Title:
CURRENT CONTROL METHOD OF WIND POWER GENERATOR
Document Type and Number:
WIPO Patent Application WO/2016/068381
Kind Code:
A1
Abstract:
The present invention calculates control current per phase (3-phase) by using the voltage and current of output power outputted from a wind power generator, and reduces deviation between the calculated control current and a reference value to be thereby capable of following the maximum power point of a wind power generator rapidly and accurately. To this end, the present invention determines, on the basis of a converter output power outputted from a converter, an instruction current per each phase corresponding to the converter output power; and switching-controls the output current of the converter by using a command current in the form of a PWM pulse so as to follow the instruction current per phase, wherein the command current is generated per each phase of 3-phase alternating current and may be compensated for by receiving feedback of the output current per phase outputted from an inverter.
