FV Panel Temizliği için Doğrusal Motor ve Mekanizma Tasarımı

Fotovoltaik (FV) sistemlerin ilk kurulum maliyeti yüksek iken genel sistem verimliliği düşüktür. Bundan dolayı kurulan sistemin maksimum verimlilik ile çalışması hedeflenmektedir. Verimliliği etkileyen unsurlardan biri de panel yüzeyinin toz/kar/kirlenme gibi çeşitli nedenlerle kaplanmasıdır. FV panele gelen ışınların geçmesine engel olan bu durumlarının giderilmesi için bir süpürücü mekanizma tasarlanmış ve tahrik elmanı olarak kullanmak üzere Doğrusal Fırcasız Dogru Akım Motoru (FDAM)tasarımı yapılmıştır. Doğrusal FDAM’nin Sonlu Elamanlar Yöntemi (SEY) ile magnetostatik ve statik stres analizleri yapılmış ve tasarıma ait sonuçlar elde edilmiştir. Sonuçlar tasarlanan Doğrusal FDAM sistem için gerekli kuvveti üretebildiğini göstermiştir. Ayrıca sistem için öngörülen enerji tüketim hesabı yapılmıştır. Doğrusal FDAM’nin süpürücü mekanizması ile yapacacağı enerji tüketiminin, sistem verimliliğine etkisinin yanında çok düşük kaldığı sonucuna ulaşılmıştır.

Lineer Motor and Mechanism Design for PV Panel Cleaning

Altough the initial setup cost of photovoltaic systems is high, overall system efficiency is low. Therefore,the established system is aimed to work with maximum efficiency. One of the factors affectingefficiency is that the panel surface is covered for various reasons such as dust / snow / pollution. A sweeping mechanism has been designed to eliminate these situations that prevent the passage of therays coming to the PV panel, and a Linear Brushless Direct Current Motor (BLDC) motor has beendesigned to be used as a drive element. Magnetostatic and static stress analyzes of Linear BLDC weremade with Finite Elements Method (FEM) and design results were obtained. The results showed thatthe designed Linear BLDC motor is capable of generating the power required for the system In addition,the energy consumption calculation foreseen for the system has been made. It has been concluded thatthe energy consumption of Linear BLDC with its sweeping mechanism remains very low in addition toits effect on system efficiency.
