| 中文摘要 | 本文主要目的在探討鑄造廠之保溫爐諧波異常問題。單相保溫爐為維持三相電流 平衡供電,於爐體內部三相電流平衡供電,於爐體內部三相電路裝置不等電容器與電感器, 因而與系統發生串聯共振,造成大量諧波電流注入保溫爐,影響爐體正常運轉,本文實際量 與模擬分析一實例諧波事故原因,並提出可能之改善對策。 |
| 英文摘要 | This paper investigates the harmonic amplification Problems in the holding furnace of a metallurgy plant, and presents the appropriate mitigation methods. There were some failures in the holding furnace caused by unidentified large harmonic currents. The holding furnace is a single phase inductive load. Capacitors and reactors being installed in holding Power system to make three phase balance a series resonance is opt to occur between the capacitors and pwere system. Field measurements and computer simulation are used to verify the disturbance Problems. Finally, inserting a suitable reactor in capacitors or installing an isolated transformer between MOF and holding furnace transformer is suggested. |
