Figure 2:
Principle structure of a monitoring and control system for a substation
A plant structure is used to identify each device in its location within the substation
organization. The plant structure is a logical image of the substation and the bays
within the substation. The device organization may differ from the structure of the
primary equipment in the substation.
In PCM600 it is possible to set up a hierarchical structure of five levels for the device
identification.
•
Project
•
Substation = name of the substation
•
Voltage level = identifies to which grid type or part the device belongs in the
substation
•
Bay = bay within the voltage level
•
IED = selection of the IED that is used in the bay; several IEDs can be inserted in
a bay, for example, one control device and two protection relays
2.2
Default configuration
The protection relay contains a default configuration when delivered. The default
configuration contains a simple application configuration and an LHMI configuration
which can be used as a basis when the actual application configuration is created for
the protection relay installation. The default configuration does not have output relays
connected in the application configuration, so the relay and its configuration must not
be used in installation as they are; modification of the application configuration is
always required before commissioning.
The default configuration is available for IEC 61850 Edition 2 only, though the relay
supports the IEC 61850 Edition 1 as well. For instructions on how to enable Edition
1 for the relay, see chapter IED insertion.
