CEI EN 61975

ENGLISH

This International Standard applies to system tests for
high-voltage direct current (HVDC) installations which consist of a
sending terminal and a receiving terminal, each connected to an
a.c. system.

The tests specified in this standard are based on bidirectional
and bipolar high-voltage direct current (HVDC) installations which
consist of a sending terminal and a receiving terminal, each
connected to an a.c. system. The test requirements and acceptance
criteria should be agreed for back-to-back installations, while
multi-terminal systems and voltage sourced converters are not
included in this standard. For monopolar HVDC installations, the
standard applies except for bipolar tests.

For the special functions or performances that are claimed by
specific projects, some extra test items not included in this
standard should be added according to the technical specification
requirements.

This standard only serves as a guideline to system tests for
high-voltage direct current (HVDC) installations.The standard gives
potential users guidance, regarding how to plan commissioning
activities. The tests described in the guide may not be applicable
to all projects, but represent a range of possible tests which
should be considered.

Therefore, it is preferable that the project organization
establishes the individual test program based on this standard and
in advance assigns responsibilities for various tasks/tests between
involved organisations (e.g. user, supplier, manufacturer,
operator, purchaser etc.) for each specific project.
