Simulation and Experiment of Power Electronic Transformer System Based on Virtual Synchronous Motor Control
In this paper,a power electronic transformer simulation system based on virtual synchronous motor control technology is proposed,and simulation experiments are designed for the voltage and power regulation effect.The simulation system is composed of two parts:main circuit and control circuit,using high voltage and low voltage AC interface controller.On the basis of constructing the simulation system and designing the simulation parameters,the voltage support simulation experiment and frequency support simulation experiment of the high voltage AC interface and the parallel operation simulation experiment of the low voltage AC interface are carried out respectively.The results show that the simulation system of power electronic transformer designed in this paper can quickly adjust the voltage amplitude and frequency of distribution network when they fluctuate,and make the voltage amplitude and frequency return to normal.When the active and reactive power of the low-voltage AC system fluctuates,it outputs the corresponding power according to its own capacity ratio to achieve the effect of"power equalizing",which helps to ensure the stable operation of the distribution network.
