Classification line selection method for single-phase earth fault of resonance earthing system
TL;DR: In this paper, a classification line selection method for the single-phase earth fault of a resonance earthing system was proposed, which comprises the steps of calculating the selected frequency band of the system according to the grid structure and the line parameters of a power distribution network.
Patent
Power distribution network fault arc extinction method by connecting neutral point to the ground through multi-level converter
TL;DR: In this paper, a cascade H-bridge multi-level converter is adopted and directly connected at the position of the neutral point of a power distribution network through a reactor, and the offset currents are quickly put into the multi-layer converter, the multilevel converter is controlled by aid of the current tracking control algorithm and the PWM (Pulse-width modulation) modulation strategy to generate offset currents.
Patent
Distribution network ground fault arc suppression method based on three-phase cascade H bridge converters
TL;DR: In this paper, a three-phase cascade H bridge converters are adopted to replace arc suppression coils and mounted between phase lines and the ground, and power is supplied to capacitors on the direct current side of the converters by using phase voltages, so that boosting transformers and grounding transformers are saved.
Patent
One-phase grounding clustering line selection method of resonant grounding system
TL;DR: In this article, a resonant grounding system fault line selection method with clustering achieved by means of time-frequency matrix singular values is proposed, where the singular values serve as the characteristic quantity of transient-state zero-sequence currents of each circuit and the bus.
Patent
