| Abstract:The ring main unit is a key device for the ring network power supply， but in the long-term operation， the temperature of the unit rises because of many factors to reduce the power supply safety and reliability. In this paper， a method of forecasting the temperature of the electrical joints of the ring main unit is proposed. Firstly， the measured temperature of the electrical joints of the ring main unit is analyzed， and then the noise in the measured temperature data is removed by wavelet denoising. Finally， the least squares support vector machine is used to predict the trend of the data. The model is applied to the temperature prediction of the ring main unit. The experimental results have verified the effectiveness of the proposed model. |
