This paper reports the findings in a national
survey conducted in 2008/2009 on the quality of supply. The
respondents are from distribution system operators (DSOs) and
from the Norwegian Transmission system operator (TSO). The
survey was implemented as a web based survey and covered all
quality of supply phenomena defined in EN 50160 [1]. In
addition some EMC issues also were included. The objective of
the survey was to investigate which phenomena are the most
important and what the utilities’ needs to improve quality of
supply management.
The phenomena causing most problems in Norway are:
- Supply voltage variations
- Short duration supply interruptions
- Voltage dips
These phenomena are of highly ranked both by the Norwegian
TSO and the DSOs responding to the survey.
The most important need for quality of supply improvement
according to the DSOs is to get advice concerning
measurements and measurement equipment:
The TSO sees basic technology transfer, national databases,
advice concerning measurements/ measurement equipment and
standardisation as important issues in general, but the needs are
different for different phenomena.
