Title: Phase rotation direction determining method for wind power generator
Inventor: FUKUDA MITSUYOSHI
IPC: F03D7/04
Filed: 2001-05-25
Abstract: PROBLEM TO BE SOLVED: To determine a phase rotation direction of a wind power generator without rotating the wind power generator as an electric motor by an external power source. SOLUTION: This is the phase rotation determining method when connecting an induction generator output terminal of a wind power generation device which carries out linking operation with the power source system. This phase rotation determining method comprises the steps of: measuring the phase rotation direction of the power source system by a phase rotation speed indicator; idling the induction generator connected to a windmill to generate as minute voltage due to remnant magnetism; measuring the phase rotation direction of the minute voltage due to the remnant magnetism by a sensitive phase rotation meter; and comparing the measured phase rotation direction of the power source system with the phase rotation direction of the induction generator in which the minute voltage due to the remnant magnetism is generated, to confirm that the phase rotation directions are the same.  The sensitive phase rotation meter can measure a region between a minute voltage of several ten m V and a voltage of several hundred V.
