Abstract

In response to the National Grid's initiative for rapid isolation of permanent faults, this paper proposes a rapid and safe disposal technique for grounding faults by regulating the neutral point voltage. Targeting permanent grounding faults, the technique regulates the neutral point voltage to elevate the fault phase voltage, thereby increasing the characteristics of high-resistance grounding and achieving high sensitivity grounding protection. Additionally, a control strategy of "ground fault suppression - load transfer - fault line segment isolation" is proposed. Taking the example of on-site distributed feeder-level rapid intelligent FA, this paper designs an active voltage boosting protection scheme for distribution grid systems to achieve rapid isolation of permanent faults and uninterrupted load transfer in non-fault segments.
