Technical Condition Estimation of the Gas Turbine Axial Compressor

Abstract The paper describes an approach for determining the technical state of axial compressor as part a gas turbine unit, based on thermogasdynamic parameters that are measured at operating facility. As criterion condition, it is proposed to use ratio actual efficiency reference in such modes. To do this, enough know temperatures and pressures air inlet outlet compressor. A method selecting modes described some features filtering plant noted. In approach, choice analyzing carried out according value effective power unit. Some results condition which drives centrifugal natural gas, presented. Based analysis degradation criterion, possible determine its predicted value. work can be used create automated systems assessing predicting drive units their facilities. application obtained expands possibilities servicing plants state. adapted applied various purposes, well individual units.
