Global certification group DNV GL has launched its first LiDAR verification site in Asia to cater for the growing windpower market.
Based in Youngkwang in South Korea, the site provides optimal wind conditions for the verification of wind systems.
LiDAR (an acronym of Light Detection and Ranging) is a remote sensing technology which uses the pulse from a laser to collect measurements which can then be used to create 3D models and maps of objects and environments.
LiDAR measurement systems have been widely adopted by the wind industry as a cost-effective tool for various measurement applications such as wind resource and power curve measurements, as well as turbine control.
This information is crucial in the development process of new wind turbines to assess if they produce the power output as predicted in theoretical design phase of the turbine development.
The data of a verification campaign is also vital for site assessments, for example for the development of new wind parks.
As turbines are increasing in capacity and height, LiDAR technology can take measurements of up to 200m at more height intervals. In combination with its portability, LiDAR is quickly becoming the preferred measurement method by the wind industry.
Previously, LiDAR verification campaigns for Asian stakeholders had to be conducted at oversea sites. With the opening of the verification site in Korea, stakeholders now have the opportunity to conduct verification campaigns locally.
Korean wind farm developer DaeHan Energy and distributor of LiDAR device manufacturer VisionPlus have already successfully completed a verification campaign at the site in Korea.
The new test site has been developed with the input from DNV GL’s team of German LiDAR experts – in Germany alone, the demand for LiDAR verification has increased by 100 per cent for DNV GL.
The company expects similar growth rates in Asia, as the number of new turbine designs from local manufacturers and proposed wind parks is expected to increase. With LiDAR being a new technology in the industry, third-party verification of the devices is vital to ensure the quality of the data.
Nicolas Renon, DNV GL’s executive vice-president for APAC, said: “Previously, customers who wished to have their LiDAR verified had to send their equipment to our European offices. With this new site, we will be able to deliver more cost-efficient and higher quality data, tailored to the characteristics of the Asia Pacific region and to support the growth of the fast growing local wind sector.”
