To add any one watching. This is a Kaplan Turbine. It is a reaction turbine, the water flowing over the blades moved the blades , the opposite of a ship’s propeller where the blades push the water. So high flow, low water pressure , called head, because the dam is not high. My dam is 100 feet high and is a Kaplan. For very high dams you use an Impulse turbine called a Pelton. Imagine a garden hose solid stream hitting the blades of a pin wheel. No wicket gates, a valve regulates the flow in the hose nozzle. Other dams use a Francis Turbine , more pressure than Kaplan , less than Pelton. The main regulation of speed when under no load is the wicket gates signaled by the governor. When under load the governor controls the power produced by moving the same wicket gates but the speed does not change it stays at grid synchronous speed. The blades on the propeller , called a runner in a Kaplan Turbine, also move Under governor control but this is more fine tuning to increase efficiency as the water level upstream changes or unit is not running at design load.

Always crazy to realize how truly ancient these power plants are. Similar to how NASA today, builds spacecraft designed in the 2000s with at the time 20 year old tech, witch makes them nearly 50 years old. This power plant was first commissioned in the 80s or so, at witch point the plans where probably already 20 years old and at the time those plans where based on technology from 20 years ago. So basically the powerplant you are running today was in one form or another designed in the 1940's and its till running today. I myself am working on hydropower plants, and we have a backup generator that was cast by a company that went out of business in the 1850s. This thing is still standing today (granted only for use in emergency's) in our mashineroom over 150 years later.

I am 41 years old and have always been fascinated with hydroelectric dams having vacationed in TVA country all my life. These videos are absolutely incredible (and just a little bit terrifying). I can't thank you enough Chris. One question... does the outflow water level tend to be fairly close to the turbine blades at all times? I'm trying to understand how in certain parts of the video the water on top of the turbine blades looks stationary.

Interesting structure, and it's cool to be able to see inside. I've only been inside of the semi-spiral scrollcase of a new hydro dam I worked on a few years ago, and it's interesting to see how much the hydraulic design has changed in the century+ of time between them. My province has quite a few stations from the early 1900s, and I'm hoping I'll get to do some interesting inspections throughout my career!

@tedrex8959 3 жыл бұрын

@@Physicsduck Sadly I can attest to the fact that boats do not always stay afloat. I was trapped in the cabin of one that sprung a leak and almost drowned. Luckily I had a belt with me that allowed me to haul stuff out of the way so I could swim down and escape. Drowning is one of the more common forms of accidental death, I am a big coward who likes to work out the odds, so learning to swim to keep me and people with me safe with no extra equipment seemed like a good use of my time. (All of which is a very long way of saying, please learn how to swim. I'm sure I am not the only one who would hate it if something happened to you.)

Hydroelectric is hydroelectric. By scale, this is a tiny unit. The various dams I've worked on to rebuild turbine units, the headstock (intake) range from 60-120' from floor to ceiling. The draft tube is where I really like to be. Avg 300ft below the surface of the headwater. It makes you feel sooo tiny.
