基于故障相相角的单相自适应重合闸

Single-phase adaptive reclosing based on phase angle of fault

为了避免重合闸重合于永久性故障,根据永久性故障过渡电阻较瞬时性故障过渡电阻小且衰减速度快的特点,提出了基于故障相相角的自适应重合闸判断方法。利用MATLAB中PSB模块进行仿真,对该方法进行验证并提出了最终的判据。

The method to judge adaptive reclosing based on phase angle of fault is put forward to avoid that adaptive reclosing coincides due to permanent failure,in accordance with the characteristic that transition resistance of permanent failure,compared with that of transient failure is much smaller and decays more rapidly.Through simulation PSB module in MATLAB,the method is tested and verified and the final evidence is proposed.
