本文提出了两种可供选择的方法来设计有机朗肯循环（ORC）的动态模型，用于控制和诊断系统的设计。该模型采用Modelica语言开发，并用Dymola进行仿真。比较了基于移动边界和离散化技术的两种建模方法的精度、复杂度和仿真速度。仿真结果表明，两种模型均具有较好的精度。并且移动边界模型速度更快，因此更适合于控制设计应用。
The paper proposes two alternative approaches for the design of a dynamic model for an Organic Rankine Cycle (ORC) to be used for the design of control and diagnostics systems. The model has been developed in Modelica language and simulated with Dymola. The two modeling approaches, based on moving boundary and discretization techniques, are compared in terms of accuracy, complexity and simulation speed. Compared to experimental data simulations evidence that while both models have good accuracy. And the moving boundary model is faster, therefore more suitable for control design applications.
