PV/QV Curves Results: Track Limits
The Track Limits sub-tab is found on the PV Results tab of the PV Curves dialog or the QV Results tab
of the QV Curves dialog. The results displayed are similar for both the PV and QV analysis. This page
provides access to the results of tracking devices at limits which are determined in the same manner
for both the PV and QV analysis.
The page is divided into several additional sub-tabs for the different types of devices that can be
tracked. Tables on each tab are similar in that they list all of the devices of that type that were
tracked. For PV analysis, each column of the table is the transfer amount at which the device limits
were checked. For PV analysis, device limits are only checked for base case conditions (i.e. no
contingencies are applied). For QV analysis, each column of the table is the per-unit voltage set-point
for the study bus during the scenario in which the limits were checked. The results show where each
element was located relative to its min/max limits during each step of the analysis using the indicators
of Within Limits, Within Range, At Max, and At Min. To simplify the display and exclude those elements
that were always within their limits during all steps of the process, check the box Filter out devices
that never hit or backoff a limit during the PV run.
