Description

Technical Field

[0001] The utility model relates to the technical field of fault warning equipment, in particular to a wind farm fault warning device. Background Art

[0002] A wind farm refers to a place that uses wind turbines to convert wind energy into electricity. In order to ensure that each wind turbine in the wind farm can work normally, fault warning equipment is often installed inside the wind turbines so that abnormal conditions can be handled in a timely manner.

[0003] The Chinese patent authorization announcement number CN204591593U discloses a blade fault monitoring device for a wind turbine, including: a switch control signal acquisition device and a reference time signal acquisition device, and the controller realizes blade fault monitoring by calculating the time difference between the switch control signal and the reference time signal. This fault monitoring device directly monitors the blades, which increases the reliability of the system; the use of non-contact laser sensors to collect signals makes it easy to obtain monitoring signals, which can effectively eliminate the influence of external signals, avoid the introduction of noise signals into the collected signals, and avoid complex data processing; the system is simple and easy to operate, reducing the cost and installation difficulty of the system; by comparing the two time differences, the monitor outputs a shutdown signal to the safety chain circuit to shut down when the blade fails, realizing the early warning of the fault; the structural design is scientific and reasonable, low cost, easy to use and maintain, and has a good prospect for promotion and application.
