Thanks for your videos 😊 I'm an Indian working in Qatar as an Electro Mechanical Technician in a food industry. In our company mostly all machines PLC controlled, so your every video very helpful for me. Your English also very easy to understand.
For my honest answer, the realpars channel is the best and most informative platform to gain knowledge about engineering and others, Realpars is really awesome, and I wish you to reach 1M+ faster...
Wicket gates will only control the speed of the turbine when the generator is not synchronized to the grid. After sync the wicket gate position is adjusted to generate more or less power, speed is consistent with grid frequency. Otherwise, great video.
It's pretty obvious that when any synchronous generator is synchronized to the grid it's speed, voltage, frequency is then fixed by that grid. Then what more water flow into the turbine will do it will produce more mechanical torque to produce more active power.
Is there a difference between this type of production vs thermal? Turbines need a real big water flow to keep running and produce, which is not the case for thermal production, because thermal production can easily be changed to allow near the exact needs of electricity. But what happen if they let too much water be spent to make the turbine turn? We loose water reserve, but what happen to electricity been produced? Do they produce too much and loose some? Or it's not the way it works? As a point of comparison, what happen if there is a sudden thunderstorm, with darker sky, meaning that a population need a sudden more electricity for lighting their house? What happen in a thermal power plan vs an hydro power plan?
As with any hydraulic system, there are flow limiters that prevent too much water from flowing to the turbines. There is a maximum rotational speed for a turbine, above which there is no additional capacity for electricity generation, but again, there are operational limits that prevent this from happening. There are some anticipatory controls that adjust output when events occur that may affect usage, but overall, power plants react to changes in demand rather than anticipate those changes. Thermal power plants can increase steam flow, while hydro plants can change water flow to spin the turbines at different speeds. In both cases, turbines can be brought online or set in an idling state to adjust to demand.

Glad to hear that, Anish! Thanks for your support.
Thanks RealPars. This lecture is quite easy-understanding and conceivable
Glad it was helpful!
Thanks realpars. this videos are amazing
Our pleasure!
thanks realpars, make lectures on instrumentation
Yes, I very nice this channel

Thanks for sharing! That's an amazing compliment!
This is really very good, thank you very much
Glad you like it!
Great explanation
Glad to hear that!
Fantastic! Would love to see more details regarding excitation equipment, turbine governors and AVRs.
Thanks for your comment and feedback! Will happily pass that on to our course developers.
good! thanks.
Thank you!
Awesome

That is true as long as the hydro generators rating is much less than the capacity of the grid (other generators paralleled to the grid).

Make sure you have water falls otherwise pray for rain
