Ice Heating Mat Wind Turbine Patent

However cold weather climates present unique challenges to wind operators and o m technicians.

Ice heating mat wind turbine patent.

The invention relates to heatable wind energy turbine blades and to a method of heating and deicing the turbine blades using conductive fabrics to displace and or cease the buildup of ice on the turbine blades by electrothermal fabric heater disposed or integrated on the turbines for effectively deicing the blades. Written by barbara rook contributor it can be tough to predict and even tougher to manage. Atmospheric icing that impact wind turbine development can be distinguished. Draft version of elforsk report 12 13 icing of wind turbines prepared for winterwind 2012 7 8 feb 2012.

Patent details a wind turbine that generates electricity from heat energy rather than rotational energy created by the rotation of the unit s blades. Renewable and sustainable energy reviews 65 2016 662 675 665 misuse d by operat ors to im ply. The invention relates to heatable wind energy turbine blades and to a method of heating and deicing the turbine blades using conductive fabrics to displace and or cease the buildup of ice on the turbine blades by electrothermal fabric heater disposed or integrated on the turbines for effectively deicing the blades. After experiencing significant wind farm downtime due to ice buildup on turbine blades the operators of the 150 turbine lac alfred wind farm near amqui quebec sought.

The blade further has at least one conductive element wherein the conductive element is electrically. In cloud icing rime ice or glaze and precipitation icing freezing rain or drizzle wet snow. A blade for a wind turbine includes at least one heating mat for generating heat wherein the heating mat is mounted at an outer surface of the blade. The estimated market potential for wind farms in cold climates is more than 200 gw according to clir renewables a renewable energy ai software company.

According to the. Standards and guidelines as well as technical solutions for planning. The different forms of atmospheric icing can be described as follows. Power curves of a 300 kw wind turbine with various ice shapes 15 17.

A wind turbine is disclosed which comprises a control system configured to execute at least one ice removal routine which comprises a heating stage of at least one of the blades 3 and a mechanical removal ice stage. The blade further includes at least one through hole running from an inner space of the blade to the outer surface of the blade. Finally ice throw and ice fall from the iced wind turbine rotor blades represent a sig nificant safety risk for service personnel and passers by. Multiple turbine blade design methods are explored as well as heater materials.

But wind farm operators are finding success navigating around mother nature in cold climates. A wind turbine removing ice method is also disclosed which comprises a stage wherein the presence of ice is detected on at least one of the blades and once said presence of ice.
