Hello to all,
I need clarification about a couple of things regarding turbogenerator's speed control.
Can you confirm the following:
1. When generator is not connected to the grig, when openning steam regulating valves and allowing more steam to turbine, turbine will rotate faster, right?
2. Generator is mechanicaly coupled with the turbine and it always rotates same speed as turbine.
3. When generator is in parallel with the grid, it cannot rotate faster or slower then 50Hz (suppose for Europe) or 3000 rpm (2 pole machine), or in another way, it will rotate the same speed as grid's frequency (for example 49.98 Hz).
4. When generator is synchronized with the grid, adjusting steam control valves cannot change the speed of the turbine/generator and it will change only output power.
I'm looking forward to your comments.
Thank you very much.
