الكلمات المفتاحية:
لتبريد الشمسي، كفاءة المحطة، الطاقة المتجددة، تقليل التلوث، إنتاجية الكهرباءالملخص
تتعرض محطة بنغازي الشمالية للطاقة لتقلبات كبيرة في درجة حرارة الهواء المحيط ومياه البحر على مدار السنة، مما يؤثر سلبًا على الأداء والطاقة المنتجة، وبالتالي زيادة معدلات انبعاث ثاني أكسيد الكربون. إن استقرار درجة حرارة الهواء الداخل والتحكم في درجة حرارة مياه التبريد عند المدخل في ظروف التصميم يعزز ويحافظ على الأداء والكفاءة طوال العام.
تم اعتماد نظام دورة امتصاصية للماء-بروميد الليثيوم أحادية التأثير مدعومة بمجمع شمسي بارابوليك تروغ، ولضمان التشغيل الفعال خلال فترات عدم سطوع الشمس، تم إدخال خزان تخزين حراري معزول لتخزين الطاقة الحرارية للوسط العامل، مع تزويد مساعد بالطاقة الحرارية القادمة من غازات العادم التابعة لنظام HRSG لتعويض أي انخفاض في درجة الحرارة داخل الخزان، على ألا تقل عن 80 درجة مئوية لضمان فعالية تشغيل نظام التبريد.
أظهرت نتائج النموذج تحسن الكفاءة الإجمالية بنسبة 3.635٪ وزيادة الطاقة المنتجة بنسبة 12.18٪، مع تقليل انبعاثات الغازات الدفيئة بنسبة 3.537٪. كما زاد الإنتاج السنوي للكهرباء بنسبة 9.767٪ و7.728٪ لمحطة توربين الغاز المستقلة والدورة المركبة على التوالي، وزاد صافي إنتاج الكهرباء بمقدار 141,358,530 ك.و/سنة، مما يمكن أن يوفر 14,135,853 دولارًا سنويًا. على الرغم من أن التكلفة الرأسمالية مرتفعة نسبيًا، فإن فترة الاسترداد تبلغ 1.48 سنة بسعر بيع للطاقة 0.1$/ك.و/س. وبلغ عامل المساهمة السنوية للنظام الشمسي البارابوليك تروغ 91.896٪ خلال فترات الشمس الساطعة
