چکیده
استفاده از انرژی خورشیدی در چرخه‌های توربین گازی به‌عنوان روشی نوین، می‌تواند بازده سیستم را افزایش داده و مصرف سوخت فسیلی را کاهش دهد. در این مطالعه، یک نیروگاه توربین گازی-خورشیدی تک‌محور، تحت شرایط طراحی و خارج از طراحی شبیه‌سازی و از منظر انرژی و اگزرژی تحلیل شده است. مدل‌سازی شامل کمپرسور، توربین، محفظه احتراق، مبدل حرارتی و گیرنده خورشیدی انجام شد و اثر پارامترهایی نظیر نسبت فشار کمپرسور، دمای ورودی توربین و تابش خورشیدی بررسی گردید. نتایج نشان می‌دهد که استفاده از انرژی خورشیدی موجب کاهش مصرف سوخت و کاهش نابودی اگزرژی در محفظه احتراق می‌شود. نتایج حالت خارج از طراحی نشان می‌دهد که تغییر دور و تابش خورشیدی، تأثیر قابل‌توجهی بر توان، مصرف سوخت و بازده سیستم دارد. افزایش دور کمپرسور موجب افزایش جریان جرمی هوا و نیاز به سوخت بیشتر برای حفظ نسبت هوا به سوخت می‌شود که توان خروجی را بالا می‌برد، اما مصرف سوخت نیز افزایش‌یافته و بازده حرارتی کاهش می‌یابد.

چکیده English

The integration of solar energy into gas turbine cycles, as an emerging approach, can enhance system efficiency while reducing fossil fuel consumption. In this study, a single-shaft solar-assisted gas turbine power plant is simulated under both design-point and off-design conditions and analyzed from energy and exergy perspectives. The model incorporates a compressor, turbine, combustion chamber, heat exchanger and solar receiver. The effects of key parameters, including compressor pressure ratio, turbine inlet temperature, and solar irradiance, are systematically investigated. The results demonstrate that the utilization of solar energy significantly reduces fuel consumption and decreases exergy destruction in the combustion chamber. Off-design analyses indicate that variations in rotational speed and solar irradiance have a substantial impact on power output, fuel consumption, and overall system efficiency. An increase in compressor speed leads to a higher air mass flow rate and consequently requires a greater fuel input to maintain an appropriate air–fuel ratio. Although this results in higher power output, it is accompanied by increased fuel consumption and a reduction in thermal efficiency. Therefore, while solar integration primarily improves efficiency and reduces primary energy consumption, off-design operation reveals important trade-offs between power augmentation, efficiency degradation, and fuel usage.
