The monitoring and control system can be divided into three main parts which require specific engineering and configuration.
- Bay level devices
- Station communication
- Station level devices
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
