Typical control profile applications
Profile 1 Describes the ideal control characteristic curve for all consumer net-
works where an inductive cosφ is called for.
Profile 2 Suitable for consumer networks where an average cosφ =1 is to be
achieved.
Profile 3 Suitable for consumer networks where cosφ is close to 1 but overcor-
rection is to be avoided.
Profile 4 Suitable for consumer networks, as described in Profile 1, but which
have their own generating facilities (e.g. CHP units) with permanent or
frequent feed-in (regeneration) to the power supply network.
Profile 5 Suitable for generating networks, such as hydropower or wind tur-
bines, where a capacitive cosφ is called for.
