摘要
为实现凝汽器的动态特性分析,采用模块化建模方法,运用Modelica统一物理建模语言以及Mworks仿真平台,根据凝给水系统的工作原理以及能量、质量守恒方程等,开发了热力系统模型库并建立凝汽器的仿真模型。利用所建立的模型,分析凝汽器在汽轮机排汽量以及循环冷却水流量阶跃变化等情况下的动态特性。结果表明,凝汽器内部参数变化情况与实际运行情况相符合,可为船舶动力系统的运行优化提供参考。
In order to realize the dynamic characteristic analysis of condenser, adopts modular modeling method, uses Modelica unified physical modeling language and Mworks simulation platform, and develops the model base of thermal system and establishes the condenser simulation model according to the working principle and energy and mass conservation equation of condensate and water supply system. By using the model, the dynamic characteristics of the condenser are analyzed under the condition of the turbine exhaust volume and the step change of circulating cooling water flow rate. The results show that the variation of the internal parameters of the condenser is consistent with the actual operation, which can provide reference for the optimization of the marine power system.
