Title:
FAULT DETECTION METHOD AND DEVICE FOR HIGHLY-TRUSTED POWER DISTRIBUTION NETWORK, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/075671
Kind Code:
A1
Abstract:
Disclosed in the present invention is a fault detection method for a highly-trusted power distribution network. The method comprises: monitoring changes of electrical parameters in a power distribution network, the electrical parameters comprising at least two of a zero sequence voltage, a zero sequence current, a phase current, a phase voltage and a line voltage; and when the changes of the electrical parameters conform to preset fault determining conditions, determining that a specific type of fault occurs in the power distribution network. Also disclosed in the present invention are a fault detection device for a highly-trusted power distribution network, and a storage medium.
