Abstract

Cross-regional power supply and regional power grid interconnection is the future development of the power grid. At present, AC and DC asynchronous interconnection methods have disadvantages of complicated control and poor system stability. A grid interconnection solution based on variable frequency transformer (VFT) is a possible solution. Based on the introduction of the basic structure and operation principles of VFT, this paper presents a new structure in which a VFT and a drive motor share a core of electrical steel. The new structure VFT is modeled and analyzed by finite element analysis. Through the analysis of the air gap magnetic field of the VFT, the coupling analysis and operating characteristics analysis of the power winding and the control winding verify the design.
