Device for production and storage of e.g. wind power in hydro-electric power plant, has piston engine reversibly operated by gas delivered from pressure reservoir and connected with generator for power production

摘要

The device has a piston engine (20) driven by rotor blades (10) of wind wheels. A pressure reservoir (18) stores gas i.e. air, compressed by the piston engine. The pressure reservoir is connected with the piston engine. The piston engine is reversibly operated by the gas delivered from the pressure reservoir and connected with a generator (30) for power production. The rotor blades are connected with a drive shaft (14) of the piston engine. The piston engine comprises pistons arranged in a cylinder. A compression chamber is connected with the pressure reservoir. The pressure reservoir comprises an outer wall made of concrete.
