EVALUATION OF THE STRUCTURE AND ENERGY GENERATION OF A INTEGRATED SOLAR COMBINED CYCLE POWER PLANT

Öz

Population growth, technological advancements, and growing living standards have all contributed to a rise in energy demand. Due to the fact that fossil fuels are not sustainable, renewable energy sources have emerged as a viable alternative. The need for development is growing all the time. In this study, a combined cycle power plant in which solar energy is integrated is discussed. For this purpose, in the designed model calculations; for solar energy data, the values of Emirgazi district of Konya province were used. The solar-field warms a thermal oil (Therminol VP-1) that is then circulated through a sequence of shell and tube heat exchangers that preheat feedwater, create steam, and superheat steam. The solar generator gets warmed feedwater from the HRSG and returns superheated steam, which is combined with HP steam when it exits the first superheater.As a result of model calculations; The net electricity efficiency (LHV) of the power plant was 56% and the heat recovery steam generator 89%.

ENTEGRE GÜNEŞ KOMBİNE ÇEVRİM SANTRALİNİN YAPISI VE ENERJİ ÜRETİMİNİN DEĞERLENDİRİLMESİ

Öz

Günümüzde nüfus artışı, teknolojik gelişmeler ve artan yaşam standartları, enerji talebindeki artışa katkıda bulunmaktadır. Fosil yakıtların sürdürülebilir bir kaynak olmaması nedeniyle yenilenebilir enerji kaynakları uygulanabilir bir alternatif olarak ortaya çıkmaktadır. Bu çalışmada güneş enerjisinin entegre edildiği bir kombine çevrim santrali ele alınmıştır. Bu amaçla tasarlanan model hesaplamalarında; güneş enerjisi verileri için Konya ili Emirgazi ilçesinin değerleri kullanılmıştır. Model santralde, parabolik oluklu güneş alanı, besleme suyunu önceden ısıtan, buhar üreten bir dizi ve borulu ısı eşanjörlerinden pompalanan bir termal yağı (Therminol VP1) ısıtmaktadır. Model hesaplamaları sonucunda; santralin net elektrik verimi (LHV) % 56 ve ısı geri kazanımlı buhar jeneratörünün verimi de % 89 bulunmuştur.
