high voltage direct current transmission（HVDC）; variable frequency transformer（VFT）; asynchronous power grid interconnection; experimental scheme
Power grid interconnection technology based on the variable frequency transformer（ VFT） is a research hotspot at present. The technique can solve the problems of a traditional back-to-back HVDC that has complex devices and being difficult to adjust power smoothly. The model of the VFT interconnecting two grids asynchronous is developed with Matlab / SIMULINK and the feasibility of interconnecting asynchronous grid and the case of the transmission power change are simulated. An experimental scheme based on VFT for asynchronous network interconnection is designed and an experimental platform is set up to verify the ability of interconnecting two asynchronous grids based on VFT in cases of normal operating
