摘    要:针对热力系统仿真中出现的大流量流经小容积环节而使系统的积分步长受到限制,提出了一种处理小容积环节压力流量微分方程的新方法.用该方法提供的解法,在有效增加系统仿真积分步长的同时,准确地计算出小容积环节的压力动态变化过程.该技术在某电气公司的汽轮机实时仿真实践中,证明了其实用性和可靠性.

关 键 词:热力学系统  系统仿真  数值解  建模  小容积环节

Abstract:In thermodynamic performance simulation of power systems, when a model contains some small volumes with large flows, very small time step must be used to get convergent results. A novel technique for simulation of large flows into and out of small volumes is introduced. The results from the simulation application in industrial environment show that this technique allows the time step to increase while still maintains the model convergence.
Keywords:thermodynamic systems  system simulation  numerical solution  modeling  small volume
