Viewing Data in the SCADA Summary
Viewing All SCADA Data
To open the SCADA Summary for all measurements, select SCADA Summary... from the Web Workspace Tools menu.
Viewing SCADA Data for a Selected Device
To open the SCADA Summary for a specific device, select the device or feeder in the Viewer and launch the Control Tool. Click SCADA Summary... and select one of the options:
• Device...: loads the SCADA Summary with the SCADA measurement data for the selected device.
• Feeder...: loads the SCADA Summary with SCADA measurement data for the selected device's feeder.
• Substation...: loads the SCADA Summary with SCADA measurement data for the selected device's substation.
When the SCADA Summary is launched from the Control Tool, the data source is shown in a bar above the table.
Note: If you select Load All from the SCADA Summary Actions menu or click the X button (
) on the bar above the table, the table will be repopulated with all measurements and the bar will be removed.
) on the bar above the table, the table will be repopulated with all measurements and the bar will be removed. Loading SCADA Summary Data for a Different Device
Once the SCADA Summary has been opened (from the Control Tool), you can view data for a different device by selecting it in the Viewer, and then clicking the Load button in the bar above the data table.
Preventing Measurement Updates
To prevent a SCADA measurement from accepting updates from SCADA, complete the following steps:
1. Select SCADA Summary... from the Web Workspace Tools menu. The SCADA Summary window opens.
2. Select a row in the SCADA Summary table corresponding to the device measurement that you want to prevent from updating.
3. Click the Inhibit button.
Manual Entry and Override of SCADA Measurement Values
Occasionally, you may need to manually enter a status, digital value, or analog value for a SCADA measurement. For example, you may need to enter fault current and fault indicators to trigger Fault Location Analysis (if applicable). See Chapter 20, Fault Location Analysis for more information.
If the value for the selected measurement is a switch status measurement (that is, open/close), you must choose Show Control Tool... from the context menu to manually operate the switch. Otherwise, use the following procedure to enter a value manually:
1. Select SCADA Summary... from the Web Workspace Tools menu. The SCADA Summary window opens.
2. Select the SCADA measurement row in the SCADA Summary list.
3. Click either the Manual Entry or Manual Override button.
Note: Manual Entry allows future SCADA value changes to replace the manually entered value. Manual Override prevents SCADA measurements received by the system from changing the manually entered value. Manual Override can be useful when testing specific devices or RTU communications offline, since the test operations can be prevented from creating outages in Oracle Utilities Network Management System by putting manual overrides on the appropriate status measurements.
If the value for the measurement is a multi-state digital, analog, or any type of measurement other than a switch status measurement (open/close), a dialog box opens, allowing you to enter a value.
Note: Multi-state digitals are not available through the Oracle Utilities Network Management System SCADA ICCP Block 1, 2, and 5 Adapter.
4. Select or enter the value you want to change the measurement to.
5. Click OK.
Note: Clicking Manual Override blocks any new values coming from the SCADA measurement. It does not affect the physical SCADA device, it only blocks the value reported by the SCADA device to Oracle Utilities Network Management System.
Adding and Modifying Comments for SCADA Status Changes
When you change the SCADA state to Inhibit, Manual Override, or Disabled in Power Flow, you can enter comments to record why the state was changed. When you initiate Inhibit or Disable in Power Flow actions, a dialog box will open allowing you to enter a comment; for Manual Override, a Comment field is available below the Value field. The comment text, user, and date and time the comment was entered will be added to the selected device's SCADA Summary row.
Existing comments may be edited by selecting the SCADA Summary row and selecting Edit Comment... from the Actions menu.
Disabling/Enabling Measurements in the Power Flow Solution
If you see anomalies in the SCADA data (for example, due to mapping issues, transducer issues, or temporal issues, and so on) where SCADA values seem potentially unhelpful in allowing FLMService to solve, you can disable the suspected measurements from taking part in the power flow solution by doing the following:
1. Select the suspected measurements in the SCADA Summary.
2. Click the Disable in Power Flow button from the Actions menu or the right-click option menu. The Quality column value will be set to S for the selected measurements.
To re-enable the disabled measurements:
1. Select the disabled measurements from the SCADA Summary tool
2. Click the Enable in Power Flow button from the Actions menu or right-click context menu. The Quality column value will be changed from S to blank for the selected measurements.
Understanding the Change Limits Dialog Box
The change limits dialog box allows you to change the current limit set for a single measurement (for example, from Spring to Summer). The dialog box displays the following fields:
• The Measure displays the selected measurement.
• The Limit Set allows you to select the new limit set from a list of limit sets associated with the group.
Buttons
• OK: Save the change in limit set and close the dialog box.
• Cancel: Cancel the change in limit set and close the dialog box.
Understanding the Override Limits Dialog
The Override Limits dialog allows you to override one or more limit bands associated with the measurements limit set for a temporary period of time. The dialog box displays the following components:
• The Measure field displays the selected measurement.
• The Limit Set field contains the current limit set for the selected measurement.
• The Override Duration contains the duration of the override in hours and minutes.
• The Reason field allows you to enter a reason for overriding the limits.
• The Limit Bands table contains the current limit bands for the measurement. The table contains the following information for each limit band:
• The name of the band.
• The value of the band.
• The limit ref displays the reference measurement for this limit band if this band is an implicit or explicit reference.
• The reference type indicates whether this is a soft or hard reference.
• The description holds the description of the band.
See Understanding Limits for details on dynamic limit references and their types.
By default, the Limit Value will display a different background color based on the following events:
• dark red: The bands value is overridden.
• light red: The band is a reference to another measurement whose SCADA quality is bad.
• light green: The band is a reference to another measurement whose SCADA quality is good.
To override a band, enter a new value in the Limit Value column.
Buttons
• The Remove Override button will remove a previously applied override and return the limits back to their default values.
• The Apply Override button will apply the current overrides to the measurement for the specified duration.
• The Cancel button will close the dialog box with removing or applying any overrides.
SCADA Measurements Trend Graph
The SCADA Trend Graph tool displays historic or real-time trend lines for up to 9 SCADA measurements as long as there are no more than two distinct units of measure (for example, Amps and kW) between them.
The tool contains two main parts: the graph that displays trend lines and the Trends collapsible panel that contains the list of saved SCADA Trend Graph configurations.
