PCM600 is used for various tasks in the protection relay engineering process.
- Relay engineering management
- Organizing the bay protection relays in the structure of the substation by defining voltage levels and bays below the substation. PCM600 manages the project.
- Configuring the protection relay functions (for example, protection and control functions) by using the Application Configuration tool.
- Configuring the parameters and setting values for the protection relay itself and for the process functions by using the Parameter Setting tool.
- Configuring connections between the application configuration function blocks and physical hardware inputs and outputs by using the Signal Matrix tool or the Application Configuration tool.
- Communication management
- IEC 61850 station communication engineering is done using the internal IEC 61850 Configuration tool or a separate system engineering tool such as IET600. PCM600 interacts with system engineering tools, such as IET600, by importing and exporting SCL files.
- Configuring the GOOSE receiving data connections to the protection relay's application configuration function blocks by using the Application Configuration tool and the Signal Matrix tool.
- Configuring protocol data mapping for Modbus with the Communication Management tool.
- Record management
- Generating overviews on the available (disturbance) recordings in all connected protection relays by using the Disturbance Handling tool.
- Manually reading the recording files (in the COMTRADE format) from the protection relays by using the Disturbance Handling tool or automatically by using the PCM600 Scheduler.
- Managing recording files with the Disturbance Handling tool.
- Creating recording file content overview reports for fast evaluation with assistance of the Disturbance Handling tool.
- Service management
- Monitoring the selected signals of a protection relay for commissioning or service purposes by using the Signal Monitoring tool and Event Viewer tool (including audit trail).
There are also additional functions for managing projects and organizing user rights.
- PCM600 user management
- Organizing users regarding their rights, profiles and passwords to use different tools and functions in the tools.
- Defining allowed activities for user profiles to use tools in PCM600.
Once the engineering of the protection relay is finished, the results must be written to the protection relay.
REX610 has a rear Ethernet port and a front USB port. Relay engineering can be done using both these ports. The relay supports two power-up modes, one using the auxiliary supply on the rear and another by USB. When powered up by USB, the relay works with limited functionality. The relay engineering can be done when powered up by USB. For a list of the tools supported by the rear and front ports, see Table 1.
