针对燃气轮机启动特性的研究中较少考虑关键辅助系统的影响，以某型号F级燃气轮机为研究对象，建立了一个包括本体系统、进排气系统、冷却空气、防喘放风、静态变频器和阀门执行机构等在内的精细化启动过程仿真模型。对该模型进行设计点工况验证，最大误差能控制在0.15%以内。通过dSPACE系统与实际电厂控制逻辑相连，构建半物理联合仿真平台。对燃机模型在启动瞬态过程的特性进行仿真分析，并与实际电厂运行数据对比，最大偏差发生在刚点火之后，其中转速偏差为11 r/min，压气机出口压力偏差为6 kPa透平排气温度偏差为9 ℃。

Since the research on the characteristics of the gas turbine startup process lack considerations of key auxiliary systems,with an Fclass gas turbine as the research object,a detailed model of the gas turbine startup process including intake and exhaust system,cooling air,antisurge ventilation,static frequency converter system and valve actuator has been built.The gas turbine model is verified under design point and the error can be controlled within 0.15%.A semiphysical cosimulation platform through the dSPACE system and the actual power plant control logic has also been built.Based on the platform,the simulation results of the gas turbine speed,compressor outlet pressure and turbine exhaust temperature during the startup process show that the maximum error to the actual power plant operating data happens just after the ignition.The maximum error is about 11 r/min.6 kPa and 9 ℃ respectively.
