摘要
双绕组电抗器分流励磁发电机并列运行时会出现严重的振荡问题。作者结合实践提出了解决方法:减小电流源的励磁分量,降低励磁正反馈强度;电流源减小的励磁分量用增大电压源的励磁分量来弥补;使电压源的励磁分量可调。
As parallel running of shunt-excited generators with double-wound reactor,a serious oscillation problem is faced. Based on practice the author suggests the following technical measures: decreasing the exciting component due to current source, and reducing the positive feedback intensity of excitation; increasing the exciting component due to voltage source to make up for the deercase of exciting component due to current source; making the exciting component due to voltage source to be adjustable.
