某型三轴燃气轮机发电性能仿真研究

摘要

According to the performance of gas turbine power generation, a simulation model was built based on Matlab/Simulink soft-ware.A conventional PID fuel control and deflated air control were selected as control structure, while power load change cases were simulated.Focus area were the load change influenced on the changes and dynamic response of speed, after low-pressure turbine tem-perature and fuel gas than.%针对某型三轴燃气轮机的发电性能，基于Matlab／Simulink仿真工具构建燃气轮机模型。控制方式选用常规PID燃油控制和放气控制，对带电力负载中常见的负荷变化过程进行仿真研究。重点关注负荷变化对转速、低压涡轮后温度和油气比的影响及动态响应过程。
