IRAK’TA PARABOLİK OLUK TİPİ GÜNEŞ KOLLEKTÖRLÜ HİBRİT BUHAR SANTRALİNİN TERMODİNAMİK ANALİZİ VE SİMÜLASYONU
Öz
Pek çok ülkede elektrik üretimi çevre için zararlı olmalarına rağmen, büyük oranda fosil yakıtla çalışan termik santrallarla yapılmaktadır. Güneş enerjisinin bu halihazırdaki termik santrallarla entege edilmesi sureti ile hibrit şeklilde enerji üretimi birçok açıdan oldukça akılcı ve ekonomiktir. Bu çalışmada parabolik oluk tipi güneş kollektörlü hibrit buhar santralinin termodinamik analizi yapılmıştır. Tasarım süreci, solar kollektörlerde kullanılacak sıvının seçimini, kollektör sahasının ölçüleri ve kullanılacak kollektör sayısının tayinini, kollektör ve buhar santralını bağlayan ısı eşanjörünün ön tasarımını ve son olarak da hibrit sistemin termal analizini içermektedir. Nümerik modelin doğrulanmasının ardından buhar santralı ve hibrit santralın simülasyonları yapılmış, güç artışı, verim iyileşmesi, yakıt tasarrufu ve çevresel etkiler incelenmiştir. Ayrıca güneş kollektörü sahasında üretilebilecek ekstra enerji miktarları hesaplanmış ve faydalı enerji, ısı kaybı faktörü, solar akışkan sıcaklıkları, cam ve soğurucu boru sıcaklıkları hesaplanmış ve birbirleri ile kıyaslanmıştır. Son olarak basit ekonomik analiz yapılmış, seviyelendirilmiş enerji maliyeti (LCOE) hesaplanmış ve hibrit santralın ekonomik açıdan da avantajlı olduğuna dikkat çekilmiştir. Çalışma, hibrit sistemin daha güvenilir, daha yüksek verimli olduğuna dikkat çekmektedir. Verim artışı, güç artışı, yakıt tasarrufu ve azalan su kullanımı miktarları hesaplanmış ve farklı durumlar için birbiri ile kıyaslanmıştır. Güneş sahasının santrala entegrasyonun da bu parametreler üstünde oldukça önemli bir rol oynadığı ispatlanmıştır. |

THERMODYNAMIC ANALYSIS AND SIMULATION OF STEAM TURBINE POWER PLANT HYBRID WITH PARABOLIC TROUGH COLLECTORS; A STUDY IN IRAQ
Öz
Fossil
fuel thermal power plants are major investments for electricity production
despite of their environmental drawbacks. Using solar energy in a hybrid manner
with these power plants a sensible and an economical choice for advanced power
generation. In this study, thermodynamic
analysis and simulation of a steam turbine power plant hybrid with parabolic
trough solar collector field is done. Design process includes selection of heat
transfer fluid (HTF), determination of the required solar power, orientation
and sizing of the solar field, preliminary design of the solar heat exchanger
(HEX) and thermodynamic analysis of the hybrid plant. After verification of
computational model, simulations of steam power plant and hybrid power plant
are done and results for increasing output electricity and saving fuel oil are
studied considering the efficiency improvement and the environmental effects.
Important solar field parameters like HTF, glass and absorber temperatures,
heat loss coefficients and output power of the collector field are simulated
and discussed. Finally, a simple economic analysis is done using levelized cost
of energy method (LCOE) which showed that hybridization is economically
sound. The study also suggests that,
hybridization is a sensible choice for increasing efficiency and output power,
decreasing use of fossil fuels, thus environment problems. The orientation of
the hybrid connection plays an important role on these parameters.
