Document Type and Number:
WIPO Patent Application WO/2020/178914
Kind Code:
A1
Abstract:
An electric operation device for a tap changer according to an embodiment of the present invention has a reception unit, a driving unit, a detection unit, and a derivation unit. The reception unit receives a control command. When the control command is received by the reception unit, the driving unit drives a main drive shaft using a motor, thereby changing the tap of the tap changer. The detection unit detects the rotation position of the main drive shaft during changing of the tap. The derivation unit derives the displacement amount of the stop position of the tap on the basis of the stop position of the tap associated with the rotation position detected by the detection unit, and of a target stop position of the tap.
