Title:
CONTROL DEVICE OF POWER CONVERTER DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/074715
Kind Code:
A1
Abstract:
Provided is an elevator monitoring device that can appropriately compensate for system voltage when an unbalanced short circuit occurs. This control device of a power converter device comprises: a current command value generating unit that generates a provisional normal phase d-axis current command value, a provisional normal phase q-axis current command value, a provisional reverse phase d-axis current command value, and a provisional reverse phase q-axis current command value to compensate for the voltage on the AC side of a power converter; a limiting unit that sets each limit value of the provisional normal phase d-axis current command value, the provisional normal phase q-axis current command value, the provisional reverse phase d-axis current command value, and the provisional reverse phase q-axis current command value so that the current value on the AC side of the power converter does not exceed a preset value; and a control unit that controls the power converter based on a determined normal phase d-axis current command value, a determined normal phase q-axis current command value, a determined reverse phase d-axis current command value, and a determined reverse phase q-axis current command value obtained respectively from the provisional normal phase d-axis current command value, the provisional normal phase q-axis current command value, the provisional reverse phase d-axis current command value, and the provisional reverse phase q-axis current command value within the limit value.
