Abstract: In small and medium-sized permanent magnet synchronous wind turbines, the bridge rectifier + DC / DC converter topology has the advantages of simple structure. The DC / DC circuit has Boost and Buck topologies. Exploring the difference between the maximum power point tracking ( MPPT ) control performance of the two is the key to its optimal design. The measurement and control system is an important means of performance analysis. Through the overall scheme design of the system, the system parameters and indexes are confirmed. The four-leg DC / DC topology is analyzed, and the acquisition of system voltage, current, power and frequency is realized based on high-end current sampling and isolated sampling technology. The power drive and single chip microcomputer control circuit are designed. The software of MPPT climbing search method suitable for single chip microcomputer is discussed. The software design and implementation of the upper computer control system based on LabVIEW is given. The measurement and control system is built, and the MPPT and two topology measurement and control results are compared. The experimental results show that the measurement and control system has achieved the design goal.
Key words : LabVIEW;wind power generation system;DC/DC converter;measurement and control system;data acquisition and processing

引言

時(shí)代背景下,國(guó)家正在推動(dòng)對(duì)可再生能源的研究[1]。風(fēng)能作為可再生能源,具有成本低、分布廣等特點(diǎn),已經(jīng)成為人類生活與發(fā)展離不開(kāi)的重要資源之一[2]。因?yàn)轱L(fēng)力發(fā)電可以有效地利用風(fēng)能產(chǎn)生電力,所以風(fēng)力發(fā)電的研究越來(lái)越受人們的關(guān)注[3]。在中小型永磁同步風(fēng)力發(fā)電機(jī)中常用的橋式整流+DC/DC電路結(jié)構(gòu)所組成的風(fēng)力發(fā)電機(jī)系統(tǒng)[4-5]中,利用Boost電路[6-9]和Buck電路[10-13]控制風(fēng)力發(fā)電機(jī)進(jìn)行最大功率點(diǎn)跟蹤(Maximum Power Point Tracking,MPPT)控制是常用的控制方法。

由文獻(xiàn)可知,Boost與Buck有不同的應(yīng)用場(chǎng)景,但目前對(duì)于兩種拓?fù)淇刂葡碌墓ぷ魈匦苑治龊蛯?duì)比較少。針對(duì)分別在兩種拓?fù)淇刂葡碌?a class="innerlink" href="http://www.theprogrammingfactory.com/tags/風(fēng)力發(fā)電系統(tǒng)" target="_blank">風(fēng)力發(fā)電系統(tǒng)MPPT特性分析與限制條件的研究,設(shè)計(jì)了一套風(fēng)力發(fā)電系統(tǒng)MPPT特性測(cè)控系統(tǒng),用于對(duì)特性進(jìn)行分析、對(duì)比與研究,并通過(guò)理論分析,確定了測(cè)控系統(tǒng)的測(cè)控參數(shù)與指標(biāo)。硬件部分,搭建橋式整流+ DC/DC電路、檢測(cè)電路和控制電路。軟件部分利用STC32G[14]單片機(jī)NI的LabVIEW開(kāi)發(fā)平臺(tái)[15-16]完成。整個(gè)測(cè)控系統(tǒng)可以完成對(duì)橋式整流+DC/DC電路拓?fù)渌M成的風(fēng)力發(fā)電系統(tǒng)進(jìn)行驅(qū)動(dòng)控制和數(shù)據(jù)采集與處理。
