摘要

The remote supervisory control and data acquisition (SCADA) system is necessary for the wind turbine (WT) operation and the management of a wind farm. Technicians can resolve minor WT failures remotely and prepare equipment and spare parts for an on-site maintenance in advance with the aid of the SCADA system. This work is a case study, malfunction of the SCADA system for a wind farm in middle-Taiwan was encountered but the maintenance of WT manufacturer was no longer available due to the company bankruptcy. Since the emerged SCADA system failure is mainly caused by the storage and access of database, an auxiliary SCADA system based on the open platform communication (OPC) was designed to recover the SCADA system function. The OPC-based SCADA system is capable of retrieving data and reconstructing data structure from the WT controller directly. The rebuilt database has been employed in a front-tier web-based interface to regenerate the monitoring function for this wind farm.

此研究探討消失性商源對風場運作造成之影響，SCADA系統用於風機之遠距監控與數據收集，對於風場之運作調控與風機維護相當重要。本文研究對象為台灣中部之風場，由於風機母廠倒閉使得風場SCADA系統無法進行維護與升級，間接導致風機的可利用率大幅降低，有鑑於風機原廠軟體並非開源架構，本研究採用OPC開放平台架構進行輔助軟體開發，藉由直接與風機硬體通訊方式達成數據雙向傳輸之目的，除了重建監控與基本調控功能外，亦開發手機監控介面提高輔助SCADA對於風場監控的實用性與即時性。
