摘要
提出了高压电力计量系统网络故障模型。首先,通过对不同负荷下计量系统电路参数的分析,得出网络阻抗与电流互感器一次侧短路之间的密切关系。其次,设计辅助电路用于检测阻抗的变化,从而导出故障检测模型。最后进行了仿真研究,以证明模型对故障检测的有效性。
A network fault model for the high voltage electric power metering system is proposed in this paper. Firstly, the closed relations between short circuit of the primary side of impedance changes from which the fault model is derived. Finally, simulations are performed on the model to demonstrate the efficiency of the fault detection model.
