摘　　要：高炉煤气余压透平发电机组(TRT)将高压气体的势能、热能转换成电能。由于高炉煤气的工艺参数不稳定,导致TRT发电保护动作,影响到发电系统的正常运行。通过分析系统组成和保护装置之间的联系,建立了跳闸控制对线路的组合保护,这种组合保护对于局部电网出现问题,可有效地提高发电机的稳定性,有利于提高整体发电效率和系统的稳定。Blast furnace gas residual pressure turbine generator set(TRT) converts heat energy of high pressure gas into electric energy. The unstable process parameters of blast furnace gas lead to the action of TRT power generation protection, which affects the normal operation of power generation system. By analyzing the relationship between the system composition and the protection device, the combined protection of trip control to the line was established. This combined protection can effectively improve the stability of the generator for the problems in the local power grid and the overall power generation efficiency and the stability of the system.
