宽输入电压范围MPPT控制算法

电力电子技术 2014年第9期48卷 7-9页

作者：汤宪宇刘江程善美华中科技大学自动化学院湖北武汉430074

针对单相双级式光伏并网逆变器中,当光伏输入电压高于直流母线时最大功率点跟踪(MPPT)控制算法失效的问题,提出宽输入电压范围MPPT控制算法。该算法在光伏输入电压低于直流母线电压的情况下扰动Boost电路的占空比;在高于直流母线电压的... 详细信息

针对单相双级式光伏并网逆变器中,当光伏输入电压高于直流母线时最大功率点跟踪(MPPT)控制算法失效的问题,提出宽输入电压范围MPPT控制算法。该算法在光伏输入电压低于直流母线电压的情况下扰动Boost电路的占空比;在高于直流母线电压的情况下扰动母线参考电压,并在临界电压附近设置滞环以避免控制算法频繁切换。该算法很好地解决了低电压和高电压情况下MPPT的准确性问题。通过Matlab/Simulink仿真和样机试验,验证了该算法具有跟踪电压范围宽、动态性能好、稳定可靠的优点。

唐诗《送李使君赴泉州诗》描绘了"泉州"外国商人云集,各国使臣从这里上岸"执玉"朝贡的场景,被公认为唐代福建海外贸易兴盛的经典文字。此诗呈现的是初唐岭南道辖古泉州边地"云山"自然、人文和贸易景况。绥安县故地云霄古称安仁,位于古泉州与广州中途,虽地处海陬,但水陆交通方便,是官宦过往、商旅来回和贬官流放之必经。此地开发起始于汉代,发展于晋朝,到初唐形成商肆集中的滨海自由边贸,吸引各地商旅和远方番邦前来交易,由此助发区域由荒服边地、无序市井,向建州立县、拓展城邑、治理经济和定国安边的华丽转型。这是漳州建置前夕闽粤边邑自然状态下,商品交易呈现繁华气象的历史缩影。作者张循之生活于武则天统治时期,与陈元光相近。历宋元明初持续发展,漳江航运逐渐衰微,明中后期海澄月港后来居上。

无人直升机发动机再启动电源系统可在无人机发动机发生空中停车时提供再启动电源,是无人机安全、可靠运行的重要保障之一。针对镉镍蓄电池组存在的质量重、具有记忆性等缺陷,设计了一套无人直升机发动机再启动电源系统。该系统主要由锂电池组、BMS模块、充电模块三部分构成:其中锂电池组采用4串高倍率磷酸铁锂电池串联而成;BMS模块可准确测量电池单体电压、总电压、总电流及温度等信息,并采用EKF方法准确估算电池S OC,同时具有故障诊断功能;充电模块采用恒压恒流型BUCK电路,为电池组进行恒流串充。该系统在进行振动实验、冲击、加速度及温度冲击实验验证后仍可正常工作,且全温度范围SOC估计误差小于8%,体积小,质量轻,对于提高无人直升机的电性能和安全可靠运行具有重要意义。
