Valve cooling equipment inlet valve temperature prediction method based on time sequence analysis

The invention discloses a valve cooling equipment inlet valve temperature prediction method based on time sequence analysis. The method comprises the following steps of (1), preparing data, and constructing a data set; (2) data trend analysis; (3) determining a time sequence analysis method, and establishing a linear prediction model and a nonlinear prediction model; and (4) predicting and analyzing the inlet valve temperature of the valve cooling equipment. According to the method, the hidden information and trend in the data are mined by utilizing time sequence analysis and model establishment on the monitoring data of a running state of the existing valve cooling equipment, so maintenance cost is reduced, and troubleshooting efficiency is improved; the perceptual capacity of workers forthe valve cooling equipment is improved, corresponding preparation is made for the future change trend of the equipment, and guiding significance is achieved for normal operation of a power grid andreliable power supply; in
