Özet
During the production of electrical energy from coal-fired thermal power plants, calorific and unit
power values are the most important indicators for evaluating the productivity of the process.
These values are measured periodically, and the resulting measurements are monitored to detect
root causes of variation that may occur in production process. As this application is currently
performed by manual methods, the probability of obtaining incorrect results is quite high. This
study aims to statistically analyze process control on the variation of quality parameters and
detect root causes of unusual variations using Shewhart and cumulative sum control charts. For
this purpose, the usability of these control charts was tested on Afşin-Elbistan B thermal power
plant. As a result, these charts identified fluctuations in the efficiency of generating electrical
energy and unusual variations in the process. Furthermore, it is recommended that these control
charts could be developed and applied in similar type of process
