Wind turbines should be able to work really in hard conditions. Sometimes they must withstand so cold weathers, sometimes so high temperatures which depends on where the turbine locates.

Especially the blades are effected in an important manner from the cold weather. And sometimes the ices can be problem for wind turbines. That's why during development state, up to climate conditions of desired area which turbine will be located, some extra calculations must be done. One of this extra calculations is ice loads which is defined in guidelines.

To let the turbine produce power in worse weather conditions wind turbine ice protection system (WTIPS) is invented. It is deicing the blade's leading edge by pulsing power to safely shed ice. WTIPS is a electro-thermal device system using technology originally developed through a NASA Small Business Innovative Research. It is light weight, easy to install, digitally controllable with Plc systems and reliable.
