Gas Turbine Compressors are now wildly used on long-distance natural gas pipelines.A system named compressor equipment health management was developed and built to ensure the economic, efficient operation of gas turbine compressor with high reliability. With the gas turbine analysis program of this system, engineers can grasp the real-time situations of gas turbine compressors, diagnosis and solve those problems occurred in operation timely, keep the gas turbine compressors operating at high efficiency by monitoring and reducing the efficiency degradation.This system calculates, analyzes and statistics the compressor efficiency which is compared to the actual operating efficiency to recognize the compressor status.The life prediction calculations of hot section engine components were performed by life module in order to realize the on-condition maintenance of gas turbine and optimize maintenance cycles.Those appli-cation results indicate that the operating efficiency of gas turbine compressor has been improved and the maintenance cost of gas turbine has been reduced after applying this system.
