摘　　要：随着电网不断升级改造,主干电网随着分布式电站的并入导致电压提高,从而系统短路阻抗降低,短路电流增加。在主变低压侧短路电流增大,使得母线抗短路能力变得尤为重要,通过利用零损耗深度限流装置,在保证低损耗、节能的情况下,还能最大限度的提高母线抗短路能力。With the continuous upgrading and transformation of the power grid,the voltage of the main power grid increases,the distributed power plants connected to the grid increase,the short-circuit impedance of the system decreases,and the short-circuit current increases.with the increase of short-circuit current in the low-voltage side of transformer,the anti-short-circuit ability of bus becomes particularly important.By using zero-loss depth current limiter,the anti-short-circuit ability of bus can be maximized under the condition of low-loss and energy-saving.
