PNW 88-908 ED1: Standard file format for sharing power curve information

Scope

The proposed standard will establish minimum reporting requirements for OEMs to communicate wind turbine power curve information. The design basis of the turbine associated with a particular power curve will always be tracked, to ensure that site suitability evaluations can be conducted in parallel with energy analysis. A key objective of the proposed standard is to define a machine-readable file format that will benefit all stakeholders.

Purpose

Currently, power curve information is communicated in many different ways with varying degrees of background information (incomplete or missing critical details). Often the necessary information is spread across multiple documents requiring human interaction. Sometimes, the core power curve information is in a locked format that requires manual transcription which can lead to errors. Furthermore, power curves are becoming more complex with different operating modes, ranges of air density and turbulence intensity, thermal derates, thrust settings, and more. The growing complexity makes data management quite challenging. Owners and their agents across the globe would all benefit from improvements in how power curve related data is communicated; errors would be reduced, duplication of post-processing by different entities avoided, and analysis accelerated
