摘要: 摘要: 针对联合循环中燃气轮机变工况运行时排气温度控制这一重要环节,以某型联合循环燃气轮机为研究对象,介绍了燃气轮机进口可转导叶(IGV)温度控制的作用和原理.在变负荷和环境温度扰动2种变工况的情况下,对比分析了纯反馈、单前馈反馈和双前馈反馈3种不同IGV温度控制策略的燃气轮机性能参数动态响应过程.结果表明:相比于其他控制策略,采用负荷和环境温度的双变量前馈反馈控制策略在变负荷和环境温度扰动时具有更好的控制效果.

Abstract: Abstract: In view of the importance of exhaust temperature of gas turbine to the operation of a power unit under offdesign condition, the function and principles of temperature control of inlet guide vane (IGV) were introduced by taking the gas turbine of a combine cycle as a study object. With the conditions of load and ambient temperature changed, the dynamic response process of thermodynamic parameters of gas turbine was compared and analyzed under three different control strategies, ie., pure feedback control, feedforwardfeedback control and double feedforwardfeedback control. The results show that the control characteristic of double feedforwardfeedback control strategy is better than that of other control strategies.
