そして、補機の駆動源に電気、油圧の両方が用いられると、操作、保守、メンテナンスが複雑になるという問題点があった。 And, when both electricity and hydraulic pressure are used for the drive source of the auxiliary machine, there is a problem that operation, maintenance, and maintenance become complicated.
また、補機を駆動する油圧ユニット、水圧ユニットが設けられる場合、油圧ポンプ、水圧ポンプが電動モータで駆動されると、油圧ポンプ、水圧ポンプを駆動するのに多くの電力を必要とし、発電効率が低下する。 In addition, when a hydraulic unit and a hydraulic unit for driving auxiliary equipment are provided, if the hydraulic pump and the hydraulic pump are driven by an electric motor, a large amount of electric power is required to drive the hydraulic pump and the hydraulic pump.

A hydraulic pump that discharges the hydraulic water guided to the pump and a pump driving water turbine that drives the hydraulic pump, and the pump driving water turbine is rotated by hydraulic power.
本発明によると、ポンプ駆動用水車が水力によって水圧ポンプを駆動することにより、水圧ポンプを電動モータ等によって駆動する必要がなくなり、水圧ポンプを駆動するのに必要な電力を極めて低く抑えることができるので、発電効率を高められる。 According to the present invention, since the pump-driven water turbine drives the hydraulic pump by hydraulic power, it is not necessary to drive the hydraulic pump with an electric motor or the like, and the electric power required to drive the hydraulic pump can be kept extremely low. Therefore, power generation efficiency can be increased.

こうして取水ライン１１と上流側水圧配管１２と下流側水圧配管１５は、ダム１から、発電用水路とは別に補機を駆動させるための水を流下させる水路を構成する。 In this way, the intake line 11, the upstream hydraulic pipe 12 and the downstream hydraulic pipe 15 constitute a water channel through which water for driving the auxiliary machine flows down from the dam 1 separately from the power generation water channel.
ポンプ駆動用水車１４は、上流側水圧配管１２と下流側水圧配管１５の間に介装され、この間を通過する水流によって駆動される複数の羽根を有し、これらの羽根を介して水の位置エネルギを、回転運動のエネルギへ変換して回転作動する。 The pump driving turbine 14 is interposed between the upstream hydraulic pipe 12 and the downstream hydraulic pipe 15 and has a plurality of blades driven by a water flow passing between the upstream hydraulic pipe 12 and the position of the water via these blades.

The pump-driven water turbine 14 is rotated by the water flow passing through it. The water that has passed through the pump driving water turbine 14 flows down through the downstream hydraulic pipe 15.

水圧ポンプ１６の吸込口は、ポンプ吸込ライン１３を介して取水ライン１１に接続され、ダム１からの余剰水が取水ライン１１とポンプ吸込ライン１３を通って水圧ポンプ１６に導かれる。 The suction port of the water pressure pump 16 is connected to the water intake line 11 via the pump suction line 13, and surplus water from the dam 1 is guided to the water pressure pump 16 through the water intake line 11 and the pump suction line 13.
ポンプ吸込ライン１３は取水ライン１１と水圧ポンプ１６の吸込口を連通する。水圧ポンプ１６は、その回転によってポンプ吸込ライン１３を通って導かれる水を吸込み、加圧された水を作動水として高圧水供給ライン１８へと吐出する。 The pump suction line 13 communicates the intake line 11 and the suction port of the hydraulic pump 16. The hydraulic pump 16 sucks water guided by the rotation through the pump suction line 13 and discharges the pressurized water to the high-pressure water supply line 18 as working water.
高圧水供給ライン１８は、水圧ポンプ１６から吐出される作動水を、高圧水供給ライン１８を通して調速機２０、取水ゲート開閉装置２２、入口弁調整装置２１、調速機１７、流入ゲート開閉装置２３の各水圧アクチュエータに導く。 The high-pressure water supply line 18 supplies the operating water discharged from the hydraulic pump 16 through the high-pressure water supply line 18 to the governor 20, the intake gate opening / closing device 22, the inlet valve adjusting device 21, the governor 17, and the inflow gate opening / closing device. It guides to each hydraulic actuator of 23.
調速機２０、取水ゲート開閉装置２２、入口弁調整装置２１、調速機１７、流入ゲート開閉装置２３から排出される水は、排水ライン１９を通って流下する。 Water discharged from the governor 20, the intake gate opening / closing device 22, the inlet valve adjustment device 21, the governor 17, and the inflow gate opening / closing device 23 flows down through the drainage line 19.
以上のように、水力発電システムは構成され、次に作用を説明する。 As described above, the hydroelectric power generation system is configured, and the operation will be described next.
ダム１に貯められた水は、上流側水圧配管２を通って流下し、発電用水車４に導かれる。発電用水車４がこれを通過する水流によって回転作動し、発電機１０を回転駆動し、水力発電が行われる。発電用水車４を通過した水は、下流側水圧配管３を通って流下する。 The water stored in the dam 1 flows down through the upstream hydraulic pipe 2 and is guided to the power generation turbine 4. The power generation water turbine 4 is rotated by the water flow passing through it, and the generator 10 is rotationally driven to perform hydroelectric power generation. The water that has passed through the power generation water turbine 4 flows down through the downstream hydraulic pipe 3.
一方、ダム１からの補機を駆動するための水は、取水ライン１１と上流側水圧配管１２を通って流下し、ポンプ駆動用水車１４に導かれる。ポンプ駆動用水車１４がこれを通過する水流によって回転作動し、水圧ポンプ１６を駆動する。 On the other hand, the water for driving the auxiliary machine from the dam 1 flows down through the intake line 11 and the upstream hydraulic pipe 12 and is guided to the pump driving turbine 14. The pump-driven water turbine 14 is rotated by the water flow passing through it, and the hydraulic pump 16 is driven.
こうして、ポンプ駆動用水車１４が水力によって水圧ポンプ１６を駆動することにより、水圧ポンプ１６を電動モータ等によって駆動する必要がなくなり、水圧ポンプ１６を駆動するのに必要な電力を極めて低く抑えることができるので、発電効率を高められる。 In this way, when the pump-driven water turbine 14 drives the hydraulic pump 16 by hydraulic power, it is not necessary to drive the hydraulic pump 16 by an electric motor or the like, and the electric power necessary to drive the hydraulic pump 16 can be kept extremely low.

調速機２０、取水ゲート開閉装置２２、入口弁調整装置２１、調速機１７、流入ゲート開閉装置２３は、水力発電システムの作動を制御する補機として設けられる。これらの補機は、水圧ポンプ１６から高圧水供給ライン１８を通して導かれる作動水によって作動する。これにより、補機を電磁アクチュエータや油圧アクチュエータによって駆動する必要がなくなり、補機を駆動するのに必要な電力を極めて低く抑えることができるので、発電効率を高められる。 The governor 20, the intake gate opening / closing device 22, the inlet valve adjusting device 21, the governor 17, and the inflow gate opening / closing device 23 are provided as auxiliary devices that control the operation of the hydroelectric power generation system. These auxiliary machines are operated by working water led from the hydraulic pump 16 through the high-pressure water supply line 18. As a result, it is not necessary to drive the auxiliary machine with an electromagnetic actuator or a hydraulic actuator, and the power required to drive the auxiliary machine can be kept extremely low, so that the power generation efficiency can be increased.
補機を駆動する作動水は、全て取水ライン１１から取り込まれ、補機を駆動した後は、排水ラインから流下する作動水を冷却する必要がなく、油圧ユニット等に設けられる冷却設備が不要になる。 All the working water that drives the auxiliary equipment is taken from the water intake line 11, and after the auxiliary equipment is driven, it is not necessary to cool the working water flowing down from the drainage line, and cooling equipment provided in the hydraulic unit or the like is unnecessary. Become.
油圧アクチュエータに関連する油圧ユニット等が設けられないため、油漏れによる環境汚染の心配がなく、防火、防暴の設備を設ける必要がない。 Since a hydraulic unit or the like related to the hydraulic actuator is not provided, there is no fear of environmental pollution due to oil leakage, and it is not necessary to provide fire prevention and violence equipment.
補機を駆動する電動アクチュエータが設けられないため、漏電の心配がなく、引火防止等の設備を設ける必要がない。 Since the electric actuator for driving the auxiliary machine is not provided, there is no fear of electric leakage and there is no need to provide facilities for preventing ignition.
また、補機の駆動源が水圧に統一されることにより、操作性、保守、メンテナンス性の向上がはかられ、維持コストを低減できる。 In addition, since the drive source of the auxiliary machine is unified to water pressure, operability, maintenance, and maintainability are improved, and maintenance costs can be reduced.
以上のとおり、本実施の形態では、水力によって回転作動する発電用水車４を備え、この発電用水車４によって発電機１０を駆動する水力発電システムであって、水圧アクチュエータによって水力発電システムの作動を制御する補機（調速機２０、取水ゲート開閉装置２２、入口弁調整装置２１、調速機１７、流入ゲート開閉装置２３）と、この補機に導かれる作動水を吐出する水圧ポンプ１６と、この水圧ポンプ１６を駆動するポンプ駆動用水車１４とを備え、このポンプ駆動用水車１４を水力によって回転作動させる構成とする。 As described above, in the present embodiment, the hydraulic power generation system 4 is provided with the power generation turbine 4 that is rotated by hydraulic power, and the power generation turbine 4 drives the generator 10, and the hydraulic power generation system is operated by the hydraulic actuator.
