Abstract

See full text

A system for storing and outputting thermal energy and a method for operating the system are provided. The system operates according to the Brayton cycle, wherein a heat accumulator is charged by a compressor and a cold accumulator is charged by turbines. The cycle is reversed for discharging. In addition, the cold accumulator supplies a cooling circuit, which provides the cooling for a superconducting generator by a cooling unit. A favorable generator weight can thereby be advantageously achieved in particular for wind turbines, because the generators are limited regarding the weight thereof due to being housed in the nacelle of the wind power plant. Thus, advantageously higher power can be converted in the wind power plant.
