FAULT POINT LOCATING APPARATUS, FAULT POINT LOCATING SYSTEM, FAULT POINT LOCATING METHOD, AND NON-TRANSITORY COMPUTER-READABLE MEDIUM
Abstract:
A fault point locating apparatus according to the present disclosure includes: a frequency characteristic calculation unit configured to calculate frequency characteristics after occurrence of a fault; and a post-fault-occurrence model analysis unit configured to add a model of a fault point to a pre-fault-occurrence model of a power transmission-and-distribution network so as to match the frequency characteristics after the occurrence of the fault and create a post-fault-occurrence model, thereby locating a fault point.
