【 摘 要 】

This paper presents the simulation of photovoltaic (PV) module operation which is created from basic equation of photovoltaic module. The three standard configurations of PV module consisting of series-parallel (SP), bridge-linked (BL), and total cross-tied (TCT) are studied. Nine photovoltaic cells are arranged in a three by three array and the effect of different shaded patterns on electrical generation is predicted. In order to find the optimal configuration of PV module which can generate the highest power during shading and develop the automatic connecting system of each PV cell, the conditions of shading 1 in 9 PV, 2 in 9 PV, 4 in 9 PV, and 6 in 9 PV are simulated. The effectiveness comparison between the case of with and without the automatic array connecting system is tested. When the three standard configurations of PV module are tested during shading, the result found that BL is better than SP by 0.1 - 14 % and TCT is better than SP by 2 - 20 %. It can be concluded that TCT is the best configuration of PV module under shaded conditions.
