Artificial intelligence based abnormal detection system and method for wind power equipment

The existing traditional monitoring methods are not ideal for identifying abnormal states in remote real-time monitoring of power system equipment due to adverse weather conditions such as haze and snow. The traditional monitoring methods for wind power equipment mainly rely on manual inspections and regular maintenance, which have problems such as high labor costs, low monitoring efficiency, and low monitoring accuracy. In order to improve the effectiveness of anomaly recognition for power system equipment, this paper proposes a remote real-time monitoring anomaly recognition method for power system equipment based on artificial intelligence technology. Firstly, this article uses pan tilt cameras to capture real-time images of power system equipment and transmit them to a remote monitoring center. The remote monitoring center captures real-time images of the equipment in the video stream and performs real-time image preprocessing. Then, the variational mode decomposition method is used to extract the abnormal state features of power system equipment in the image, and this feature is input into the support vector machine as a training sample to achieve real-time recognition of abnormal state of power system equipment. This article was also conducting fault diagnosis for four sets of wind turbines in the experimental section. According to the experimental results, it can be concluded that the rotational speed of wind turbine 1 increased from around 12 rpm to around 30 rpm during the day. During the day, the temperature of wind turbine 2 increased from around 25 °C to around 40 °C, while wind turbine 3 remained in a stopped state and the current speed decreased to 0. Wind turbine 4 also decreased from around 10 rpm to 0 during the day. From this, it can be concluded that the wind power equipment anomaly detection system based on artificial intelligence can clearly determine the abnormal situation of wind turbines. The wind power equipment anomaly detection system based on artificial intelligence can timely and accurately identify the abnormal situation of WPE, and can provide a new wind power equipment anomaly detection method based on artificial intelligence for the wind power industry. This can provide more accurate and reliable support for the operation and maintenance of wind power equipment, and also provide practice and exploration for the application of artificial intelligence in the industrial field. © 2024
