Wind energy in Norway - Icing of wind sensors? Not with the ultrasonic wind sensor VENTUS! - Case Study
Renewable energy in Norway is getting more and more important! The government has spent the goal that the use of renewable energy should increase strongly over the next years. Wind power plays a major role in this endeavor. Norway is climatically and topographically one of the most interesting locations for wind energy in Europe - but it is barely tapped by now. Our customer, the power company ...

Using Lidar for WRA Campaigns: Your Questions Answered (Part I)
In the course of conversations with wind developers new to Lidar technology, a number of questions seem to come up regularly. In this and future blog posts, I will attempt to answer these questions in some detail to benefit others who might be pondering them as well. Two very practical questions have to do with how WINDCUBE® Lidars might affect overall wind resource assessment (WRA) campaign ...

UK offshore load factors accelerate on tech breakthroughs: 10-year study
UK offshore load factors accelerate on tech breakthroughs: 10-year study The Crown Estate’s Offshore Wind Operational report 2015 shows there has been a gradual increase in the load factor for the UK fleet since 2004 on the back of more productive wind turbines, wind farms being built at windier sites and improved plant availability. The Crown Estate manages UK sovereign assets such as ...

On the probabilistic distribution of wind speeds: theoretical development and comparison with data
The probabilistic distributions of wind speed are a critical piece of information needed in the assessment of wind-energy potential, and have been conventionally described by various empirical correlations. Among the empirical correlations, the Weibull distribution has been most popular due to its ability to fit most accurately the variety of wind-speed data measured at different geographical ...

Smart solar monitoring / PV monitoring with smart weather sensors - Case Study
When selecting a suitable pyranometer for photovoltaic monitoring the company Solare Datensysteme GmbH decided for the Lufft WS501-UMB All-in-one weather station. According to the company the Pyranometer delivers the most precise measurements for the overall irradiance and serves to measure the exact local prevailing overall irradiance at large plants. The Pyranometer is installed independent ...

Weather claims and wind safety
Anybody working in the construction industry either here in the UK or anywhere else in the world is likely to know that the weather can present us with particular hazards. While rain, ice and snow are particularly dangerous to work in, we must always be aware that the wind is also likely to make conditions unsafe, particularly for those who work at height and those who operate access machinery ...

Wind turbine controlling of the future
Higher, more robust, more reliable: Parallel to the growing requirements for wind turbines, the requirements for monitoring sensors grow as well. But how can wind sensor manufacturers fulfil these wishes? And how should a future wind sensors look like? After analysing the current conditions and trends on the wind energy market, our CEO Klaus Hirzel compiled a wish list for future wind sensors. ...

Measuring Offshore Wind Resources
To select the right offshore wind site, estimate the future energy output of a wind farm, and determine the best layout for the turbines, project developers must conduct wind resource assessment (WRA) campaigns on site. This is a critical phase of the successful development of wind farms. WRA campaigns on terrestrial sites have traditionally been performed using meteorological towers equipped ...
