| 摘 要： | 在建立燃气轮机仿真模型时,对压气机特性曲线的处理非常关键,直接影响整机的计算精度。本文根据压气机特性曲线的形状相近性及其形状和位置渐进变化的规律,将特性曲线分成高转速段与低转速段,然后做分段二步一元拟合来构成压气机特性参数的函数关系式,并以实例详细说明。分析表明该拟合方法具有较高的精度,能满足燃气轮机特性计算的需要,且该方法原理简单,操作方便,具有一定的实用价值。

| Abstract: | It is very important of the treatment to compressor characteristic curve of gas turbine while building the simulation model of gas turbine,which impact on the simulation precision directly.The characteristic curve is divided into low speed and high speed section according to the shape proximity and the change regularity of shape and position of the compressor characteristic curves.Then the compressor characteristic curve is fitted by two-step one variable fitting method,to construct the function equation of the compressor characteristic parameter,and is explained with detailed examples.Analysis proves the high precision of this method which is competent for the calculation of gas turbine performance,meanwhile,this method is simple and easy to operate and have some practical value. |
