In our example, the following phase and zero-sequence compensation equations would be used:
For Winding 1:
;
;
(EQ 5.16)
For Winding 2:
;
;
(EQ 5.17)
g) MAGNITUDE, PHASE ANGLE, AND ZERO SEQUENCE COMPENSATION
Complete magnitude, phase angle, and zero sequence compensation is as follows:
(EQ 5.18)
(EQ 5.19)
(EQ 5.20)
where:
,
, and
= magnitude, phase and zero sequence compensated winding
w
phase currents
= magnitude compensation factor for winding
w
(see previous sections)
,
, and
= phase and zero sequence compensated winding
w
phase currents (see earlier)
