| 摘 要： | 针对燃气轮机动态建模容积效应法运用过程中,使用真实体积运算时计算结果振荡较大,无法对燃气轮机动态过程进行实时有效的运算的问题,对容积效应法的原理进行分析,提出了采用虚拟容积计算方法计算容积大小.采用面对对象的模块化建模方法,基于Matlab/Simulink平台,运用容积效应法建立了燃气轮机动态仿真模型,解决了在常规建模时迭代次数太多的问题.分别计算了在相同工况变化条件下,采用真实容积和虚拟容积方法建立的两种模型的仿真结果.研究结果表明,采用虚拟容积的仿真模型更稳定,并且计算结果更准确.

| Abstract: | The numerical results of the volume effect of the dynamic simulation model of gas turbine were oscillating,the principle of volume effect method was analyzed.The virtual volume calculation method was proposed to calculate volume size.Based on the Matlab/Simulink,the dynamic simulation model of a gas turbine developed by the objected-oriented modularized modeling method was established by the volume effect method.The number of iteration was reduced.The models in the same situation based on real volume and virtual volume were calculated.The results indicate that the simulation model based on virtual volume is more stable and more accurate. |
