| description | Purposes With the continuous access of distributed generator (DG) in the traditional distribution network, it has brought serious challenges to the distribution network protection configuration. Based on the analysis of the amplitude and phase characteristics of different types of DG fault current in distribution network line fault, this paper proposes a distribution network pilot protection scheme based on the amplitude and phase characteristics of fault sequence current. Methods The scheme uses the amplitude and phase difference characteristics of each sequence fault current at both ends of the line to construct the protection action amount and braking amount respectively. By setting the protection parameters reasonably, the selectivity and sensitivity of complex distribution network protection with different types of DG can be taken into account. Findings The protection scheme setting is simple, real-time adjustment is not required at the operation stage, and the computational power of the protection equipment is low. Finally, the effectiveness of the protection scheme is verified by a simulation example built by RTDS. |
