Problems solved by technology

[0003] The wind turbine generator set has been running for a long time, and due to the long-term wet and salt spray weather, the internal corrosion of the brake caliper and the aging and leakage of the sealing ring have caused the brake caliper to be abnormally engaged in braking during the normal operation of the unit, and the brake caliper operates too many times. The accumulation of energy inside the caliper may cause the temperature of the brake caliper to be too high, resulting in a safety hazard

Abstract

The embodiment of the invention discloses a fan brake control method and device. The method comprises the steps that a brake controller receives a brake signal; the brake controller controls a fan brake to perform a brake action according to the brake signal; the brake controller is used for receiving a temperature signal fed back by a temperature sensor on the fan brake, the temperature sensor islocated on a brake caliper side of the fan brake, and the temperature signal is used for indicating the current temperature of a brake caliper; and if the temperature signal indicates that the current temperature meets a preset condition, the fan is controlled to stop running, and an alarm is given. The embodiment of the invention further provides the fan brake control device, and the control device is used for detecting the temperature of the brake caliper in time so as to prevent the temperature of the brake caliper from being too high and generating danger.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a brake control method and device. Background technique [0002] At present, wind power generation has become the main way of new energy. Wind power generators can not operate under any wind force, but have a limit of rated speed. If the wind speed is too high, the power generation efficiency of the generator will be relatively low. If the wind speed is further increased, failures such as flying cars will be caused, and the wind turbines will be destroyed. Therefore, the current wind generators are equipped with brake components to control the wind generators to operate within the rated speed range, and the brakes are set to control the transmission chain, which is convenient for maintenance personnel to maintain the wind turbines. [0003] The wind turbine generator set has been running for a long time, and due to the long-term wet and salt spray weather, the internal corro...
