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.
