數位化太陽光電發電系統市電併聯型變流器之研製

Development of a Digitized Grid-Connected Inverter for Photovoltaic System

指導教授 : 呂文隆

摘要


本文旨在研製一數位化太陽光電發電系統市電併聯型變流器,前級太陽能電池陣列分別利用擾動觀察法、斜率攀爬法及短路電流法控制直流升壓式截波器,以達到最大功率追蹤控制。後級利用電壓源電流控制法控制單相全橋式變流器,將直流電轉換成交流電並與市電併聯。在最大功率追蹤控制部份,所得的最大功率輸出分別以Matlab模擬與PVPM1000C實際量測的太陽電池特性曲線作比較,以驗證控制方法之正確性。在變流器部分,則利用Powersim模擬軟體模擬單相全橋式變流器的輸出特性,作為整體系統設計規劃之基礎,本文系統以數位信號處理器(DSP, TMS320LF2407A)作為控制核心,完成1.31kW數位化控制的市電併聯型太陽光電發電系統,於市電併聯時整體系統效率可達82.01%。

This thesis presents the development of a digitized grid-connected inverter for photovoltaic system. The of perturbation and observation method, hill-climb method, and short-circuit current method are applied separately to control DC/DC boost chopper to achieve maximum power point tracking control in the output of solar array. A voltage-Fed current-controlled method is used to the single-phase full-bridge inverter to convert direct current to alternating current and connect to the grid. The maximum power points from the characteristic curves based on the simulation of Matlab and the measurement of PVPM1000C are used to verify the performance of maximum power point tracking control. The output characteristics of the single-phase full-bridge inverter was simulated using the Powersim software for system design. A digital signal processor (DSP, TMS320LF2407A) is applied to the control system to accomplish a 1.31kW digitized control grid-connected photovoltaic generation system and the system efficiency is up to 82.01%.
