Energy processing and storage system for e.g. wind power generators, has high-volt rechargeable battery reservoir working on high voltage level of frequency converter intermediate circuit and coupled with intermediate circuit

摘要

The system has a generator (2), rechargeable battery reservoir and an electronic system comprising a direct current (DC) voltage intermediate circuit. A voltage and/or main frequency converter is provided for supply of alternating voltage at output side. A high-volt rechargeable battery reservoir works on high voltage level of a frequency converter intermediate circuit (8), and is coupled with the frequency converter intermediate circuit, where the voltage level of the intermediate circuit is of specific value.
