500MW/800MW超临界火电机组一机多模仿真机的研制与开发

针对国内对超临界发电机组操作运行培训的需要，开发了俄罗斯制造的500MW／800MW越临界发电机组一机多模仿真机。在分布式面向对象的仿真支撑环境中，对分散控制系统（DCS）仿真采用先进的虚拟DPU技术，对仿真模型采用图形化建模技术。由于采用了1套硬件2套模型的方法，降低了仿真机造价。锅炉水冷壁等设备建模采用分段集总参数方法，提高了仿真精度。该仿真机已在国华仿真培训中心投运，达到了预期效果，证实了仿真机采用的技术与方法的正确性。介绍该仿真机的技术特点、仿真范围与功能、仿真机组成、仿真精度及效果等。

Development of simulator with multi-models for 500 MW/800 MW supercritical thermal power unit

One simulator with multi-models for 500 MW/800 MW supercritical thermal power unit made in Russia was developed to meet the instant need of operation training for supercritical thermal power unit. In the distributed object-oriented simulation environment, virtual DPU technology is used to simulate the DCS of Unit, and the simulation model is realized by graphic modeling technology, in addition, the application of one simulator with multi-models considerably reduces the cost of simulator. The divided-section lumped-parameter modeling method for the boiler water walls increases the simulation accuracy. This simulator has been applied in Guohua Simulation Training Center to train operators and reached expected effect, which verified the simulation method and technology. The technical characteristics, simulation scope and function, hardware configuration, simulation accuracy and effect were covered in this paper.
