| 摘 要： | 本文采用实时监测系统中性点电压,电流量的方法,求出系统的电容电流及脱谐度,利用微机控制自动调谐装置实施消弧线圈的有载调节。并且通过串联阻尼电阻以限制调节过程中谐振引起的电压升高。该装置对于小电流接地系统及实现变电站无人值班具有广泛的应用价值。

| Abstract: | A real - time method monitoring voltage and current at a system's neutral point is adopted to obtain the capacitive current and tuning degree of the system. Micro - computer is employed to control autotuning device and carry out load adjustment of Petersen coil. Meanwhile, the voltage rise caused by resonance in course of adjusting is controlled by series damping resistance. This device is practical in the realisation of unattended power substation and earthing system with little current. |
