VIRTUAL CONTROLLER OF ELECTROMECHANICAL CHARACTERISTICS FOR STATIC POWER CONVERTERS

摘要

The invention relates to a virtual controller of electromechanical characteristics for a static power converter that includes a PLC (23) (power loop controller), which receives, at the input thereof, the power difference (”P) between the input power (P in ) (power delivered to the converter by the primary source) and the power delivered to the grid (P elec ) and is able to modify online the parameters of the virtual inertia coefficient and the damping factor as a function of the desired response and of the grid conditions for different frequency ranges.
