Title:
A method and a device for tracing the place of an arc and extinguishing it
Document Type and Number:
Japanese Patent JP6196293
Kind Code:
B2
Abstract:
The disclosure relates to a method for localizing and quenching an arc in a PV generator of a PV system, wherein the PV generator includes at least two PV subgenerators. An arc quenching circuit is associated with each PV subgenerator. The method includes detecting an arc in the PV generator. Then, a probability value is determined for each of the PV subgenerators, wherein the probability value is correlated with a probability that the arc is located in the corresponding PV subgenerator. A sequence for activating the arc quenching circuits is then determined that is dependent on the determined probability values. Then, the arc quenching circuits are activated successively in the order of the determined sequence.
