High Voltage Soft Grid-connected Device

CGC series high-voltage soft grid-connected device is soft grid-connected device designed for a high-voltage motor with a relatively new concept, which is mainly suitable for the control and protection of the start and stop of the motor. This device adopts optical fiber isolation, dynamic and static voltage equalization protection measures, and realizes the high-performance operation of the equipment. The device performs closed-loop control of the SCR through the grid connection momentarily, and uses the grid reactive power to excite the motor. At the same time, a special algorithm for soft grid connection is adopted, which reduces the power oscillation problem in the grid connection link.

The use of a soft grid-connected device can reduce the grid-connected impulse current of the motor and reduce the impact on the grid and the motor itself. At the same time, it also reduces the impact on the mechanical equipment, so as to prolong the service life of the equipment and reduce the failure and downtime.
