SMALL-SIZE HYDROELECTRIC POWER STATION WITH ACTION TURBINE Russian patent published in 2007 - IPC F03B13/00 E02B9/00 

FIELD: power engineering.

SUBSTANCE: proposed hydroelectric power station is designed for power generation using energy of flow spring or river. Proposed hydroelectric power station includes diversion dam, diversion cone, head, conduit, action turbine, current generator with drive. Diversion cone is made only in horizontal plane, input of bottom spillway and input of diversion cone are arranged in one plane and heat room is installed over them on top of dam, whose wall pointed to side of water storage is arranged before dam, and its lower edge is deepened to value of freezing of water storage. Action turbine is made in form of disk with volute buckets. Each nozzle of head conduit is made in for, of cone connected with gate of head conduit trough intermediate link of conduit. Additional dc generator is used as braking system to stabilize speed of action turbine. Shaft of said generator is coupled with shaft of main generator, and current from three-phase circuit of main generator is supplied to field winding of additional generator through diode bridge. Moreover, rheostat is used in field winding control circuit of main generator controlled by centrifugal pusher, for instance, of Watt system whose shaft is also coupled with shaft of main generator.

EFFECT: increased power output and provision of constant frequency of current.
