Evaluation methods of the technical condition and forecasting of indicators of the gas-compressor plant GTK-25IR operation
The technological model of the gas-turbine plant as a part of the gas-compressor plant should give a chance to predict the parameters of work of the gas-turbine plant at the set mode taking into account the actual technical state of the gas-turbine plant and technological restrictions specified by the manufacturer and the project of the compressor shop. A generalizing indicator of technological restrictions on the gas-turbine plant is the size of the available capacity. A generalizing indicator of overall performance of the gas-turbine plant is the effective efficiency. Their current values are simply determined by the parameters of work of the gas-compressor plant. However for the considered type of the gas-compressor plant the formulas carrying to the standard working conditions aren’t applicable. Therefore there is a problem of difficulty to assess the technical condition and forecast the size of the available capacity and effective efficiency at the change of the technical condition, the operating mode and external conditions. This research is devoted to the development of the methods directed on the solution of this problem.
