| Mar 10, 2017 at 2:37 | comment | added | mbrig | @ThePhoton A lot of hydro plants can adjust angle of the blades on the turbines (very slightly) when they need to do small adjustments. Or have a bypass valve that diverts a little of the water (which I think is pretty similar to what coal and gas do, except with a steam bypass?) | |
| Mar 9, 2017 at 17:26 | comment | added | The Photon | There's a reason why hydro is preferred for large steady loads and coal and gas are used to keep things in sync under variable loads. For hydro, throttling probably means restricting the water inflow somehow. | |
| Mar 9, 2017 at 17:21 | comment | added | Trevor_G | @ThePhoton, thanks for that, I can picture that throttling with a steam driven machine, any idea how they "Thottle" a hyrdo-electric turbine that delicately? The masses and inertias involved in all this are quite mind boggling. A much under-rated science me thinks. | |

| Mar 9, 2017 at 17:11 | comment | added | The Photon | @Trevor, each generator operator matches it by throttling their generator up or down to get it matched before connecting to the grid. To keep the frequency at 60.000 Hz (or 50.000) several the operators adjusts their throttle in cooperation to maintain the frequency. | |
