Scope

NB/T 10387-2020 is the English-translated version of 海上风电场风能资源小尺度数值模拟技术规程.

NB/T 10387-2020 is the Chinese energy industry specification for small-scale numerical simulation of wind energy resources at offshore wind farm sites.

It lists the input data to gather, such as on-site wind measurements, topographic maps at scales from 1:2 000 to 1:10 000, turbine power curves, neighbouring wind farms and mesoscale data, and sets rules for choosing linear or nonlinear fluid dynamics models, wake models, atmospheric stability, turbulence models and the number of calculation sectors.

Nonlinear models are required where land, islands, other wind farms or structures affect the flow. Further chapters cover coupling with mesoscale data, the results to report, verification against measurements and uncertainty analysis. Issued on 23 October 2020, it has applied since 1 February 2021.
