Combined heat and power station without
operating contact
If the combined heat and power station (1) does not
have a potential-free operating contact, it can be
connected as shown in the figure. In this set-up, a
relay is used to detect whether the generator is
active. This information is forwarded to the storage
system via a potential-free make contact in the re-
lay.
8.2.5 Recording fluctuating power of an electrical generator
• The power of an electrical generator that does not produce constant output cannot be
recorded via digital input CHP (see Recording constant power of an electrical generator
[P. 61]).
„
Instead, the electrical generator has to be integrated in the power measurement via a
separate measurement point. To achieve this, an additional power meter may be neces-
sary. The additional measurement point must be set in the commissioning assistant ac-
cordingly.
Further information on power measurement and the power meter can be
found in the power meter instructions

. These instructions explain, among
other things, the different measurement concepts and how to use multiple
power meters.
