摘要
以引进型600MW机组为例,建立了深度调峰下汽轮机控制参数基准值计算模型。该模型以临界状态下末级流型划分理论为基础,改进了末级压比的数值计算方法;在应用调节级特性曲线上,考虑了调节级温度的变化,使调节级的计算更加准确;以更少迭代的顺序的方法进行计算,在保证计算精度的前提下,提高了计算的速度,适合计算的推广和应用。
To the introduction of 600MW generate sets as an example, establishing a mathematic model which is standard values of control parameter in deep load changing. The model to the critical state at the theory of stage species division, im- proved the numerical method of stage pressure ratio; Application the performance curve, taking into account the temperature changes, the governing stage calculation is more accurate calculation; Sequencing computation reduced the iterative a- mount, it increased computing speed premised on guaranteed accuracy, so it adapt to generalization and application.
