220kV变电站主变低压35kV侧加装限流电抗器的可行性研究

由于电力系统容量的扩大,系统的短路电流随之增大,主变低压侧抗短路能力嗜待增强。通过在主变低压侧加装限流电抗器来限制短路电流是可行的方法之一。如何消除由于增加限流电抗器给系统产生的负面影响无疑成为我们面临的非常重要的问题。本文就能否采用限流电抗器来解决系统容量增大导致河北南部电网220kV变电站主变低压侧短路电流过大这一问题进行了一些有益的探讨。

Feasibility Study of Lateral Installation of Current Limiting Reactors of 220kV Main Transformer Low Voltage 35kV Substation

Short-circuit current of electric system is becoming larger owning to the enlargement of its capacity,so the ability of anti-short circuit on the low-voltage side of main transformer is necessary to be strengthened.One feasible way to limit short-circuit current is to add limiting reactors on the low-voltage side of main transformer.How to remove the bad effect to the system generated by adding limiting reactors has become a very important problem in front of us without any doubt.The paper carries out some ...
