Negative reactance control (alternative method to circulating current compensation)
The relay should be commissioned with the settings calculated for the application.
Reverse reactance control is an alternative method to circulating current compensation.
This test verifies the operation (i.e. reversal of Vx vector) when used with line drop
compensation. It also checks the operation of the load angle compensation on the V
R
vector by determining regulation with various load angle settings (ANGLE).
[Before making the following changes note the settings and system data links for: SD1
link to 0, dead band setting dVs, intertap delay (tINTER), system voltage input setting
(Vs), circulating compensation voltage setting (Vc), resistive line drop compensation
setting (Vr), reactive line drop compensation setting (Vx), load current setting (
I
L)].
Set the:
-
SD1 link to 0,
-
dead band setting dVs to 1%
-
intertap delay (tINTER) to 0 seconds,
-
system voltage input setting (Vs) to 100V
-
circulating compensation voltage setting (Vc) to 0V,
-
resistive line drop compensation setting (Vr) to 10V,
-
reactive line drop compensation setting (Vx) to 10V,
-
load angle (ANGLE) of 40 degrees
-
load current setting (
I
L) to 1
I
n].
Apply 1A load current to terminals 27 & 28.
Apply 103.28V, adjust the phase angle until the current leads by 40 degrees.
Check the relay regulates within this applied voltage ±1%. Check that the TAP is initiated
outside the regulated voltage by increasing the input voltage and by monitoring the
‘CONTROL’ LED. The ‘CONTROL’ LED should illuminate for a period set by tPULSE
when input voltage is increased to outside the regulated voltage.
[Restore the following settings and system data links:
-
SD1 link to 0,
-
dead band setting dVs,
-
intertap delay (tINTER),
-
system voltage input setting (Vs),
-
circulating compensation voltage setting (Vc),
-
resistive line drop compensation setting (Vr),
-
reactive line drop compensation setting (Vx),
-
load angle (ANGLE),
