Potential Assessment of PTTSTP Plant in Bilecik

Abstract

In this study, Parabolic Trough Type Solar Thermal Power (PTTSTPP) Plant design which in accordance with Organic Rankine Cycle has been done considering Bilecik conditions. The system consists of Solar field (SF), Thermal Energy Storage (TES) and Power Block (PB). R-141b was used as the working fluid in the power block, Therminol VP-1 was used in the solar field and Molten-salt was used as the thermal energy storage material. Different parameters have been taken into consideration in the design of the power plant. These designs were evaluated according to the first and second laws of thermodynamics and it was determined that power could be produced between 132 MWh -169 MWh and the system efficiency ranged between 19.36% - 24.73. In addition, Finally, the Net Present Value (NPV) method was used in the economic analysis of the system. The useful life of the system is determined as 20 years and the cost of the system is calculated as 7.924.241.849.09 TL and it is determined that this system is suitable for investment.

Bilecik için POTGTG Santralinin Potansiyel Değerlendirilmesi

Abstract

Bu çalışmada, Bilecik şartları göz önüne alınarak Organik Rankine Çevrimi (ORC) esasına göre çalışan Parabolik Oluk Tipi Güneş Termal Güç (POTGTG) Santrali tasarımı yapılmıştır. Sistem, Güneş alanı (GA), Termal Enerji Depolama (TED) sistemin ve Güç bloğundan (GB) oluşmaktadır. Güç bloğunda çalışma akışkanı olarak R-141b, güneş alanında Therminol VP-1 ve termal enerji depolama malzemesi olarak Eriyik tuz kullanılmıştır. Santral tasarımında farklı parametreler dikkate alınmıştır buna göre bu tasarımlar termodinamiğin birinci ve ikinci yasasına göre değerlendirilmiş olup sistemden 132 MWh -169 MWh arasında güç üretilebileceği, sistem veriminin %19,36 - %24,73 arasında değiştiği belirlenmiştir. Son olarak sistemin ekonomik analizinde Net Bugünkü Değer (NBD) yöntemi kullanılmıştır. Sistemin faydalı ömrü 20 yıl olarak belirlenmiş olup sistem maliyeti 7.924.241.849,09 TL olarak hesaplanmıştır ve bu sistemin yatırım için uygun olduğu belirlenmiştir.
