GRID MONITORING RELAY:
Denition and terms:
C&I
XOLTA C&I stands for XOLTA Commercial and Industrial
systems (BAT-79, BAT-80). It could be single rack or multirack
installationatspeciedlocation.
Grid code
Gridcodesdenerulesthatgenerationsystemsmustobey
to gain access to the grid. In particular, these rules regulate
behaviorintheeventofgriductuations.
The grid operator determines the behavior of systems in the
event of undervoltage, overvoltage, and frequency deviation,
andalsodenestheconnectanddisconnectconditions.
NA Schutz relay (grid feeding monitoring relay)
NA (Netz und Alagenschutz). It is a device that monitors and
detects unusual events in the public grid and automatically
disconnects and reconnects the battery system following
specicgridcodes.
Point of common coupling (PCC)
Point of Common Coupling or PCC - means the point where
the Generating Facility’s (e.g. battery system) local electric
power system connects to the Utility’s Electric System.
Installation:
Introduction
Decentralized energy generation systems, such as battery
systems generate decentralized electricity that is fed into the
power grid. The feed-in must be controlled in order to ensure a
stable frequency and voltage grid quality. Each decentralized
energy generation system must be monitored with grid and
system protection – NA Schutz protection for short.
The inverters of the Xolta C&I are setup to follow the spe-
ciccountry/regiongridcode(e.g.overorunderfrequency
response, etc.), but for full grid code compliance, they require
a single and external NA Schutz relay for entire XOLTA C&I
installation. NA Schutz is monitoring grid voltage at the point
of common coupling (PCC) and disconnects or reconnects
thesystemaccordingtothespecicgridcoderequirement
NA Schutz installation:
NA Schutz recommendation
XOLTA is recommending the following two brands of NA Schutz
for XOLTA C&I installations (Table 1). However, other suppliers
ofNASchutzarepossibleifproductfollowsspecicgridcode
requirement. There is no requirement to have a version with
Modbus connection.
Thegridcodesthataresupported(certied)fortheseNA
Schutz (as it is on 22.06.2023) are presented in Table 2.
However, please note that all devices’ settings can be para-
metrized to follow other grid code requirements (refer to their
Manual documents for the latest list of available grid codes).
