Abstract[English]
A method of heating a wind turbine blade with three or more heating elements, the method comprising: generating three or more alternating voltages, each alternating voltage having a different phase; and feeding the alternating voltages to the heating elements, thereby generating alternating currents in the heating elements which cause the heating elements to heat the wind turbine blade. The wind turbine blade comprises first and second electrodes, an alternating voltage with a first phase is fed to the first electrode, an alternating voltage with a second phase is fed to the second electrode, and an alternating current flows through one of the heating elements between the first and second electrodes, driven by an alternating voltage difference between the electrodes.[French]
L'invention concerne un procédé de chauffage d'une pale d'éolienne avec trois éléments chauffants ou plus. Ledit procédé comprend : la génération de trois tensions alternatives ou plus, chaque tension alternative présentant une phase différente ; et l'alimentation des tensions alternatives aux éléments chauffants, ce qui génère ainsi des courants alternatifs dans les éléments chauffants qui amènent lesdits éléments chauffants à chauffer la pale d'éolienne. La pale d'éolienne comprend des première et seconde électrodes, une tension alternative avec une première phase est fournie à la première électrode, une tension alternative avec une seconde phase est fournie à la seconde électrode, et un courant alternatif circule à travers l'un des éléments chauffants entre les première et seconde électrodes, entraîné par une différence de tension alternative entre les électrodes.
