Abstract

The invention provides a high-pressure heater state analysis method based on a genetic simulated annealing algorithm. The method comprises the steps that firstly, data of the operation state of the high-pressure heater are acquired, data loss error processing is conducted on data problems caused by equipment heat, and accidental error processing is conducted on data problems caused by unstable environments or unstable instruments and signals; Main variables influencing power generation operation are found by adopting a main element analysis method, so that the calculation data is reduced, theoperation reaction speed is increased, and representative measuring points are convenient to select; and mining the operation state data of the high-pressure heater based on a genetic annealing algorithm, and finally calculating the membership degree of the high-pressure heater and obtaining the optimal operation state of the high-pressure heater. The FCM clustering mining of the high-pressure heater operation state data is carried out based on the genetic simulated annealing algorithm, and the algorithm not only overcomes the defect that the FCM algorithm is caught in a local optimal solution, but also strengthens the global search function, thereby having better convergence and global search capability.
