VAR Tab
Figure 5-13 illustrates the settings, sensing values, and alarm signal indicators of the VAR tab. Each
setting of the VAR tab is described in the following paragraphs.
Reactive Power Step Response - VAR Setpoint (%) (Nominal). This read-only field indicates the var
setpoint. (The var setpoint is set by using the Setpoint tab of the Setting Adjustments screen.) The value
displayed in the "VAR Setpoint" field is selected by clicking the adjacent button. Clicking this button sends
the var setpoint value to the DECS-100 and changes the color of the pushbutton from gray to red.
Reactive Power Step Response - Increment of VAR Setpoint (%). This field indicates the increase that
occurs to the FCR setpoint when the corresponding Increment button is clicked. The "Increase VAR
Setpoint =" field is used to set and indicate the percentage that the var setpoint is increased to when the
Increment button is clicked. Any setpoint value (expressed as a percent of nominal) within range or higher
than the existing setpoint value can be typed into the "Increase VAR Setpoint =" field. The var setpoint
changes to the new value when the adjacent button is clicked. Clicking this button sends the var setpoint
value to the DECS-100 and changes the color of the pushbutton from gray to red.
Figure 5-13. Analysis Screen, VAR Tab
Reactive Power Step Response - Decrement of VAR Setpoint (%). This field indicates the decrease that
occurs to the FCR setpoint when the corresponding Decrement button is clicked. The "Decrease VAR
Setpoint =" field is used to set and indicate the percentage that the var setpoint is decreased to when the
Decrement button is clicked. Any setpoint value (expressed as a percent of nominal) within range or lower
than the existing setpoint value can be typed into the "Decrease VAR Setpoint =" field. The var setpoint
changes to the new value when the adjacent button is clicked. Clicking this button sends the var setpoint
value to the DECS-100 and changes the color of the pushbutton from gray to red.
Reactive Power Step Response - Meter Value. These fields and the dial pointer indicate the value of the
selected var setpoint. When the var setpoint is changed by clicking the increment, decrement, or setpoint
button, the meter value fields and dial pointer indicate the setpoint value. A new var setpoint, expressed
as a kvar value or a percentage of nominal, can be typed directly into either Meter Value field or selected
by dragging the dial pointer to the desired value. The new value is sent to the DECS-100 by clicking the
Send button.
Reactive Power Step Response - Current Setpoint (%). The active var setpoint (adjusted by using any of
the previously mentioned methods) is displayed in this field. To return the var setpoint to the nominal
setting, the button adjacent to the "VAR Setpoint (%) (Nominal)" field should be clicked. If the VAR tab is
left to view other tabs or screens without returning the VAR setpoint to nominal, a var setpoint dialog box
appears. Clicking the Yes button returns the var setpoint to nominal. Clicking No maintains the var
setpoint at the current value.
