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.
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.
