I have a query about the power factor change in a power plant. There are 8 gas engines in parallel. When 1 engine runs with a set p.f of .8 the output at the delivery after transformer (11/132kv, step up Ynd1) is almost same. But when all generators are running with each having .80 p.f the p.f...

Do power plant generators regulate the output voltage the same way a car alternator regulates its output voltage. Or do power plant regulators control the output by regulating the rotation speed of the generator.

Can anyone tell me who is a Mechanical Engineer and works in a Nuclear Power Plant, just what their daily duties include? How they like the work environment and such. I'm interested in knowing because as a student, my university has a Co-op program. Recently, I sent out my resume to FirstEnergy...
