Excitation (magnetic) - Wikipedia

The process of generating a magnetic field by means of an electric current is called excitation. Field coils yield the most flexible form of magnetic flux regulation and de-regulation, but at the expense of a flow of electric current. Hybrid topologies exist, which incorporate both permanent magnets and field coils in the same configuration. The flexible excitation of a rotating electrical ...

Preparing to synchronize a generator to the grid

We have two generator of 15MW having 11KV voltage which runs in parallel.when load requirment exceeds 30MW we have to syncronised generators with grid which is 132/11KV.When grid runs in parallel with generator the average powerfactor of grid is poor due to which we have to pay baby penalty to EB.But when load puts on grid indipentantly running as well as average powerfactor is good.Please ...
