PML630/Compact Load-Shedding Solution
Product version: 1.2.1
However, the total performance of end-to-end performance of
the cPMS load-shedding solution configuration A depends on
various factors.
• HW binary input and output activation times in feeder
protection relays
• GOOSE transmission times between the protection relays
(maximum ~10 ms for Relion 615, 620, and 630 series)
• Application function cycle times in the feeder protection
relays
• PML630 device load-shedding logic execution time
• External trip contact operation time
The end-to-end performance of the configuration A is achieved
[1]
within 60 ms . In case of Configuration B, the load-shedding
action in power network area 2 due to a contingency in power
network area 1 is achieved within 90 ms
circuit breaker opening time, the overall performance times can

17. Redundancy

The 630 series family does not support communication or
device-level redundancy. To adapt the PML630 to work in a
redundant communication network with other redundant
devices such as 615 and 620 series, an external redundancy
box is needed. With such unit, PML630 can be used in a
network supporting High Availability Seamless Redundancy
(HSR) or Parallel Redundancy Protocol (PRP).
A 100% redundant and independent PML630 device with
identical configuration to the main PML630 device can work
together to achieve load-shedding device-level redundancy.
