Actually, the questions bellow were posted in the Electric power & transmission & distribution Forum, but I thought I could have more experts from this forum to answer them. I apologize for the duplicated post if this confused you.
*****************************************************************
Hopefully the following questions can be answered by those who have knowledge/experience in steam turbine operation, especially when considering combined cycle power plants.
What would be the scenario(s) when a steam turbine is manipulated to operate in a pressure control mode, and in a power control mode?
What are their advantages and disadvantages? Are they contradictory to each other?
Can the steam turbine switch mode from one to another frequently? Under what circumstances the change of mode would take place?
If the unit/plant is connected to the national grid that has power sale agreement with the grid system operator, how would the different modes affect both the grid and plant against compliances (e.g., dropping <= 4% ~ 5%, maintaining frequency 60Hz)? How would the term PFR (Primary Frequency Response) fit in the subject? How would the situation change when a gas turbine comes in to play?
Are there any books or materials you would suggest reading about this topic?
Your valuable explanations and feedbacks are very much appreciated!
