Description / Abstract:
The scope of this TSS is limited to the testing of PMU
electrical performance. As of this revision of the TSS, the
standard for PMU performance is IEEE Std C37.118.1™-2011, IEEE
Standard for Synchrophasor Measurements for Power Systems as
modified by IEEE Std C37.118.1a™-2014.1
This TSS will be revised as the standard for PMU performance is
revised. Users are encouraged to check for the latest revision of
this document.
Purpose
This test suite specification (TSS) provides organizations that
are testing phasor measurement unit (PMU) performance with a suite
of unambiguous test plans in accordance with the Smart Grid
Interoperability Panel (SGIP) Interoperability Process Reference
Manual (IPRM).
This TSS further provides requirements for equipment used for
the testing of PMUs, requirements for the measurements made by PMU
test equipment, and requirements for the reporting of PMU
measurements.
Test plans and requirements in this TSS are more specific than
requirements of the standard for PMU performance. The standard
specifies the test signals to be input to a PMU under test and the
performance limits that must be met by the PMU, but neither
specifies the test procedure to be used nor the specific
calculations made to determine PMU performance. Without specific
test procedures and calculations, tests that are implemented by
different test designers may yield different results.
Furthermore, some ambiguities in the standard are identified and
this TSS sets requirements based on a single interpretation of the
ambiguous clauses. In accordance with the SGIP IPRM, the authors of
this document will work closely with the standard setting
organizations to resolve the ambiguities in future revisions of the
standard. This TSS may be revised thereafter to reflect the
standard's revision once it is published.
PMU testing organizations that participate in The Institute of
Electrical and Electronics Engineers Conformance Assessment Program
(ICAP) PMU Conformance Assessment Program must comply with the test
plans and requirements in this document. Conformance with this TSS
is assessed as part of the ICAP program.
