Abstract:

In this paper, the efficiency monitoring of steam turbine and compressors, the fouling of steam turbine and the judgment of fouling tendency, and the preventive maintenance and repairs are studied. By establishing monitoring and fault diagnosis systems for the thermal performance of steam turbine and its compressor unit, the performance prediction model was built for the compressor unit, and the thermal parameter monitoring and performance prediction of the compressor unit were carried out. Meanwhile, an on-line monitoring system was developed for the thermal performance of compressor unit to optimize the operation of compressors and steam turbine.

Key words: turbine driven compressor unit, on-line performance monitoring, development
