research on maximum power point tracking control based on a dsp-controlled grid-connected photovoltaic inverter 雙支路光伏最大功率跟蹤的并網(wǎng)逆變器的研制
mppt ( maximum power point tracking ) is one of the most important and well-known problem for all pv systems mppt(最大功率點跟蹤)是光伏系統(tǒng)中經(jīng)常遇見的問題。
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 ) 本文還從理論上探討了光伏系統(tǒng)控制器應具有的功能:對蓄電池充放電的控制,對太陽方位和高度的跟蹤,對太陽能電池最大功率點的跟蹤。
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 提出在獨立光伏系統(tǒng)中采用“馬斯定律”可接受充電電流和太陽能光伏陣列最大功率跟蹤相結(jié)合的方法,對系統(tǒng)中vrla蓄電池進行高效充電管理,并采用模糊遞階控制技術來實現(xiàn)去極化控制,實現(xiàn)系統(tǒng)能量最大利用。
