A wireless control system for electrothermal ice melting of wind turbine rotor blades

Abstract

The invention provides an electric heating ice melting wireless control system of a rotor blade of a wind driven generator. The electric heating ice melting wireless control system comprises electric heating ice melting layers, blade monitoring terminals and a control cabinet, wherein the electric heating ice melting layers and the blade monitoring terminals are fixed to the blade, and the control cabinet is arranged at the bottom of a tower; the independent blade monitoring terminals are arranged on an SS surface and a PS surface of the blade respectively, and each blade monitoring terminal is connected with the control cabinet through a wireless network; a tower monitoring terminal is arranged at the bottom of the tower. Through the scheme, environmental parameters of a wind generating set and the temperature of the surface of the blade are remotely monitored through the wireless networks, the electric heating ice melting layers can be remotely started through the wireless networks to conduct electric heating ice melting, and therefore safety of the wind generating set is improved.

Description

Technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wireless control system for electric heating and ice melting of rotor blades of a wind power generator. Background technique [0002] With the current society's consumption of energy, non-renewable energy is increasingly depleted, so the use of renewable energy has always been the focus of the current human society's technological development. Among clean energy, wind power and solar power have received the most attention. It is estimated that there are about 10 billion kilowatts of wind resources on the earth that can be used to generate electricity, which is almost 10 times the amount of hydroelectric power generation in the world; and the energy obtained by burning coal every year in the world is only one-third of the energy that wind can provide. One. Especially in western China, where there is a large area with sparsely populated areas and abundant wind resource...

AI Technical Summary

Problems solved by technology

[0004] 1. The physical shape of the blade changes due to icing, which reduces the blade's ability to withstand wind

Moreover, the balance of the blade group is destroyed, the weight of the blade increases, and the wear of the generator set increases, which not only affects the power generation of the generator set, but also has a great impact on the life and safety of the generator set.

[0005] 2. The icing of the blades increases the weight of the blades, increases the load of the generator set, and increases the mechanical wear of the generator set

This will lead to inaccurate final results, which will easily affect the operation of the equipment
