可控消弧线圈增容改造在攀钢电网中的应用

Application of Transformation of Controllable Arc Suppression Coil Capacity Increase in the Power Grid of Pan Steel

随着配电网发展,攀钢新冶炼变电站10 k V可控消弧线圈出现容量不足的问题,影响系统设备运行安全。通过对现状深入分析,提出了以可控消弧线圈装置自动跟踪计算的电容电流为数据依据,并通过调整配电网运行方式找到最大电容电流值和工程计算共同核算消弧线圈增加容量的方法。实际应用结果表明,该方法简单、实用、有效。

With the development of the power distribution network, the Xinyelian sub-station 10 kV controllable arc suppression coil of Pangang had the problem of insufficient ca-pacity, which influenced the operation safety of system equipment. Through in-depth analysis of the present situation, it was put forward that taking the capacitance current automatically tracked and calculated by the controllable arc suppression coil device as the data basis and by adjusting the power grid operation mode to find the maximum capacitor current and the method for engineering calculation of common accounting arc suppression coil capacity in-crease. Practical application results have shown that the method is simple, practical and effec-tive.
