Embodiment 1
[0033] figure 1 Shown is the schematic diagram of the structure of the virtual synchronous generator in this embodiment, the voltage source type three-phase full-bridge topology is selected as the carrier of the virtual synchronous generator, and the parameters of the LC filter in the circuit are set: the cut-off frequency is the switching frequency One-tenth to one-fifth, and requires a fundamental frequency higher than ten times; the inductor current ripple generally does not exceed 10% of the rated current; the reactive power generated by the limiting capacitor generally does not exceed the rated power of the system 5%.
[0034] In the following, through the analysis of the characteristics of the synchronous generator model, the mechanics principle is used to study the mechanism of the synchronous generator model, and the basis for the adaptive change of the virtual moment of inertia after the disturbance is obtained. Without special circumstances, the generator rotor is a...
