    摘 要:分析了并網逆變器的三種拓撲結構的優(yōu)缺點,并根據實驗需要選擇了非隔離型拓撲結構作為實驗平臺主電路拓撲。采用IPM模塊為核心的逆變電路,控制部分采用通用逆變器控制器作為系統(tǒng)的控制核心,運用LabVIEW軟件實現了實驗平臺的控制系統(tǒng)和上位機監(jiān)控顯示系統(tǒng)的有機集成,對系統(tǒng)中的各個參量進行實時監(jiān)測,并完成了三相PWM逆變器的離網、并網實驗。實驗結果表明:控制系統(tǒng)給出的相位成功跟蹤電網的同步相位,始終與電網電壓的相位保持一致,并網成功。

    Abstract: Analysis was made to the relative merits of three kinds of topological structures in grid-connected inverter. According to the requirement of experiment, this paper chose the non-seclusion type topology as the main circuit topology of the experimental platform. The IPM module was the core of the inverter circuit. The control section adopted the common inverter controller as the control core of the system. The software LabVIEW was used to realize the control system of the experimental platform and the organic integration of the upper computer monitoring the display system, which monitored each parameter of the system in real time. The off-network and grid-connection experiments of three-phase PWM inverter were finished. The experimental results show that the phase given by the control system successfully tails after the synchronized phase of the grid, and brings into correspondence with the phase of network voltage from beginning to end, the grid successfully connected.
    Key words: IPM module; LabVIEW; inverter platform; grid-connection experiment; off-network experiment
