Abstract
A system suitable for extracting power directly from the main shafts of slow-moving mechanical systems. The system has a closed gas circuit having a lower-pressure (LP) side and a higher-pressure (HP) side. The LP side is at a pressure substantially greater than atmospheric pressure. The system includes primary compressors coupled to the wind turbines, thermal stores coupled to heat-exchangers on both the LP and HP sides of the closed gas circuit, a secondary motor-compressor set and an expander-generator set. The system allows some degree of independence between the input power resource and the output power. When substantial wind power is present and the demand for electrical power is weak, this system can export a fraction of the energy captured and store the rest. When the wind resource is low, the system can export more power than is being collected by drawing energy from the thermal stores.
