摘要
从我国大型石化厂发展的需要，阐述了开展蒸汽系统设计工作的必要性。叙述了按照编制通用软件要求构成的通用蒸汽系统和自动建模的方法。在部件模型部分叙述了汽轮机的模型，它是变工况性能模型，不仅可提高蒸汽系统热平衡计算的精度，且使编制的软件能用于生产工况变化后蒸汽系统的热平衡。系统的优化以综合能耗最低为目标函数，以有效地降低系统的能耗。使用结果表明，本文编制的通用优化软件是成功的。
The necessity of optimization of steam systems is described in order to develop largescale petrochemical plants in China.A generalized structure of steam systems and the auto-modelling technique are proposed, complying with the requirements of compiling a general-purpose computer program.By using the steam turbine models to deal with the off-design performance,the heat balance of the steam system can be modelled for various operation conditions.The objective function of optimization is the lowest total energy consumption. Actual running of the program shows that energy consumption can be decreased effectively.
