燃气轮机的数学模及数字模拟

本文提供了一个在部件特性的基础上，建立燃气轮机的数学模型与计算机程序。功能有三：可计算不同进气条件下，自慢车至最大工况之间任意点的静态特性；可计算相应条件下，线性动态模型的系数矩阵（或动态参数）；可进行小扰动及大扰动（加、减速过程）下的动态数字模拟。即提供了一台燃气轮机的静、动态数字模拟器，为燃气轮机及其自动控制系统的设计、使用与改型提供了有力的工具。

MATHMATICAL MODELING AND DIGITAL SIMULATION OF GAS TURBINE ENGINES

A mathematical modeling and digital simulation technique of gas turbines based upon the component characteristics is presented. The computer program of the engine model posses three main functions: to calculate the steady state characteristics of the engine from idle to maximum power under different intake ambient conditions; to calculate the coefficient matrices (or dynamical parameters) of the linear dynamical model under the corresponding calculating points; and to simulate the transient responses of the engine under small perturbations or large perturbations acceleration from idle to maximum power or deceleration from maximum to idle power digitally. However, a steady and dynamical simulator of gas turbine engine is presented for predicating the performance, estimating the affecting factors of the engine and selecting the appropriate parameters of the engine and its control system in design or actual operation.
