Title: PARALLEL SMALL-SCALE HYDROELECTRIC POWER GENERATION APPARATUS HAVING FIXED PASSAGE AND OPERATED IN STAGES
Abstract:
The present invention relates to a parallel small-scale hydroelectric power generation apparatus which has a fixed passage and is operated in stages, wherein the small-scale hydroelectric power generation apparatus is installed in a pipeline of a water treatment facility, a small river, or the like, and supplies electrical power by producing electrical power through a power generation action in which kinetic energy is converted into electrical energy by using the hydraulic power (hydraulic pressure, flow rate) of water that flows through the pipeline. In order to achieve this purpose, the present invention provides a small-scale hydroelectric power generation apparatus which produces electrical power by generating electrical power using hydraulic power, wherein the small-scale hydroelectric power generation apparatus comprises: a parallel pipeline (100) having an intake pipe (110) into which water is introduced and a water outlet pipe (150) from which the introduced water is discharged, and formed by connecting a plurality of first and second straight pipes (120, 130) between the intake pipe (110) and the water outlet pipe (150); first power generation equipment (210) and the second power generation equipment (220) which are connected between the first and second straight pipes (120, 130), respectively, and into which water is introduced, and which use the introduced water to rotate a hydraulic turbine (211) and operate a power generator (221), thereby producing electricity; a control unit (400) including a first flow rate regulating unit (310) and a second flow rate regulating unit (320) which regulate the flow rates of the water introduced into and discharged from the first power generation equipment (210) and the second power generation equipment (220), thereby controlling the flow rates for power generation, the control unit (400) controls on the basis of values detected by a flowmeter (410) that is provided on water introduction sides of the first power generation equipment (210) and the second power generation equipment (220), so as to selectively operate any one among the first and second power generation equipment (210, 220) or operate the first power generation equipment (210) and the second power generation equipment (220) at the same time, according to flow rate deviations of the water introduced, by means of opening and closing any one among the first and second flow rate regulating units (310, 320) or opening and closing the first flow rate regulating unit (310) and the second flow rate regulating unit (320) at the same time.
