Abstract

The embodiment of the invention provides a method, device and equipment for detecting the rotating speed fluctuation of a generator, and a storage medium. The method for detecting the rotating speed fluctuation of the generator comprises the following steps: acquiring rotating speed data of the generator in an appointed time range; extracting the maximum rotating speed value envelope line and theminimum rotating speed value envelope line according to the rotating speed data of the generator; and according to the maximum rotating speed value envelope line and the minimum rotating speed value envelope line, determining whether the rotating speed fluctuation of the generator within the appointed time range reaches an alarm condition or not. According to the embodiment of the invention, the method can achieve the quick and accurate recognition of the abnormal condition of the rotating speed fluctuation of the generator, can achieve the accurate recognition of the fault of the generator based on the abnormal condition, provides an accurate and effective data basis for a worker, and enables the worker to timely take targeted measures to carry out the further troubleshooting or instrument maintenance.

Description

technical field [0001] The present application relates to the technical field of generators, and in particular, the present application relates to a detection method, device, equipment and storage medium for fluctuations in rotational speed of a generator. Background technique [0002] The stability of wind turbines has a direct impact on the economic benefits of wind power projects. Wind turbines rely on numerous sensors to perceive the external environment in order to make reasonable decisions and perform correct actions. Therefore, the data quality of sensors is very important, and the data of some important sensors is particularly critical, such as the fluctuation of the generator speed. [0003] If the fluctuation of the generator speed is abnormal, on the one hand, it means that the sensor is abnormal, and on the other hand, the operation of the generator is abnormal, resulting in abnormal fluctuations in the actual speed of the generator. If the fan controller adopts...
