Aiming at the single-phase grounding short-circuit fault of photovoltaic grid-connected station based on positive-sequence control, this paper studies internal faults and external faults of photovoltaic plant respectively and proposes their adaptive fault location algorithms. For the external fault of the photovoltaic plant, this method only uses the electrical information of the opposite end system of the photovoltaic plant to get the analytical expression of the fault distance, which is not affected by th...
