Choose the buses for which you would like to draw QV curves – Toggle the QV Selected Column to YES for the buses you would like to analyze – You may also enter the per unit voltage ranges for which you would like to draw the QV curve (or just leave them blank and a global setting on the Options tab will be used).Open the QV Curves dialog by choosing Add Ons ribbon tab QV Curves.Add only one contingency which has a single action: – Open Branch 2 (TWO) – 5 (FIVE) CKT 1.Go to Tools ribbon tab Contingency Analysis to define the contingencies which will be used in the QV study.Modify your case by opening the line from Bus 5 to Bus 7.

To maintain stability expect voltage (V) to increase as vars (Q) are increased. – Negative sensitivity indicates an unstable system. Smaller positive sensitivity indicates more stable system. V-Q sensitivity indicative of stable/unstable operation – Positive sensitivity indicates a stable system.The V-Q sensitivity of a bus is the slope of its QV curve at the given operating point.

V-Q sensitivities can be calculated much more quickly than a full QV curve.V-Q sensitivities are calculated from a solved power flow solution at a particular operating point.V-Q sensitivities can provide a more systemwide view of stability.Unless known problems exist, the selection of buses could exclude problem buses.PV and QV curves require selection of specific buses for analysis.
