由於風力發電機運轉時,將因負載增加而降低功率係數,導致系統不穩定造成電力損耗,同時使風力發電機轉速降低,進而影響風力發電機發電量。為了獲取最大功率係數,必須使風力發電機維持在最佳功率點附近運轉,並進行功率補償達到最佳功率點,以提升發電效率,減少不必要的電力損耗。
本文提出以LabVIEW環境下,設計即時風力發電機功率監控系統,使用兩個電池儲存風力發電機所產生的電力。利用LabVIEW程式結合USB-4711資料擷取卡,擷取電池電量,經由設計的LabVIEW程式判讀電池電量與瞬時充電電量。風力發電機在平時一般狀態下,額定充電電壓為12~15V,若電池充電效率降低,表示風力發電機槳片轉速降低,則運用電池剩餘電力進行功率補償,使槳片產生的機械功率及其激磁所產生的電功率達到最佳化,以提升整體風力儲能效率,並使槳片轉速達到最大功率點追蹤的要求。最後,對進行功率補償與未進行功率補償的情況下進行分析,並比較其轉子轉速回升時間之差異。
本論文另外使用LabVIEW中的DataSocket,發展出遠端監控功能,經由USB-4711資料擷取卡傳送命令,對風力發電機進行監控,並顯示出電池電位量及風力發電機的運轉狀態,達成遠端監控之目的。

In the operation system of the wind turbine, the power factor will be reduced by the increased load, it leads to power loss caused by the system instability, and makes the wind turbine speed is decreased, thereby the wind turbine generating capacity is affected. In order to obtain the maximum power coefficient, the wind turbine should be operated on the optimum power point. If not, the power will be compensated to achieve the maximum power point. It will enhance the power generation efficiency, and reduce unnecessary power loss.
In this paper, we present the real-time wind turbine monitoring program that designed in LabVIEW environment. The two batteries are used to store the electricity by the wind turbines. The battery power is retrieved by using LabVIEW program and the USB-4711 data acquisition card. When the battery power lower to 70% of the storage, the program will detect and charged instantaneously. If the battery charging efficiency reduced, it means that the wind turbine speed also reduced, and then carried out power compensation by battery. It makes mechanical power and electrical power achieve optimization. The system not only upgrade overall efficiency of the wind energy storage, but also achieve the maximum power tracking point.
DataSocket in LabVIEW is developed to a remote monitoring system, it can monitoring the wind turbine operation and shows the cell potential volume.
