摘要

At present, there have been a large number of researches on nuclear power plant (NPP) process simulation, such as the researches on the NPP full-scope dynamic process simulation. However, these simulation researches mainly adopt the simulation modeling calculation based on the offline mode and historical data, so they cannot keep up with the real field data. Hence, the application of online simulation technology in NPP has become a new research direction. Based on the NPP real-time information monitoring system and the full-scope simulation verification platform, a high accuracy mathematical model is established which can realize the parallel operation of simulation system and NPP systems. Since the axial power deviation is an important index that could reflect the safe operation state of NPP. the online early warning measures based on online faster-than-real-time simulation is proposed for axial power deviation. By monitoring the field key parameters, the online calculation and analysis are realized. In addition, they can also predict the future states of NPP equipment and systems. These results can provide the references for operators to balance the NPP economic efficiency and safe requirements.
