本文在实验基础上用频率法研究了各种不同燃气轮机装置作为复杂调节对象的特点。主要蓄能器(回热器,压气机轴轮子,中间容积和气遇热交换过程)对不同装置动态特性的影响,这些影响通过实际微分环节或是积分-微分环节表述出来。在结构分析的基础上提出了改进调节过程的调节系统原则方案,对单轴或是BB型双轴具有回热器的装置建议用回热器后空气温度作为附加冲量,而对分轴或是空气流量有大幅度变化的装置建议用压气机轴的转速作为附加冲量。
Based on the experiment, this paper studies the characteristics of various gas turbine devices as complex adjustment objects by frequency method. The impact of the main accumulators (regenerator, compressor shaft wheel, intermediate volume, and gas heat exchange process) on the dynamic characteristics of different devices is expressed by the actual differential or integral-differential steps. On the basis of the structural analysis, the principle scheme of the adjusting system to improve the adjusting process is put forward. It is suggested to use the back air temperature of the regenerator as the additional impulse to the uniaxial or BB type biaxial device with regenerator, The device with a large change in air flow suggests using the speed of the compressor shaft as an additional impulse.
