Embodiment Construction

[0027] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as figure 1 As shown, one aspect of the present invention provides a method for recording fault data of wind turbines, the method comprising:

[0029] Exemplarily, obtain the real-time data of the wind-driven generator PLC, and obtain the active power of the wind-driven generator in the real-time data, and judge the active power value of the wind-driven generator, if the active power of the wind-driven generator is not greater than If it is zero, it is determined whether the status code of the wind turbine is a fault.

[0030] Specifically, after the active power of the wind generator is obtained from the real-time data, the active power is determined. If the active power of the wind generator is not greater ...

Abstract

The invention provides a wind generating set fault judgment method, and belongs to the technical field of wind power generation. The method comprises the following steps: acquiring real-time data of a PLC (Programmable Logic Controller) of the wind driven generator, acquiring active power of the wind driven generator from the real-time data, judging an active power value of the wind driven generator, and judging whether a state code of the wind driven generator is a fault if the active power of the wind driven generator is not greater than zero; if the state code of the wind driven generator is faulty, judging that the current state of the wind driven generator is faulty, and judging the duration of the fault; and if the duration time of the fault exceeds the first preset threshold value, the fault of the wind driven generator needs to be processed on site. By adopting the method to judge the fault of the wind driven generator, the judgment result has small deviation from the actual state of the wind driven generator, and the judgment result is accurate.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a method for judging a fault of a wind power generating set. Background technique [0002] Wind turbine is the basic unit of wind power enterprise production. Since wind turbines can only be built in windy areas, and the wind direction and speed of high-altitude winds are changeable, this makes wind turbines operate under variable load conditions for a long time. Moreover, in areas where the wind is relatively strong, the working environment of the fan is even worse. Under such unfavorable working conditions, the probability of failure of wind turbines will increase; with the increase of the running time of wind turbines, the number of failures during operation will increase; due to the inherent characteristics of the wind energy industry, wind turbines in wind farms The distribution range is very wide, and there is no one on site under normal operatio...
