摘要
将功率优化器与太阳能组件结合,可提高光伏阵列在阴影遮挡情况下的发电功率。通过设置不同阴影遮挡,进行模拟实验。在动态阴影遮挡情况下,光伏阵列发电功率有所提高,但增幅不明显;在固定式阴影遮挡情况下,根据遮挡比例的不同,光伏阵列发电功率最高提升17.69%,最低提升-1.40%;在辐照强度由低到高的变化范围内,光伏阵列在不同阴影遮挡条件下的发电功率是从负功率向正功率转变的递增趋势。
The power optimizer combined with the solar module, can increase power generation of the photovohaic array in the condition of shadow. Simulative experiments were carried out according to the condition of different shading under the condition of dynamic shadow, the photovoltaic array can increase power generation, but not too much ; in the condition of fixed shadow, according to different proportion of shadow, the photovohaic array can in- crease maximum power generation 17.69%, the least - 1.40% ; in the range of irradiation intensity changes from low to high, the photovoltaic array module＇ power generation in the condition of different shadow shows increasing tendency from negative to positive.
