Measurement apparatus and method of braking torque of spindle brake of wind turbine generator system

Abstract

The invention provides a measurement apparatus and method of the braking torque of the spindle brake of a wind turbine generator system. The measurement apparatus of the braking torque of the spindle brake of the wind turbine generator system includes an intelligent control arithmetic unit, a proximity switch arranged on a pulse count fluted disc of the wind turbine generator system, a wind indicator used for measuring an included angle theta between a wind direction and an engine room, an anemometer used for measuring wind speed v, a voltage sensor used for measuring direct-current barbar voltage Udc, a current sensor used for measuring direct-current load current I and a spindle brake system, wherein the spindle brake system comprises a braking in-place feedback device used for detecting a braking position and measuring a braking interval and a driving device used for driving the spindle brake to execute a braking action. The measurement apparatus and method of the invention have a wide application range and applicable to wind turbine generator systems comprising spindle brakes.

Description

technical field [0001] The invention relates to a measuring device and method for the braking torque of the main shaft, and proposes a design method for measuring the braking torque of the main shaft by using the relationship between the moment of inertia and the torque. The utility model is used for measuring the braking torque of the main shaft brake of the wind power generating set, and belongs to the technical field of wind power generation. Background technique [0002] In recent years, the shortage of resources and the deteriorating environment have made countries all over the world pay attention to the development and utilization of renewable and non-polluting wind energy resources. Since the 1980s, the main trend of wind energy utilization is wind power generation. With the development of modern technology, wind power is developing rapidly, and its proportion in the whole energy utilization is increasing. With the maturity of wind power technology, more and more wi...

[0005] Although the detection of the thickness of the friction block is the most intuitive and authentic detection method, this detection method can only detect the brake block itself, and cannot detect other components of the spindle braking system. That is to say, this detection method Not comprehensive enough to have a good understanding of the braking performance of the current brake

However, manual inspection is limited by the space of the engine room and the harsh on-site environment, so there are certain flaws, and it is also affected by the work skills and attitude of the inspectors.
