Title:
PWM電力変換器の並列運転装置
Document Type and Number:
Japanese Patent JP5803681
Kind Code:
B2
Abstract:
To perform an anti-windup control without interference with a cross current compensating function even in case of voltage saturation. There is provided a feedback value calculating section to calculate an average of voltage commands V1_cmd, V2_cmd after output limitation, as a feedback value. As a deviation used for an integral calculation of a current control section 6a, 6b, a sum obtained by adding a product to a deviation between a current command value Id_cmd, Iq_cmd and a current detection value Id_det, Iq_det is used. The product is a quantity obtained by multiplying a saturation quantity by a feedback gain Kfb. The saturation quantity is a saturation quantity of an operation quantity limited by a voltage command limiting section 3a, 3b, and the saturation quantity is a deviation or difference between a feedback value V_fb (Vd_fb, Vq_fb) and the voltage command Vd_cmd.
