The Relationship

The application of traditional distance relay for four-parallel transmission lines is adversely affected by the mutual coupling between the lines. The result will lead to not achieved measured impedance calculation. And it has an effect on the operation of ground protection. In this paper, A new ground distance algorithm is proposed for single-phase grounding fault of four-parallel transmission lines. Based on the case of single-phase grounding fault, The first the relationship between fault point voltage and the voltage at protection installed location is presented by twelve-sequence component method. In the basis, According to the relationship of phase corner between the fault voltage and the fault current to eliminate the effect of fault voltage. The simulation results show that the new scheme has high sensitivity and reliability under different single-phase grounding fault of four-parallel transmission lines.
