摘要
长葛市佛耳岗水库水电站电抗分流式发电机并列运行时，出现剧烈无功振荡。采用副绕组顺转120°接电抗器，改变抽头位置，增设双投开关，解决了振荡问题，给电站提供了多种运行方式。
In the Fuergang hydropower station, there happened a violent reactive power oscillation when the small reactor-starting generator was put into operating with the large generator. For overcoming this trouble, the reactor's windings were reconnected after the subwinding phase shifted 120°clockwise and the tap of mainwinding shifted near the neutral point.In addition,a two-way switch was installed in the excitation circuit. Thence, the oscillation disappeared, and the generators can be operated on various mode.
