Abstract: | The volute door significantly affects the inlet of turbine. Therefore, it is very important to monitor its operating status to ensure the safe and stable operation of the unit. In order to improve the effect of spiral door operating condition monitoring, it is necessary to build a set of real time physical field monitoring system with high precision and high real-time. Using finite element analysis technology, based on the field monitoring data, and then using the agent model technology, a high-precision physical field real-time monitoring system of the volute door was constructed, so as to realize the real physical model and digital model of the volute door in millisecond level, high-precision real-time simulation. The results show that the physical field monitoring of volute door with high precision and real time is realized by using the monitoring system. |
