Abstract

The invention provides a fault diagnosis method and device for a wind generating set. The fault diagnosis method includes the following steps: acquiring actual operation data of the wind generating set at each sampling time point in the current time period, wherein the actual operation data comprises a first group of actual operation data related to a first group of operation parameters and a second group of actual operation data related to a second group of operation parameters, the first group of operation parameters are independent variables related to the fault, and the second group of operation parameters are dependent variables of the first group of operation parameters; dividing the current time period into a plurality of sub-time periods based on the obtained first group of actualoperation data in the current time period, the difference between the first group of actual operation data in two sub-time periods which are continuous in time satisfying a first preset condition; anddetermining whether the wind generating set has a fault or not based on the second group of actual operation data in the plurality of sub-time periods.

Description

technical field

[0001] The present invention generally relates to the technical field of wind power generation, and more specifically, relates to a fault diagnosis method and equipment for a wind power generating set. Background technique

[0002] In the field of wind power generation, affected by the instability of wind resources, factors such as the availability of wind resources, power generation quality, and fault maintenance of wind turbines directly determine the power generation capacity of wind turbines themselves, which in turn affects the operation and maintenance of wind farms. and profit. At the same time, there are also great uncertainties in the management of the life-span parts of wind turbines, and it is difficult to arrange regular maintenance or renewal of life-span parts through experience. Therefore, there is a need for a method that can quickly and effectively perform fault diagnosis on wind power generators. Contents of the invention
