摘要

基于对某300MW机组一次调频试验

分析了影响其一次调频性能的因素

汽轮机阀门流量函数与实际阀门流量特性不匹配以及机组的运行方式是造成机组一次调频性能不佳的主要原因。采用Matlab/Simulink软件建立了汽轮机及其调节系统模型

以验证试验结果的正确性

并提出了改善机组一次调频性能的建议。

Abstract

On the basis of primary frequency regulation(PFR)on a 300MW unit

the factors affecting performance of the PFR were analyzed.Mismatch between flow function of steam turbine valves and the actual flow characteristics

and the unit's operation mode were considered as the main factors causing poor performance of the unit's PFR.Thus

by employing the Matlab/Simulink software

a model for the steam turbine and its governing system was established to verify the correctness of the conclusion.Furthermore

suggestions for improving the unit's PFR performance were put forward.
