Abstract
يتطرق البحث الى تصميم منظومة قدرة شمسية ومحاكاتها مكونة من لوح شمسي نوع KC200GT ، محول Boost ذي دائرة مغلقة وعاكس ثلاثي الطور باستخدام برنامج Matlab/Simulink . تم التطرق الى المعادلات الرياضية الخاصة بتصميم اللوح الشمسي. تم اختبار الخصائص الكهربائية للوح عند القيم 1000 للاشعاع الضوئي و 25 درجة مئوية لدرجة حرارة المحيط . يربط المسيطر PI مع المحول بوصفه دائرة تغذية عكسية للحصول على فولتية خرج مستقرة عن طريق تقليل التذبذبات في الفولتية لشحن بطارية تربط على خرج المحول . تم استخدام طريقتين (Particle Swarm Optimization و ( Zeigler-Nichols لضبط مسيطر PI لغرض تحسين الاداء الكلي للمنظومة. تم استخدام تقنية SPWM للحصول على موجة نقية ثلاثية الطورباقل تشويه ، وتم الحصول على قيم فولتية وتيار خرج المنظومة هي و ، و قيمة ال THD هي 4.20% .
Highlights
Nowadays, photovoltaic (PV) panels are widely used to convert the solar radiation into electricity
The tuning values of the controller are tested in level control system. They prove that Particle Swarm Optimization (PSO)-Proportional Integral (PI) controller yield good results than gain scheduling method.This paper presents the design and Simulation of a PV power system consist of solar panel type KC200GT, DC-DC boost converter for interface between PV panel and 3-phase inverter
A complete Matlab/Simulink of PV module and closed loop Boost converter connected to 3phase inverter are carried
Summary
Photovoltaic (PV) panels are widely used to convert the solar radiation into electricity. Achari [3] presented model of a buck-boost converter for Photo-Voltaic applications They used Perturbation and Observation (P&O) method to achieve maximum power point. SPWM technique is used to control the operation of inverter, and PSIM (a simulation tool designed for power electronics and dynamic systems) software is used for converter topology. The tuning values of the controller are tested in level control system They prove that PSO-PI controller yield good results than gain scheduling method.This paper presents the design and Simulation of a PV power system consist of solar panel type KC200GT, DC-DC boost converter for interface between PV panel and 3-phase inverter. The PI controller is used to regulate output voltage of Boost converter to get the fast transient response by adjusting the value of proportional gain ( ܭ ) and integral gain ( ܭ ) .
