research on photovoltaic grid-connected inverter with maximum power point tracking 采用最大功率点跟踪的光伏并网逆变器研究
research on maximum power point tracking control based on a dsp-controlled grid-connected photovoltaic inverter 双支路光伏最大功率跟踪的并网逆变器的研制
mppt ( maximum power point tracking ) is one of the most important and well-known problem for all pv systems mppt(最大功率点跟踪)是光伏系统中经常遇见的问题。
the functions which pv system controllers need to have are discussed in theory too, such as controlling of charging and discharging, adaptation of orientation and position of solar cell, maximum power point tracking ( mppt ) 本文还从理论上探讨了光伏系统控制器应具有的功能:对蓄电池充放电的控制,对太阳方位和高度的跟踪,对太阳能电池最大功率点的跟踪。
the paper proposes a method that combines " mass law "-- acceptable charging current with technology of solar photovoltaic array's maximum power point tracking in stand-alone photovoltaic system . it realizes a efficient charging management of vrla storage battery . and fuzzy hierarchical control technology is applied to the depolarization control 提出在独立光伏系统中采用“马斯定律”可接受充电电流和太阳能光伏阵列最大功率跟踪相结合的方法,对系统中vrla蓄电池进行高效充电管理,并采用模糊递阶控制技术来实现去极化控制,实现系统能量最大利用。
