1 Scope
Wave Energy Converters (WEC) need to be designed to operate efficiently at different
locations. Systematic methods should be used to evaluate the power performance of
a WEC at a second location (hereinafter Location 2) based on power performance assessment
at a first location (hereinafter Location 1). The degree of similarity of the measured
WEC (WEC 1) and the metocean conditions at Location 1 to the secondary WEC (WEC 2)
at Location 2 determine the methodology and the applicability of this technical specification.
This part of IEC 62600, which is a Technical Specification, describes the required methods and the required
conditions to determine the power performance of the WEC 2 in Location 2, possibly
at a different scale and with configuration changes to accommodate the new site conditions,
in all cases based on measured power performance of WEC 1 in Location 1. This technical
specification allows for assessment at Location 1 or Location 2 based on limited/incomplete
data material, as long as this is accompanied by a validated numerical model or physical
model and assessment of the uncertainty involved. Another key element is transparency
in the assessment.
This technical specification includes:
-
a) Specification of data requirements needed from the original measurements at Location 1 including an assessment of the uncertainty involved (if based on limited/incomplete data material) in addition to those specified in IEC TS 62600‑100 and IEC TS 62600‑101.
-
b) Limitation on the changes that are allowed to the WEC and the specification of the location.
-
c) Wave data required at Location 2, as a minimum the requirements found in IEC TS 62600‑101.
-
d) Development of the power matrix at Location 2.
-
e) Validation of the power matrix at Location 2.
-
f) Assessment of uncertainties in the derived performance parameters at Location 2.
-
g) Requirements for the allowable power performance transfer by geometric, kinematic and dynamic similarity.
-
h) Requirements for the allowable incorporation of additional empirical model data.
-
i) Requirements for the allowable incorporation of additional numerical model data.
The technical specification does not cover the following items:
-
j) The original data measurement at Location 1 (see IEC TS 62600‑100).
-
k) Environmental concerns.
-
l) Operation and maintenance.
