Abstract
The present invention relates to a method (300) for preventing ice formation at a blade (202) of a wind turbine (200), wherein the wind turbine (200) comprises at least one first electric heating mat (102) applied to the blade (202), and wherein the method (300) includes: providing the first electric heating mat (102) with a first electric power (P1) so that the first electric heating mat (102) maintains a first operating temperature (T1), and increasing the first electric power (P1) upon an indication of icing at the blade (202). The invention also relates to an arrangement and a wind turbine comprising such an arrangement.

A method (300) for preventing ice formation at a blade (202) of a wind turbine (200), wherein the wind turbine (200) comprises at least one first electric heating mat (102) applied to the blade (202), and wherein the method (300) comprises:
- providing the first electric heating mat (102) with a first electric power (P1) so that the first electric heating mat (102) maintains a first operating temperature (T1), and increasing the first electric power (P1) upon an indication of ice formation at the blade (202).
An arrangement (100) for preventing ice formation at a blade (202) of a wind turbine (200), wherein the arrangement (100) comprises at least one first electric heating mat (102) configured to be applied to the blade (202), a control device (120) configured to control electric power supplied to the first electric heating mat (102) via a power source (140) connected to the first electric heating mat (102), wherein the control device (120) is configured to control the power source (140) so that the power source (140) provides the first electric heating mat (102) with a first electrical power (P1) so that the first electric heating mat (102) maintains a first operating temperature (T1), and to increase the first electrical power (P1) upon an indication of ice formation at the blade (202).
