摘要
本文用有限元法计算了170MW凸级同步发电机在额定励磁、额定电压条件下,各工况的磁场,由此得到发电机的饱和功角特性和不同功角下的场图和气隙磁场变化,从而定性地阐明了同步电机发生“不稳定”的原因。
Using the FE method,the field distribution of a large synchronous generator for various load is calculated under rated excitation and terminal voltage. The saturated power-angle characteristic, the air gap field with different power -angle are obtained.The causes for unstability occurred in synchronous machine are qualitatively analyzed.
