18. Self-supervision

The device's built-in self-supervision system continuously
monitors the state of the device hardware and the operation of
the device software. Any fault or malfunction detected is used
for alerting the operator.
Self-supervision events are saved into an internal event list
which can be accessed locally via the user interface on the
device's front panel. The event list can also be accessed using
the Web-browser based user interface or PCM600.

19. Access control

To protect the device from unauthorized access and to maintain
information integrity, the device is provided with an
authentication system including user management. Using the
IED User Management tool in the Protection and Control IED
Manager PCM600, an individual password is assigned to each
user by the administrator. Further, the user name is associated
to one or more of the four available user groups: System
Operator, Protection Engineer, Design Engineer and User
Administrator. The user group association for each individual
user enables the use of the device according to the profile of the
user group.

20. Time synchronization

The device supports the Ethernet-based SNTP and IRIG-B-
[1]
based time synchronization methods with the time-stamping
resolution of 1 ms. This information can be accessed in the
COM600 device alarms and the event display pages.

21. Integration into switchgear

The 630, 620 and 615 series protection relays can be directly
mounted in a medium-voltage metal-clad switchgear.
Additionally, the COM600 hardware is based on the ruggedized
mechanics with no moving parts subject to wear and tear.
Thus, the compact and robust design is well adapted for harsh
environments in a substation. The visualization display unit
associated with COM600S or COM600F can be based on a
COTF industrial-grade touch panel.
Therefore, the entire cPMS load-shedding cluster can be
mounted in the medium-voltage switchgear.
This ensures that the load-shedding power management
system uses the same infrastructure as the medium-voltage
switchgear and protection and control system.
