Abstract
The traditional vector one-cycle control strategy has been improved in this article by introducing the three fictitious currents with the same voltage in power grid being added with the actual load currents, which ensures to ob-tain a lager and positive system equivalent impedance under the condition of convertor loader power unchanging and realize the four quadrant and stable operation. Based on instantaneous reactive theory method to suppress the current phase shift compensation, this paper realizes adjustable control on high-power converter power factor of the unit opera-tion and power factor. This paper sets up a 250kVA simulation model for testing the proposed method, and the simula-tion results show the feasibility of this control method.关键词
