Automatic control system of wind driven generator blade unloading device

Abstract

The invention discloses a wind power generation device, and in particular relates to an automatic control system of a wind driven generator blade unloading device. In the automatic control system of the wind driven generator blade unloading device, the output ends of a wind speed detector (1) and a wind direction detector (2) are connected with the input end of a microprocessor (3); the output end of the microprocessor (3) is connected with the input end of a compression spring starting device (5); and the output end of the compression spring starting device (5) is connected with the input end of a steering linkage executing switch (4). The system can control the wind driven generator blade unloading device well and has the advantages of low cost, high self-control capacity, simple structure, convenience of production, installation and overhauling and sensitive response.

Description

technical field [0001] The invention relates to a wind power generator, in particular to an automatic control system for a blade unloading device of a wind power generator. Background technique [0002] At present, fixed-pitch wind wheel devices are commonly used in wind turbines, and the electronically controlled servo system is used to control the stall of the wind turbine. That is, when the wind speed is too high, the system makes the wind wheel turn to yaw as a whole, reducing the area of ​​the windward force, so as to ensure the wind turbine. The number of rotations does not exceed the rated number of rotations of the generator to protect the generator from being damaged. At the same time, it also avoids the damage of the wind turbine and the wind turbine pillar, so as to ensure the safe operation of the wind power generating set. [0003] Although the existing fixed-pitch wind wheel device has protected the operation safety of the wind power generating set, it still h...

AI Technical Summary

Problems solved by technology

[0003] Although the existing fixed-pitch wind wheel device has protected the operation safety of the wind power generating set, it still has the following technical problems: the existing fixed-pitch wind wheel has extremely high cost, complex structure, and inconvenient production, installation, and maintenance; Insensitive, when there is an unstable wind direction or short-term gusts, it cannot respond and adjust in time, which may easily cause damage to the wind turbine

[0004] In order to solve the above-mentioned technical problems, the inventor has developed a blade unloading device for wind-driven generators, but there is no control system for this blade unloading device for wind-driven generators.
