SAIFI / SAIDI Report
Summary

The System Average Interruption Frequency Index (SAIFI) / System Average Interruption Duration Index (SAIDI) report is use to measure the Distribution System Reliability.

The report includes the following:

  • average number of interruptions

  • average outage

  • reliability factors

  • power availability over the reporting period.

SAIFI / SAIDI reports are generated based on the data from ION meters selected in the report configuration.

Supported devices are ION 7300, ION 7330, ION 7350, ION 7500, ION 7600, ION 7700, PM8000, ION 8400, ION 8500, ION 9000, ION 8300, ION 7550, ION 7650, ION 8600, ION 8800, ION 8650, ION 8600C, ION 8650C, ION 8800C, ION 7400, ION 7400 Essential, PM8000 Essential.

RECOMMENDATION: Select the meters at the feeder level and not at the sub-feeder level.

Details

SAIFI is the average number of sustained interruptions per consumer per year / average number of times, in a system outage during a period. It is the ratio of the annual number of interruptions to the number of consumers.

SAIFI = Number of consumers at feeder level * Number of interruptions /(Total number of consumers including all feeders)

SAIDI is the average duration of interruptions per consumer per year / month / day. It is the ratio of the aggregate annual duration of interruptions (sustained) to the total number of consumers served.

SAIDI = (Number of consumers * Total Sustained Interruption Time)

Prerequisites

A configuration settings must be done in the PME web Settings > System > SAIFI SAIDI Configuration page for:

  • Sustained Interruption - Set the outage duration between 1 - 59 minutes only.

  • Adding / editing / removing the ION devices and adding the number of consumers:

    • Select the ION devices for which you want to have the report.

    • To add / edit a device, select the device and you will get a new window. Enter the Name and Number of consumers. select OK, then select Save Configuration to save the data.

    • To remove a device, unselect the device. select OK, then select Save Configuration to save the data.

The devices added in this configuration file are listed in the SAIFI / SAIDI report sources.

For example:

Report inputs

Type a title for the report in the text box.

The Source Selector dialog provides options to show Devices.

Use the Devices option to select the devices you want to include in the report.

From the Grouping list, select the way in which you want to display the sources (for example by device type or by group name). select Select All or Select None in the top-right corner to select or clear all the check boxes.

After selecting the devices, select OK.

Use this input to select the time-frame for the data you want to view in the report.

Select the reporting period from the drop-down list. The time-frame options in the time-frame drop-down are relative to the date the report is run. Use a relative date option for reports that you want to generate on a regularly scheduled basis. To run a report that starts and ends in the past, select the fixed date option. Type a start and end date in the date boxes or select the arrows beside the dates to display a pop-up calendar and select a date. Type a time in the time boxes or select the up and down arrows beside the time to adjust the hours or minutes up or down.

Select whether you want to view timestamps in either Server Local Time or UTC (Universal Coordinated Time).

Example:

Item Details
Total time Number of days * 24
Total Available time Total time - (momentary + sustained) interruption time
% of availability Total Available time / Total time
SAIFI (Number of consumers at feeder level * Number of interruptions) /(Total number of consumers including all feeders)
SAIDI (Number of consumers * Total Sustained Interruption Time)
Data Notification It provides you the details of the notification.
