Hoar frost, rime ice and glaze ice in the operation of wind turbines and their effects Hoarfrost, rime ice and glaze ice occur at temperatures just below the freezing point and are collectively referred as “Nebelfrostablagerungen”. These fog-frost deposits are characterised, among other things, as follows: usually form when fog droplets freeze on predominantly vertical…
Ice accumulation on wind turbine rotor blades has a crucial impact on operation and maintenance. Lower return due to aerodynamic imbalances as well as safety of the power plant and its surroundings are of central importance. Regardless of whether a wind turbine is located next to a highway or in the mountains where skiers and…
Modified safety regulations of wind farm operations in France (in force since January 1, 2021) Click here to the French version of this article On June 22, 2020 a new decree was published by the French Government, to bring some modifications in the safety regulations of wind farm operations (ICPE regulation). Before the modifications…
Minimise risks such as ice throw and increase yield with ice detection and temperature measurement directly on the rotor blade surface The risk factor: icing A wind turbine is designed to be used for at least 20 years, sometimes even up to 30 years. During its lifetime, it should reliably deliver maximum energy yield with…
New DNV GL certificate for eologix ice detection systems: Reduction of the number of sensors per wind turbine while increasing the redundancy of the entire system Every two years, all ice detection systems approved by DNV GL are subject to recurring certification. In September 2020 we have completed the re-certification of our ice detection systems,…
These 6 factors should be considered when buying an ice detection system You are planning to buy an ice detection system and you still have not decided which system to buy or you would like to know whether you have taken into account the essential factors for the purchase. In the following article, the most…
What are the options for ice detection? There are a variety of systems for the detection of ice on the rotor blades or rather technologies for the detection of icing. Most frequent ones: Measurement of the ambient temperature Measurement of the ambient temperature and the humidity Anemometer comparison Nacelle-based ice detectors Camera systems Ice detection…
One major goal for manufacturers and operators of wind turbines is to achieve the highest possible efficiency by continuously optimising the wind turbines. At the moment, however, operators of wind turbines have to accept annual losses in earnings due to icing in the five-digit Euro range. In this whitepaper, you will learn how to optimise your wind turbine using an ice detection system…
