Application example of combined heat and power/hydro power plant as distributed power generation coupled into the utility network
Standard configurations C and D are intended to be used in
synchronous power generator application where the protection
coverage is a generator, field excitation system and primary
mover. A typical application example is parallel connected
diesel or gas generators with a common step-up transformer
but it can also be a generator in block connection with a
transformer. In medium-size power generator applications
independent and redundant protection system can be a
requirement or the protection system as a whole may require
more than one protection relay in one set-up. Various
recognized earthing principles exist and typically earthing
selection depends on the complete system requirements where
the generator is located. The earth-fault protection depends
mainly on the used earthing principle.
