HYDROPOWER GENERATION SYSTEM, HYDROPOWER GENERATION METHOD, AND HYDROPOWER GENERATION PROGRAM
PROBLEM TO BE SOLVED: To provide a hydropower generation system that controls a rotation speed of a turbine in which output power becomes optimum by detecting a change in amount of water without measuring the amount of water.SOLUTION: A hydropower generation system 1 for generating power by rotating a water wheel 12 with running water flowing through a closed pipe waterway 13 includes a water pressure sensor 15 for detecting a water level change of a source 10 or a water pressure change due to intake from an intake port 11, an opening degree command control unit that adjusts and controls an opening degree of a guide vane 14 of the water wheel 12 according to the detected change in intake water, and a rotation speed command control unit for controlling a rotation speed of the water wheel 12 according to the adjusted opening degree. During a process in which the rotation speed command control unit controls the rotation speed, the opening degree command control unit outputs a command for holding the adjusted opening degree, and, when processing for controlling the rotation speed is completed, outputs a command to release holding of the opening degree.SELECTED DRAWING: Figure 1
【課題】水量を測定することなく、水量の変化を検知することで出力電力が最適となる水車の回転数を制御する水力発電システムを提供する。【解決手段】閉管水路１３を流れる流水により水車１２を回転して発電する水力発電システム１において、源流１０の水位変化又は取水口１１からの取水による水圧変化を検出する水圧センサ１５と、検出した取水の変化に応じて、水車１２のガイドベーン１４の開度を調整して制御する開度指令制御部と、調整された開度に応じて、水車１２の回転数を制御する回転数指令制御部とを備え、開度指令制御部が、回転数指令制御部が回転数を制御する処理中は、調整された開度を保持する指令を出力すると共に、回転数を制御する処理が終了したら開度の保持を解除する指令を出力する。【選択図】図１
