中文摘要 | 同步發電機磁場失磁將會造成發電機故障以及對電力系統產生穩定度影響的事故。本文係針對大型發電機組在不同輕重負載特性下失去磁場,探討其阻抗變化特性,並藉大型發電機組之失磁保護架構,說明同步發電機失磁保護設計規劃之原理。 |
英文摘要 | The event of loss of field for large turbine generator will cause some severe results which will damage the generator itself including rotor and stator and affect grid stability. This study is to focus on loss of field with different power generation conditions, which will accompany corresponding impedance trajectories. Accordingly, the scheme of loss of field protection will be applied to those different situations and get an optimal solution. |
