SENSITIVE DIRECTIONAL POWER
DIRECTIONAL POWER 1(2)
The sensitive directional power element responds to three-phase directional power and is designed for reverse power and
low forward power applications for synchronous machines or interconnections involving co-generation. The relay measures
the three-phase power from either full set of wye-connected VTs or full-set of delta-connected VTs. In the latter case, the
two-wattmeter method is used. Refer to the
UR-series metering conventions
section in chapter 6 for details regarding the
active and reactive powers used by the sensitive directional power element.
The element has an adjustable characteristic angle and minimum operating power as shown in the
Directional power char-
acteristic
diagram. The element responds to the following condition:
(EQ 5.19)
where:
P
and
Q
are active and reactive powers as measured per the UR-series metering convention,
θ
is a sum of the element characteristic (
DIR POWER 1 RCA
) and calibration (
DIR POWER 1 CALIBRATION
) angles, and
SMIN
is the minimum operating power
The operating quantity is displayed in the
