【摘要】 本文分析了补偿电网的基本原理,研究了基于工控机的调容式消弧线圈自动跟踪补偿装置。通过分析自动补偿电网单相故障选线方法:零序电流变量法、有功法、零序导纳法,研究了接地选线装置,并在此基础上给出了补偿电网自动调谐和选线一体机的综合控制思路。

【Abstract】 The paper analyses the principle of the compensating network, and studies tracking compensation director of the Peterson coil with the thyristor series capacitors based on industrial personal computer. By analyzing the method of single-phase earth fault line selection, based on active power, variety of residual current, phase-to-ground Admittance, the paper studies the device of single-phase earth fault line selection. The paper puts forward the integral control of automatic resonance and faulted line selection.
