Using the Feeder Load Management Window
The Feeder Load Management window provides detailed information about feeder loads, device violations and warnings, tie points capacity, and regulation devices. It supports real-time and study mode.
This section includes the following topics:
Accessing the Feeder Load Management Window
You can open the Feeder Load Management window from the Viewer or from the Feeder Load Summary window.
From a Viewer
To open the Feeder Load Management window from a Viewer, select Feeder Load Management... from the Viewer's Tools menu or click the Feeder Load Management button () on the Viewer toolbar.
The Feeder Load Management mode is defined by the Viewer's mode.
Note: Feeder Load Management can be disabled for some of the feeders using the Configuration Assistant's Feeder Management tab (see Using the Feeder Management Tab for details).
From the Feeder Load Summary Window
From the Feeder Load Summary window, you can open the Feeder Load Management window for a single feeder or for multiple feeders.
• To open the Feeder Load Management window for a single feeder, double-click the corresponding row in the Feeder Load Summary table or right-click the row and select Feeder Load Mgmt Tool or Feeder Load Mgmt Tool 2 from the context menu.
• To open the window for multiple feeders, select the corresponding rows in the Feeder Load Summary Table and click the Feeder Load Management button ().

• Voltage Regulation: Indicates if Voltage Regulation is present. Administration and Full Operations users can change this value using the Regulation Device Parameters dialog box to either on or off for devices that are voltage regulated.
• Voltage Setpoint: The voltage regulation set point. Administration and Full Operations users can change this value using the Regulation Device Parameters dialog box when Voltage Regulation is present on the device and turned on.
• Min PF - Leading: Minimum Leading Power Factor
• Min PF - Lagging: Minimum Lagging Power Factor
• Target kW: Real Power Target (kW)
• Target kVAr: Real Power Target (kVAr)
• TTL Expiration: the time to live expiration of the generator. Administration and Full Operations users can reset this value using the Regulation Device Parameters dialog box if the device is affected by TTL. This value can be driven from a SCADA signal.
• Status: whether the unit is On or Off; can be driven from a SCADA signal. Like, kW and kVAr, the status can be modified using the Regulation Device Parameters dialog box.
• Charge Mode: whether the unit is Charging, Discharging, or Idling; can be driven from a SCADA signal.
• Wind Speed (mph): the wind speed of the DER zone.
Note: For wind DERs, it will show the speed of its zone; for non-wind DERs, it will show N/A.
• Cloud Cover: The cloud cover of the DER zone.
Note: For solar DERs, it will show the cloud cover data of its zone; for non-solar DERs, it will show N/A.
Load Details Tab
The Load Details tab displays all sources electrically connected to the feeder selected on the Feeder Load Overview Tab. The feeder head will typically characterize each feeder and 3 to 5 closed sectionalizing devices. Some of these sectionalizing devices will have measurements and may be supervisory control points.
Note: This pane is available only when a present load row is selected in the Feeder Load Overview table.
Click the power flow results button () to toggle on/off a filter that displays only SCADA readings. When toggled on, only SCADA devices are displayed in the Load Details table. This view displays the device readings and data quality.
The Load Details includes the Feeder Load Details table and a toolbar. In study mode, the toolbar includes a refresh button and a device field that allows you to add a particular device to the Load Details screen and the Devices drop-down list on the FLM Graphical View tab. Click the Refresh button to trigger a new solution with this device. The Load Details table includes the following columns:
• Device: The name of the device.
• Amps A: Solved Phase A Current
• Amps B: Solved Phase B Current
• Amps C: Solved Phase C Current
• Amps N: Solved Neutral Current
• kW A: Solved Phase A Active Power
• kW B: Solved Phase B Active Power
• kW C: Solved Phase C Active Power
• kVAr A: Solved Phase A Reactive Power
• kVAr B: Solved Phase B Reactive Power
• kVAr C: Solved Phase C Reactive Power
• kVA A: Solved Phase A Apparent Power
• kVA B: Solved Phase B Apparent Power
• kVA C: Solved Phase C Apparent Power
• kV A: Solved Phase A Voltage
• kV B: Solved Phase B Voltage
• kV C: Solved Phase C Voltage
• Has SCADA: Flag indicating whether it is a SCADA device (hidden by default).
• Quality A: Phase A quality code. Displayed when the power flow results button has been toggled on.
• Quality B: Phase B quality code. Displayed when the power flow results button has been toggled on.
• Quality C: Phase C quality code. Displayed when the power flow results button has been toggled on.
Quality codes can be one of the following:
• Filtered: Measurement point has been filtered (removed) from consideration in the load flow engine.
• Valid: All data associated with this measurement seems to be valid.
• Invalid: Measurement point has been flagged as invalid by data gathering system (for example, SCADA).
• Estimated: Value has been estimated by state estimation.
• Suspect: A component of a field measurement that contributes to this value is missing, out of range, or otherwise suspect.
• Load: There is an irreconcilable mismatch between the load reported by field measurements and the load flow model. For example, a section with no generation has negative load.
• Profile: There is a significant difference between the expected power factors from the model and that reported by field measurements.
• Factor A (kW/kVAr): The phase A kW/kVAr scaling factors that are applied to scale the load. Displayed when the power flow results button has been toggled off and SCADA values are displayed.
• Factor B (kW/kVAr): The phase B kW/kVAr scaling factors that are applied to scale the load. Displayed when the power flow results button has been toggled off and SCADA values are displayed.
• Factor C (kW/kVAr): The phase C kW/kVAr scaling factors that are applied to scale the load. Displayed when the power flow results button has been toggled off and SCADA values are displayed.
Voltage Profile Graph Tab
The Voltage Profile Graph tab displays a graph of voltage load (p.u.) versus distance from the feeder head for a feeder selected in the Feeder Load Overview Tab. The graph also displays the upper and lower ANSI Range A violation limits (1.05 and 0.95 p.u., respectively).
Note: This pane is available only when a present load row is selected in the Feeder Load Overview table.
Supply points are represented by a symbol in their phase color. You can choose to view all phases (default) or individual phases by selecting the phase from the drop-down list.
Drop-Down List Options
• All: displays all phases plotted in their respective colors.
• Phase A: Phase A loads are displayed (red dots).
• Phase B: Phase B loads are displayed (yellow triangles).
• Phase C: Phase C loads are displayed (blue squares).
Note: Bellwether loads are displayed in pink.
