Embodiment 1

[0021] A wind power pitch system fault recording device, which consists of: a data collector, a memory, a processor, a clock chip and a data communication module, the input end of the data collector is used to collect the operating data of the wind power pitch system, and the data collector The output terminal is connected to the processor, and is used to transmit the collected operating data of the wind power pitch system to the processor;

[0022] The data collector is connected to the input and output ends of the safety chain signal of the pitch drive cabinet and the three-phase AC input end of the pitch motor;

[0023] The clock chip and the data communication module are respectively connected with the processor.

Embodiment 2

[0025] According to the wind power pitch system fault recording device described in Embodiment 1, the processor caches the latest wind power pitch system data of T 0 , and judges whether the wind power pitch system is faulty according to the safety chain signal of the wind power pitch system, When it is judged that the wind power pitch system is faulty, the wind power pitch system data of T 2 hours after the wind power pitch system fault and the wind power pitch system data of T 1 time before the wind power pitch system fault are integrated into a fault recording record.

Embodiment 3

[0027] According to the wind power pitch system fault recording device described in embodiment 1 or 2, the data collector also samples the output terminals of the rotary and / or temperature signals connected to the pitch motor and the voltage signals on both sides of the energy consumption braking resistor .

Abstract

The invention discloses a wave recording method of a wind power variable pitch system fault wave recording device. Recording information corresponding to various key data is large, correspondingly occupied memory space is large, recording efficiency is low, and later extraction of data before and after a fault by technicians is not facilitated. The system comprises a data collector, a memory, a processor, a clock chip and a data communication module, the input end of the data collector is used for collecting operation data of the wind power variable pitch system, and the output end of the data collector is connected with the processor and used for transmitting the collected operation data of the wind power variable pitch system to the processor. The method is used for fault recording of the wind power variable pitch system.

Description

technical field [0001] The invention relates to a wave recording method for a fault wave recording device of a wind power variable pitch system. Background technique [0002] The occurrence of faults in the pitch system of wind turbines is not only related to the system itself, but also closely related to the real-time wind conditions of the wind farm in many cases. Some faults only appear under special wind conditions. The emergence of these special wind conditions has certain randomness and unpredictability, and the technicians are often not on site when the fault occurs. [0003] In order to record various key data before and after the failure of the wind power pitch system, the wave recorder can be used to continuously record various key data; however, the wave recording information corresponding to various key data is relatively large, and the corresponding memory space occupied Larger, the recording efficiency is low, which is not conducive to the extraction of data b...
