HYDRAULIC POWER GENERATION DEVICE AND POWER GENERATION SYSTEM
PROBLEM TO BE SOLVED: To provide a compact hydraulic power generation device capable of easily performing maintenance to dust and foreign matters while suppressing costs.SOLUTION: A hydraulic power generation device includes a water turbine 1, an electric or mechanical braking device 12 applying braking force to a rotating shaft interlocking with the water turbine 1, and a control device 100 repeating operation and releasing of the braking device 12 to increase and decrease the braking force. The control device 100 operates the braking device 12 by a first number of times (for example, three times in a case of 90% reduced by 10%), when a reduction amount from the electric power corresponding to a flow velocity of generated electric power of a generator 3 is a first value, and operates the braking device 12 by a second number of times more than the first number of times (for example, four times in a case of 70% reduced by 30%, and six times in a case of 50%), when the reduction amount of the generated electric power is a second value larger than the first value.SELECTED DRAWING: Figure 3
【課題】コストを抑えつつゴミや異物に対して保守容易な小型水力発電装置を提供する。【解決手段】水力発電装置は、水車１と、水車１に連動する回転軸に制動力を作動させる電気式または機械式の制動装置１２と、制動力が増減するように制動装置１２の作動と解放とを繰り返す制御装置１００とを備える。制御装置１００は、発電機３の発電電力の流速に対応する電力からの低下量が第１の値である場合には、制動装置１２を第１回数作動させ（たとえば、１０％低下した９０％の場合、３回作動）、発電電力の低下量が第１の値よりも大きい第２の値である場合には、制動装置１２を第１回数よりも多い第２回数作動させる（たとえば、３０％低下した７０％の場合４回作動、５０％低下した場合６回作動させる）。【選択図】図３
