Problems solved by technology

[0003]At present, the optimization of gas-steam combined cycle units usually only involves simple performance test calculations, and requires a lot of time and preparation work to complete field tests. Data analysis of the operating status and indicators of the unit only focuses on the test performance of the unit and does not have the significance of real-time monitoring of the unit

In addition, the analysis and calculation of the unit consumption difference only stays in the theoretical calculation stage, and has not been applied in the actual operation of the unit, nor can it effectively guide the economic operation of the unit
