ABB Relion 615 series - Monitoring and Control System Structure

2.1 Monitoring and control system structure
The monitoring and control system for electrical substations contains a number of devices
for various purposes.
The maximum size of a project is 180 devices. However, in order to
maintain good performance and usability of the tool, it is recommended to
divide one big project into multiple smaller PCM600 projects.

Figure 3: 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.
