摘要

在燃气轮机制造国产化程度不断提高的背景下，部分燃气轮机部件偏离了原设计值，但控制参数没有进行相应调整，导致燃气轮机燃油阀在加速过程中出现连续振动现象。以9E-DLN(干式低氮氧化物)燃气轮机典型启动过程算法为基础，根据GE公司的控制方法，研究了FSR(燃油冲程基准)的计算准则。通过建立燃气燃油阀传递函数控制模型，使燃油系统的响应随控制参数的变化而变化。最后，给出了控制参数优化的仿真结果，并对控制参数的优化提出了建议。

Root Cause Analysis of SRV Oscillation during Gas Turbine Start-up Acceleration

Under the background of the continuous improvement of gas turbine manufacturing localization, some gas turbine components deviate from the original design value, but the control parameters are not adjusted accordingly, which leads to the phenomenon of continuous vibration of gas turbine fuel valve in the process of speed-up. Basing on algorithm of typical start-up processing of 9E-DLN (Dry Low NOx) gas turbine, FSR (Fuel Stroke Reference) calculation criterion is studied according to the control method of GE Company. Through the establishment of gas fuel valve transfer function control model, the response of fuel system will be changed as control parameters vary. Finally, simulation results are provided to optimize the control parameters and provide some suggestions for the optimization of the control parameters.
