The performance analysis and diagnosis system of gas-steam combined cycle unit based on big data is developed. The system uses big data technology to conduct parameter integration and correlation analysis for historical and real-time operation data of the unit. The potential value of the data is used to monitor the unit status and guide the unit to optimize operation. Moreover
a real-time economic calculation analysis and state evaluation model for gas-steam combined cycle unit operation is established. The main functions of the system include performance calculation
performance analysis and diagnosis
performance optimization and equipment status analysis
which can guide the optimal operation of the unit
improve the operation economy of the unit
and provide equipment status basis for condition-based maintenance of the unit.
