汽轮机循环水系统的稳态仿真数学建模

汽轮机循环水系统是一个冷水与高温水蒸气的热交换系统，其水温与水压的机理数学模型十分复杂，不适用于计算机实时仿真系统。作者利用电厂实测数据，通过一种超曲面拟合的方法，建立了该系统水温与水压的仿真数学模型，该模型计算量较小。仿真结果验证了这种拟合建模方法具有较高的精确度。

Mathematical Modeling for the Simulation of the Circulating Water System of a Steam Turbine

The circulating water system of a steam turbine represents a heat exchange system of cooling water and high temperature steam. The mathematical model based on the mechanism of the cooling water and water pressure is very complicated and not suited for a computer based real time simulation system. By the use of the measured data of a power plant and with the help of a hyper curvature fitting method set up was a mathematical model for the simulation of the water temperature and water pressure of the circulating water system. The recommended model involves a relatively small computation load and features a high precision as certified by the simulation results.
