| 摘 要： | 传统的发电机内电势与功角通过实时测量发电机端电压电流以及发电机直轴电抗Xd和交轴电抗Xq计算得到.由于发电机在不同运行状态下Xd,Xq发生变化,产生计算误差.为此,提出一种转子位置测量法,利用发电机组的键相脉冲信号和机端电压来测量发电机内电势相角与功角.该方法不受发电机等效计算模型和同步电抗参数误差的影响,具有较高的精度,适用于电网扰动和暂态过程的实时功角测量.

| Abstract: | In traditional engineering applications,the internal voltage and power angle of generators are often measured by the electrical calculation method.In the method,the internal voltage and power angle of generators are calculated by direct-axis reactance Xd,quadrature-axis reactance Xq,terminal voltage and current which measured real-time.This calculation method may result in deviation because the value of Xd and Xq may be changed when the generator running in different status.This paper proposes a kind of rot... |
