摘要：

The virtual synchronous generator technology is used to simulate the working principle of the synchronous generator, which provides the inertia and damping support for the power grid. At present, the measurement of the phase, amplitude and frequency of the virtual syn-chronous generator is used to measure the output voltage of the distributed generation system. To solve this problem, this paper proposes a virtual synchronous machine grid virtual impedance control method based on the virtual impedance calculation of virtual current in the virtual synchronous machine from the network state and the grid between the assumption of power exchange, puts forward the pre synchronization strategy based on virtual impedance, and gives the simulation results. The results show that compared with the existing methods, the proposed method is more practical and more smooth.
