Figure 2:
Principle structure of a monitoring and control system for a substation
The monitoring and control system can be divided into three main parts.
•
Bay level devices
•
Station communication
•
Station level devices
All three parts require specific engineering and configuration.
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 organization structure for the devices 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 = the selection of the IED that is used in the bay; it is possible to insert several
IEDs within a bay, for example, one control device and two protection relays

Standard configuration concept
The product series covers protection relays developed for the protection of medium
voltage applications. Every product has predefined application-specific software
called standard configuration that contains protection, control, supervision and
measurement function blocks and default logical connections; for more information,
