摘　　要：针对新型培训仿真机开发,以质量和能量守恒定律为基础,应用传热学的有关理论,在MATLAB/Simulink平台基础上依据图形组态的方法,建立了大型电站凝汽器的动态数学模型,同时采用模块化的建模方法,建立了单压、双压、三压凝汽器的动态仿真模型,并利用经验数据进行了正常工况扰动和故障设置的数值实验。通过比较不同背压凝汽器的调试结果,表明建立的多压凝汽器模型具有较高的精度和通用性,适合于各种工况下的仿真运行。Aiming at the newly-opened simulator for training, a dynamic mathematic model was constructed through graphical configuration on the MATLAB/Simulink flat roof for condensor of power plant, basing on the quality and energy law and theory of practical diathermalics. At the same time, a simulating model for single-pressure, double-pressure and triple-pressure condensor was constructed through modularization, and some numerical value experience for disturbing working conditions and malfunction was taken to test the model, basing on experiental data. Comparing the results of different pressure condenser with the practicalty comes to a conclusion that this model has high precision and may be in common use, which can be well applied to simulating process for all kinds of working condition.
