Wind power plant wind measurement equipment

What is a wind measurement program?

This stage applies to wind measurement programs to characterize the wind resource in a defined area or set of areas where wind power development is being considered. The most common objectives of this scale of wind measurement are to: Screen for potential wind turbine installation sites.

What are the instrumentation components of a wind resource monitoring station?

This chapter describes the instrumentation components of a wind resource monitoring station. It provides details on a station's major components (sensors, tower, and data logger) as well as the peripheral parts such as power supplies, wiring, earth grounding, data storage devices, software, and communication systems.

What are wind measurement guidelines?

These guidelines, which are detailed and highly technical, emphasize the tasks of selecting, installing, and operating wind measurement equipment, as well as collecting and analyzing the associated data, once one or more measurement sites are located.

How accurate is wind speed measurement?

Users of wind speed measurement data for the assessment of available wind energy often request a rather high accuracy in the order of 1%, because wind energy depends on the third power of the wind speed (51.1). A 1%-error in wind speed thus means up to 3% error in wind energy.

Why do wind monitoring programs need a measurement plan?

Common to all monitoring programs is the need for a measurement plan. Its purpose is to ensure that all facets of the wind monitoring program combine to provide the data you need to meet your wind energy program objectives.

How high should a wind turbine be measured?

Multiple measurement heights are encouraged for determining a site’s wind shear characteristics, conducting turbine performance simulations at several turbine hub heights, and for backup. Heights typical of recent NREL-affiliated wind measurement programs are 40 m, 25 m, and 10 m.
