技術說明

本發明是有關於一種併網型太陽光電發電方法，其主要係令太陽能板以電壓控制方式調控其增載、減載程序，令其輸出電壓自動調到最大功率點下工作，輸出最大光電能，而於太陽能板所連接之變流器以電流控制方式，控制注入電網電流同步於電網電壓。太陽能板最大功率點之電壓決定是藉由感測電池開路電壓之量測來完成，使得其無中斷系統發電之虞，且無擾動量大小及等待系統穩定時間設定的問題，可促使太陽能板快速進入最大功率點下工作，保證發電系統的連續運轉，並於操作控制上極為簡單，而在其整體施行使用上更增實用功效特性者。 The invention relates to a grid-connected photovoltaic generation method. Primarily, a load increment procedure and a load reduction procedure of a solar panel are adjusted and controlled through a voltage control process. Thus the output voltage of the solar panel can be tuned automatically toward the maximum power point, and then the maximum power output will occur. An inverter connected to the solar panel can control the injected current to be synchronized to the ac source voltage through a current control process. The maximum power point voltage of a solar panel can be decided from sensing the open-circuit voltage of a sensing cell. Thus the solar panel can be operated under the condition that the operating voltage is tuned toward the maximum power point rapidly to ensure the continuous operation of the generation system. Moreover, the operation and control are very simple, so as to increase the practicability and efficiency for the whole implementation.
