Wind energy system with a self-contained control device with a module for controlling active power and reactive power

摘要

An inverse rectifier (IR) (3) generates electric power (Pg,Qg) on a main line (ML) (5) linked to the IR and to a current network (CN) (9) for supplying electric power (Pn,Qn) into the CN. A tap device (7) on the ML provides its own supply (Pe,Qe) to a wind power installation via a subsidiary line (6). A control device (4) has real output (40) and wattless power (42) control modules. An independent claim is also included for a method for operating a wind power installation with a rotor to drive a generator and an inverse rectifier to generate electric power.
