Scheme Design of Health Monitoring on Operation Status for a Hot Water Energy Storage Tank and Engineering Practice

As an indispensable storage structure for renewable energy, the safety of hot water storage tank is of great significance. In order to test the rationality of the tank design and the safety of the tank during operation, the field strain and temperature are collected. The design scheme of health monitoring is particularly important in the whole monitoring process. Based on the Tongliao hot water storage engery tank project, combined with the actual situation of the project, a reasonable monitoring scheme was designed, according to the data processing results, the stress distribution and temperature change of the tank wall along the height direction could be obtained, and the influence of temperature on the strain at the measuring point could be obtained. By comparing the measured stress values with the finite element simulation results, the correctness of the theoretical analysis and the rationality of the monitoring scheme were verified, and suggestions were put forward for the establishment of the numerical model of the non-anchored vertical storage tank.
