USABILITY OF CONTROL CHARTS TO MONITOR VARIATION OF QUALITY PARAMETERS IN COAL-FIRED THERMAL POWER PLANTS
Yıl 2020, Cilt 59, Sayı 4, 247 - 253, 01.12.2020Öz
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.

KÖMÜR YAKITLI TERMİK SANTRALLERDE KALİTE PARAMETRELERİNİN DEĞİŞİMİNİN İZLENMESİ İÇİN KONTROL GRAFİKLERİNİN KULLANILABİLİRLİĞİ
Yıl 2020, Cilt 59, Sayı 4, 247 - 253, 01.12.2020Öz
Kömür yakıtlı termik santrallerden elektrik enerjisi üretimi sırasında prosesin verimliliğini değerlendirmek için kalorifik değer ve birim güç değeri en önemli parametrelerdir. Bu değerler periyodik olarak ölçülür ve ölçüm sonuçları üretim sürecinde ortaya çıkabilecek dalgalanmaların temel nedenlerini tespit etmek için izlenir. Bu uygulama mevcut durumda manuel yöntemlerle gerçekleştirildiğinden, hatalı sonuçların elde edilme olasılığı oldukça yüksektir. Bu çalışma, Shewhart ve kümülatif toplam kontrol grafiklerini kullanarak kalite parametrelerinin değişimi üzerindeki proses kontrolünü istatistiksel olarak analiz etmeyi ve olağandışı dalgalanmaların temel nedenlerini tespit etmeyi amaçlamaktadır. Bu amaçla, bu kontrol grafiklerinin kullanılabilirliği Afşin-Elbistan B termik santrali üzerinde test edilmiştir. Sonuç olarak, bu grafikler kullanılarak elektrik enerjisi üretme verimliliğindeki dalgalanmaları ve süreçteki olağandışı değişimler belirlenmiştir. Ayrıca, bu kontrol grafiklerinin geliştirilmesi ve benzer prosesler için de uygulanması önerilmektedir.
