本文旨在研製數位鎖相迴路用於市電電壓相位偵測之三相市電併網系統。採用同步旋轉座標轉換系統下,對市電側之電壓相位角作鎖相控制,並以數位程式完成之。三相永磁式同步發電機之功率控制方面,採用三相全橋二極體整流器及昇壓型直流-直流功率轉換器,建立穩定的直流鏈電壓以供三相直流-交流功率轉換器與市電併網。另於三相直流-交流功率轉換器控制,採用電壓空間向量脈波寬度調變控制策略,以降低直流鏈電壓的工作範圍及減少電流的總諧波失真率。在三相市電側併網之功率控制採用同步旋轉座標之交-直軸電流及直流鏈電壓閉迴路控制二個方法。其中直流鏈電壓控制法具有功率補償及提高直流鏈電壓響應速率之優點。
本文建立三相直流-交流功率轉換器之數學模式,並以套裝軟體Matlab/Simpower進行系統模擬,作為系統控制器設計之依據。文中採用數位信號處理器TMS320F2812作為整體系統之控制核心,由軟體程式實現控制。本系統已完成378W市電併網供電系統,線電壓為220V,頻率為60Hz,可提供實功率至市電側,藉由實驗結果驗證理論分析之正確性,且整體系統運轉之效率為85%。
The thesis presents the phase-angle detection of utility voltage using phased-locked-loop (PLL) technique for three-phase grid-connected power converter. A three-phase permanent–magnet synchronous generator is used to generate power for three-phase diode rectifier and boost-type dc-dc converter to maintain stable dc-link voltage for grid-connected three-phase power inverter. The proposed three-phase inverter uses voltage space vector pulse-width modulation technique to reduce the dc-link operating voltage range and the output current harmonics. Three-phase grid connection is conducted with two separate approaches:the control of q- and d-axis current under synchronous frame as well as the control of dc-link voltage. The latter method, namely, the closed-loop control of dc-link voltage provides the advantage of better input-output power balance and faster dc-link voltage response.
In this thesis, the digitized mathematical model and controller design are built and simulated by MATLAB/Simpower. Then, the high-performance and low-cost digital signal processor TMS320F2812 is used to control the power converter. The rated line-voltage is 220V and the frequency is 60Hz. Experimental results show that the power converter supplies 378W with the corresponding efficiency of 85% using ac-dc-ac power converter.
