为了有效减少管道燃驱压缩机组运行机械故障,保障平稳运行,需要开展燃驱压缩机组性能监测研究。通过对近年来发生的燃气轮机压气机叶片脱落及损坏、透平静叶烧蚀、喷嘴烧蚀等典型故障进行分析,开展了机组测点布置、性能监测参数的研究,设计了燃驱压缩机组性能监测计算核心架构,开发了性能监测系统。该系统主要功能包括故障预警、性能参数趋势显示、性能衰减判断等,根据对燃气轮机运行状态参数的监测,分析运行趋势和性能衰减情况,结合现场实际运行状况和维检修数据,从而判断机组的健康状况。燃驱压缩机组性能监测系统的现场应用效果明显,可以减少机组故障停机、优化维检修周期、节约维检修成本。
In order to reduce the mechanical faults effectively during the operation of turbine-driven compressor set and ensure its smooth operation, it is necessary to study the performance monitoring of turbine-driven compressor set. In this paper, the typical failures of gas turbines in recent years were analyzed, including compressor blade shedding ＆ damage, turbine blade ablation and nozzle ablation. Then, the measuring point arrangement and the performance monitoring parameters were investigated. Finally, the core calculation framework for performance monitoring of turbine-driven compressor set was designed, and the performance monitoring system was developed. The main functions of this system include fault pre-warning, performance parameter trend display, performance attenuation discrimination and so on. The health status of compressor set is judged based on the operation state parameter monitoring of gas turbine, the operation trend and the performance attenuation, combined with the on-site actual operation situations and maintenance ＆ repair data. The field application effects of this performance monitoring system for turbine-driven compressor sets are remarkable with reduced compressor unit scram, optimized maintenance ＆ repair period and economic maintenance ＆ repair cost.
