Wind measurement towers

The  towers T60, T70 and T80 manufactured and traded by Blue Line Energy are solid structural steel constructions, weather-proofed by means of a two-component paint applied in two layers. The smaller components and the support cables are zinc-coated. The segments can be easily and rapidly joined, and the ground assembly work requires a relatively short period of time.

The currently produced towers are 60m, 70m and 80 m high. Intermediary dimensions can be manufactured upon request.

The towers are painted in white-red stripes to comply to aviation norms. Alternatively, upon beneficiary's request a buoy system for night time can also be added.

The towers are lightning-proof by means of an lightning kit, connected to the ground electrode by means of a copper solid wire.

Severall important elements are required in order to implement a wind-energy project successfully.

One of these elements resides in getting an accurate picture of the wind potential in a certain location. This picture can be obtained by means of a professional measurement tower, at a height as close as possible to the height of the future wind turbine.

In order to deem the results as plausible, it is important not to have gaps in the recorded data sets. The devices must be correctly installed and all anemometers must be calibrated in accordance with the applicable regulations. In order to come up with a correct forecast for the production of the entire wind farm, experts analyze the data recorded during measurement sessions, while taking into consideration local factors and the complexity of the location.

Based on the final report one shall decide upon issues such as: project reliability, type of turbine, optimal tower height, equipment layout within the farm, display of access roads and power lines, etc.

Wind data are important for manufacturers, as well, this being a condition for concluding a purchase agreement, as each turbine is optimized for the designated location.

After the actual start-up, one measurement tower is kept in the wind farm in order to optimize the operation of the turbines and to detect any possible problems. The recorded information is entered into the SCADA system of the farm.

The instruments (usually delivered) are manufactured by NRG Systems, world leader in the field. The measurement levels for e.g. the 60 m tower are: 60 m, 50 m, 40m. The equipment in this case usually consists of: 2 sensors for the wind direction, 3 calibrated anemometers, 1 heat sensor, a logger, a GSM kit for remote data transfers and a solar panel in order to ensure its energetic independence. The devices are protected against hard weather conditions and vandalism with the help of a closed metal casing.

On request the towers may be delivered with instruments from other manufacturers or without instruments.
