Embodiment Construction

[0021] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0022] figure 1 It is a schematic flowchart of an auxiliary fault handling method for wind turbines provided by the present invention. see figure 1 , the auxiliary fault handling methods for wind turbines include:

[0023] S11, performing fault classification on all faults of the wind turbines.

[0024] All faults of wind turbines are divided into four categories: non-resettable faults, continuous resettable faults, resettable limited number of faults, and resettable faults after special treatment. The initial content of each type of fault is specified by the wind farm or the centralized control center, and is a part to be adjusted according to the actual situati...

Abstract

The invention relates to a fault auxiliary processing method and device for a wind turbine generator. The method comprises the following steps: acquiring SCADA monitoring data of a wind turbine generator in real time; according to the SCADA monitoring data obtained in real time, judging the fault type; and through the Bayesian belief network, judging whether a non-frequent fault can be reset or not, and judging the category of a reset operation executed when the non-frequent fault can be reset. According to the fault auxiliary processing method and device for the wind turbine generator, falsereset and untimely reset are prevented, the wind energy utilization hour of the wind turbine generator is increased, and the generating capacity is improved to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a method and device for assisting fault handling of wind turbines. Background technique [0002] Wind power has become my country's third largest source of electricity after thermal power and hydropower. my country has led the world in newly installed wind power capacity for five consecutive years, and its proportion in the power supply structure has increased year by year. As my country's investment in wind power has increased year by year, the operation and maintenance of wind farms has also become the focus of the wind power industry. In terms of monitoring the operation of wind farms, the operation of the wind farm is carried out by the operation watchman on duty 7 x 24 hours a day. However, with the increase in the number of wind turbines, especially the establishment of the centralized control center, a large number of wind turbines need to be monitored, maki...
