| titleOfInvention | Steam turbine pitch rating curve discrimination method based on DCS data minings |
| abstract | The invention discloses a kind of method that steam turbine pitch rating curve is recognized by DCS data mining technologies：A, the selection sampled point related to pitch traffic characteristics analysis, obtain DCS data；B, DCS data are divided into data mining object, audit exceptional value therein, and calculate average, extreme difference and the slope of each sampled point of data mining object；C, dimension reduction is carried out to the extreme difference and slope of each data mining object using PCA；D, the running status of pitch is clustered using density-based algorithms DBSCAN；E, data mining object is adapted to nominal margin parameter using Variable Conditions of Steam Turbine characteristic and one, two class fair curves；F, object is excavated using Moving Least fitting data obtaining Steam Turbine pitch rating curve；The present invention can recognize rating curve of the steam turbine pitch under nominal margin parameter, can be used for attitude conirol and optimization, to ensure that generating set is safe and stable, economical operation. |
