Detailed CGCM Unit Tag Descriptions Appendix E
Line-drop Compensation Inputs to the CGCM Unit
• LineDropComp - This tag configures the amount of voltage droop that is
experienced during paralleling generator applications.
Under-excitation Limit Inputs to the CGCM Unit
• UEL_En - Setting this tag enables the Under-excitation Limiting
function.
• UEL_Kg - This tag lets you adjust the proportional gain of the
Under-excitation limiter. It also determines the response of the limiter to
an Under-excitation event. Increasing this term increases the speed of the
response of the limiter.
• UEL_Ki - This tag lets you adjust coarse loop gain and overall gain of the
Under-excitation limiter. This tag determines the characteristic of the
dynamic response to an Under-excitation event.
• UEL_Curve_W_Pt1 – This tag is used as the Watt coordinate in the first
Watt, VAR coordinate pair, that, in combination with four other Watt,
VAR coordinate pairs, lets you enter an Under-excitation Limiting curve.
• UEL_Curve_W_Pt2 – This tag is used as the Watt coordinate in the
second Watt, VAR coordinate pair, that, in combination with four other
Watt, VAR coordinate pairs, lets you enter an Under-excitation Limiting
curve.
• UEL_Curve_W_Pt3 - This tag is used as the Watt coordinate in the third
Watt, VAR coordinate pair, that, in combination with four other Watt,
VAR coordinate pairs, lets you enter an Under-excitation Limiting curve.
• UEL_Curve_W_Pt4 - This tag is used as the Watt coordinate in the
fourth Watt, VAR coordinate pair, that, in combination with four other
Watt, VAR coordinate pairs, lets you enter an Under-excitation Limiting
curve.
• UEL_Curve_W_Pt5 - This tag is used as the Watt coordinate in the fifth
Watt, VAR coordinate pair, that, in combination with four other Watt,
VAR coordinate pairs, lets you enter an Under-excitation Limiting curve.
• UEL_Curve_VAR_Pt1 - This tag is used as the VAR coordinate in the
first Watt, VAR coordinate pair, that, in combination with four other
Watt, VAR coordinate pairs, lets you enter an Under-excitation Limiting
curve.
• UEL_Curve_VAR_Pt2 - This tag is used as the VAR coordinate in the
second Watt, VAR coordinate pair, that, in combination with four other
Watt, VAR coordinate pairs, lets you enter an Under-excitation Limiting
curve.
• UEL_Curve_VAR_Pt3 - This tag is used as the VAR coordinate in the
third Watt, VAR coordinate pair, that, in combination with four other
Watt, VAR coordinate pairs, lets you enter an Under-excitation Limiting
curve.
