From the earliest days of wind energy, measurements have played a crucial role. Starting with the siting of wind farms but reaching to advanced power performance studies. No wonder, because the “fuel” available is the single most important factor in the economics of a wind farm.
For a long time – and in many cases still today – the cup anemometer has reigned supreme, for good reasons, since it is relatively accurate and cheap. However, with the rapid increase of the hub height, and with that height of the tip of the rotor it is becoming more and more difficult to erect masts that can go high enough. In enter the remote sensing instruments. These are ground-based but can reach high into the atmosphere. The dominant technology seems to be the lidar, and in this session we will take a look at many aspects of the use of these: floating, nacelle-mounted, multiple. We will also hear how satellites can be used to address this problem.
