Energy data monitoring
Permanently monitoring energy data is one of the most important tasks. Are all system components working flawlessly? Are all consumption values within the projected range? Here, you will learn how these tasks are accomplished invisual energy 4:
To determine when the data was last refreshed, change to the subscribed OBIS codes view via the meter point.
With a status report, you can see at a glance whether all period values of a time range are available. As the status of each individual value is displayed, you can recognize disturbed values, substitute values or missing values. The easiest way to access the status report is via the toolbar of the meter point list.
Setting up the automatic energy data monitoring function
In visual energy 4, you can define expected values for each meter point. This way, consumption can be permanently monitored using minimum and maximum values. Limits can be defined as absolute values (units of consumption) or relative (in %) to the previous period.
The following tasks are possible:
Consumption recording function control
It is a lengthy process until the measured values reach the central energy database over the measurement system, field bus and network. Plenty of components have to work together flawlessly to make sure that the values for the entire time range are available in the end. KBR has invested a lot to optimize the functional reliability of the individual systems. Nevertheless, some problems cannot be ruled out completely. Just think of meters being changed, forgotten transformer bridges or modified IT systems. Energy data monitoring can be used to validate measured values as a final check.
Checking extreme values
In most scenarios, the measured values are monitored at the measuring and control devices. These can be load management systems or multimeters. However, there are also situations in which it makes more sense to check the measured values only after the database has been updated. Large-volume water withdrawals, for example in case a pipe burst on the premises is not detected, are hard to monitor with a measuring device, as the "pipe burst" signal can only be recognized if the consumption is monitored over an extended time range.
In summary: Energy data monitoring is recommended whenever continuous monitoring does not make sense and, for example, hourly or daily consumption value monitoring is more reasonable.
Select the desired meter point from the meter point list and click on the OBIS button:
Switch to the 'Validation' tab. Here you can set up a monitoring process for each OBIS value. To do so, select one of the existing measuring parameters and click on the button to set up the actual monitoring function.
1, 4, 24, 48 or 96 periods are possible time ranges. Furthermore, measured values can be monitored absolutely or relatively with reference to the previous time range. Please note that the values are monitored continuously.
Example for monitoring 4 periods (1h, with a period duration of 15 minutes)
00:15 - 01:15
00:30 - 01:30
00:45 - 01:45
01:00 - 02:00 usw.
Provided that the consumption monitoring service is activated, the set limit values are monitored as long as the service is executed. In case of a violation, a report is created. The report is saved as a PDF file in the report folder and, if the mail system has been set up correctly, is sent to you.
