EN 50160 Conformance Tracking
Introduction
EN 50160-2010 is a European standard that defines, describes, and specifies
characteristics of voltage that is supplied in public power supply networks. The
standard specifies limits on various attributes of the supply voltage, such as
magnitude, frequency, and waveform quality, during normal operation. The
PowerMonitorâ„¢ 5000 M8 model measures and stores data that track
conformance to the requirements defined in the standard, for low-voltage
(1000V or less) and medium-voltage (1…36 kV) systems.
EN 50160 conformance tracking data is measured according to requirements
detailed in the accompanying standard EN 61000-4-30, further described in
Appendix I
.
The power monitor tracks the following voltage supply parameters over defined
intervals and reports each as described. Invalid intervals, in which a voltage
interruption occurs, are flagged and excluded from the conformance results.
Compliance criteria can differ depending on whether the system is low or
medium voltage and whether the system has a synchronous connection to an
interconnected system (the grid) or not (islanded). The compliance record lists
each parameter and records the number of valid intervals where the parameter
measured exceeded the specified compliance criteria.
Setup
Basic metering setup is required. The power monitor selects EN 50160
conformance criteria that are based on the value of the
Nominal_System_LL_Voltage parameter in the Configuration.Metering.Basic
table.
The Configuration.PowerQuality
table includes another parameter that affects
the selection of conformance criteria.
The PowerFrequency_Synchronization tag indicates the synchronization status
of the metering system. The choices include the following:
• 0 = Synchronous connection to an interconnected system default
• 1 = Not synchronous to an interconnected system (islanded)
