2.6.2 Setting Notes
The power swing supplement is only active if it has been set to Power Swing =
Enabled (address 120) during the configuration. For Power Swing no other param-
eters have to be set.
The four possible programs may be set in address 2002 P/S Op. mode, as de-
scribed in Section 2.6: All zones block, Z1/Z1B block, Z2 to Z5 block or
Z1,Z1B,Z2 block.
Additionally the tripping function for unstable oscillations (out-of-step condition, loss of
system synchronism) can be set with parameter PowerSwing trip (address 2006),
which should be set to YES if required (presetting is NO). In the event of power swing
tripping
it is recommended to set P/S Op. mode = All zones block for the power
swing blocking
, to avoid premature tripping by the distance protection.
The tripping delay after power swing blocking can be set in address 2007 Trip
DELAY P/S.
