Abstract: With the development of big data, many power plants in China have also begun to improve their in-telligence. The real-time value of sensor points is an important indicator reflecting the current health status of the generator set, which has strong tracking significance. Studying and predicting the real-time value changes of sensor points in a short period of time can help power plant moni-toring personnel understand the current health status of the generator set and respond to unex-pected situations in advance. By modeling and analyzing the time series data of sensor point values, the LSTM model was used to make short-term predictions for subsequent sensor point values, and good fitting prediction results were obtained, fully demonstrating the feasibility of applying the time series model to short-term prediction of sensor point values. With the deepening of intelli-gence in power plants, the accuracy of sensor point prediction should be further improved to help power plant monitoring personnel better cope with abnormal conditions of generator units.
