generated in WGS to the electrical grid. There are many sorts of inverters, but only two sorts of inverters suit wind generation system, which are current-source and voltage-source inverter, and only the latter is being widely used. The configuration, principle, control and characteristic of the two inverters were analyzed. Results have shown that, voltage-source grid-connected inverter has been the core of the commutation control configuration of direct-driven WGS, which is decided by the peculiarity of itself.
