SgurrEnergy shows it’s ahead of the curve following release of new standard

SgurrEnergy, part of Wood Group’s clean energy business, has shown it is ahead of the curve following the publication of a new wind turbine standard from the International Electrotechnical Commission, the 2nd edition of IEC 61400-12-1.

The leading renewable energy and grid integration consultancy’s Power Performance Testing (PPT) services, which deliver wind turbine power curve tests, are fully compliant with the latest edition of the standard.

The IEC is the international standards and conformity assessment body for all fields of electrotechnology. The latest edition of its wind turbine power performance assessment standard, IEC 61400-12-1:2017, includes the technical basis for the acceptance of lidar measurements in wind turbine power performance testing.

Power curve tests support the delivery of successful wind power projects. Actual power curves can be compared to the warranted power curve provided by the wind turbine manufacturer. This ensures the requirements of the turbine supply agreement are fulfilled. The manufacturer can then correct any sources of underperformance if these are discovered as a consequence of the test. PPT also de-risks wind power projects with evidence of satisfactory performance in line with pre-construction production estimates and a baseline for ongoing monitoring.

SgurrEnergy’s senior scientist, Prof Peter Clive, who was a member of the committee which wrote the latest edition of the standard, said: “It is encouraging that SgurrEnergy’s PPT services are recognised as being fully compliant.

“This confirms our significant track record undertaking power curve tests on a wide range of wind turbine models and ensures that our tests are accepted by wind turbine manufacturers and the finance community.

“We strive to be at the forefront of technology, so it’s also great to see that many of the techniques supported by the latest edition were in fact pioneered by SgurrEnergy. For example, the t-piece method, which uses scanning lidar installed on the transition piece of an offshore wind turbine, is the only IEC compliant approach offshore that does not require the installation of an additional fixed platform.

“This is made possible by the inclusion of guidance on the use of lidar in the new edition. The cost of tests is massively reduced as a result. The role of the tests can now be extended to include operations and maintenance and investigating the influence of complex wind conditions on power performance.

“The capabilities of lidar are transforming the way we do wind power.”
