How would your power plant be involved in a cold start of the grid and have you ever participated in one before?
Well a complete cold start wouldn't really ever happen in my current position. But, plenty of equipment is taken offline/bypassed during maintenance.Getting things going from cold, in my experience, is about going slow and steady. What that might look like though? Depends on the system. We have several turbines, boilers, and a HRSG (think a combination of a turbine and boiler in one big box). So most things are brought up slowly if thats an option. That might mean bringing the fire rate up by X% every X minutes. How you bring XYZ up from cold is a commonly asked question on my state licensure exams actually.
Thanks for the detailed answer. Coming back up slow and steady seems like the right thing and it makes sense that each piece of equipment would have its own procedures for coming back up.
I was reading somewhere about a grid failure in the midwest and how it was really difficult to bring the whole grid up from cold and they had a special kind of power plant that basically, I can't remember the details, but it was a very, very small power plant which did the initial start and everything else kind of came back up from that one.
