Abstract

The embodiment of the invention provides a monitoring method and device of a wind driven generator. The current running state information and the current wind speed information, which are transmittedevery other preset first cycle, of a fan and the current actual power of the fan are received, so that the current theoretical power is calculated according to the current running state information and the current wind speed information; the set of the current actual power information and the set of the current theoretical power information within a preset second cycle are respectively counted; when the set of the current actual power information is abnormal relative to the current theoretical power information, an alarm prompting message is generated, data are received in real time, and the monitoring state is kept, so that the human cost is reduced, and the condition of missing detection is avoided; and the difference between the set of the current actual power information and the set ofthe current theoretical power information within the second cycle is compared, so that the relative abnormal condition is determined, the accuracy is further increased, working personnel are remindedto overhaul in time, and the utilization rate of energy is increased.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a monitoring method and device for a wind power generator. Background technique [0002] With the development of society, human beings rely more and more on electric energy. Among them, the technical method of converting wind energy into electrical energy through wind power generation is becoming more and more common. Wind turbines are often installed in areas rich in wind resources. Wind turbines are large-scale equipment with a large number and a wide range of installations. [0003] Therefore, the cost of monitoring whether the wind turbine is operating normally is too high, the monitoring is difficult, and the monitoring results are inaccurate. Contents of the invention [0004] In view of this, the object of the present invention is to provide a monitoring method and device for a wind power generator. [0005] In order to achieve the above object, the tech...
