The invention discloses a fan virtual synchronous machine transformation method based on a virtual synchronous machine thought, and relates to the technical field of fan virtual synchronous machines. Whether virtual synchronous machine transformation can be carried out on variable-speed fans or not is judged by analyzing operation characteristics of various variable-speed fans; and selecting the variable-speed fan capable of performing virtual synchronous machine transformation to perform strategy analysis, and setting virtual synchronous machine control according to an analysis result, so as to complete the transformation of the fan virtual synchronous machine. The new energy unit applying the virtual synchronous machine technology can change the frequency response characteristic of equipment and has the functions of adjusting system voltage and frequency, providing damping and the like by reasonably configuring control parameters of the virtual synchronous machine, thereby participating in dynamic adjustment of the system, and improving the operation safety and stability level of a power grid to a certain extent. And a new solution idea is provided for a new energy-friendly grid-connected mode by adopting a virtual synchronous generator technology.
Description
technical field [0001] The invention belongs to the technical field of fan virtual synchronous machines, and in particular relates to a method for transforming fan virtual synchronous machines based on the idea of virtual synchronous machines. Background technique [0002] With the increasing proportion of wind power installed capacity in the power system and the rapid growth of various power loads, the characteristics of power sources and power grids have undergone profound changes, and their impact on the power system has gradually become prominent. The continuous increase in the penetration rate of new energy and the proportion of DC power received has gradually reduced the installed capacity of traditional synchronous generators, the rotating reserve capacity and moment of inertia in the power system have been relatively reduced, and the inertia of the synchronous grid and the ability of primary frequency regulation have continued to decline. The frequency stability an...
