POWER-DISTRIBUTION-PATH PHASE-MANAGEMENT-ASSISTANCE METHOD AND POWER-DISTRIBUTION-PATH PHASE-MANAGEMENT-ASSISTANCE SYSTEM

摘要

Provided are a power-distribution-path phase-management-assistance method and power-distribution-path phase-management-assistance system that are capable of simplifying the phase management of a high-voltage power distribution path. At a phase management point on a three-phase AC power distribution path, the voltage values of each line distributing three-phase AC and the noise components superposed on each line are detected, and the phases of each line at the phase management point are estimated from the mutual complementation of the voltage value detection results and the noise component detection results.
