摘要
阻抗是电路研究的重点参数之一,通过对阻抗的详细测量计算可以掌握电路的实际运行状态,有助于分析电路里电流信号传输的稳定性。近年来,在线测量技术成为电力行业研究的新方法,在不切断电路运行的情况下测量阻抗值大小,可以维持电路状态的持续性。笔者研究了在端口信号能量测量基础上完成的阻抗测量,体现出电力设备运用条件下阻抗的变化影响,为电力系统运行监测提供了可靠的数据参考。
Impedance is one of important parameters in circuit research,and it helps to analyze the stability of the signal transmission circuit current through the impedance measurement and calculation can grasp the actual operation of the circuit state.In recent years,online measurement techniques become new method of electric power industry,impedance value measured in the case of do not cut off the circuit to run size,easy to maintain the continuity of the circuit state.I studied the port signal energy measurement on the basis of impedance measurements and it reflected the impact of changes in impedance in the power equipment use conditions provides a reliable reference data for power system operation and monitoring.
