摘要
当燃气轮机的燃烧室产生燃烧不稳定性时,往往会发生跳机事件,降低了机组运行效率。通过调节透平排气温度和值班气体流量,可以避免因燃烧不稳定性所引起的跳机事件。通过在不同工况和不同的限值条件下,对SMCO和SMCP两种控制器的建模与仿真,验证了该燃气轮机燃烧控制算法的可行性和有效性。SMCO与SMCP控制器能有效提高燃气轮机燃烧的稳定性。
When the combustion of gas turbine becomes instable, it will accompany with the occurrence of trip event, therefore cause the lower efficiency of unit. But it could be avoided by modulating the outlet temperature of gas turbine and the flow of pilot gas. The aim of this suhjeet is to verify the feasibility and effectiveness of the combustion control algorithm of gas turbine through modeling and simulating of SMCO and SMCP in different operating conditions with various limit. It finally shows that SMCO and SMCP are able to improve the combustion stability of gas turbines.
