Title:
CONTROL SYSTEM AND CONTROL METHOD FOR POWER CONVERSION EQUIPMENT
Document Type and Number:
Japanese Patent JP2017143618
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a control system and control method for self-excited power conversion equipment, capable of accommodating changes in frequent flow directions.SOLUTION: A control system 1 for power converter includes: a control end switcher 8 for changing a limiter value on the basis of a DC current command value Idp; controllers 9-1, 9-2 for switching between voltage control and current control on the basis of the limiter value. The control end switcher 8 controls timing of changing the limiter value when switching between the voltage control and the current control.SELECTED DRAWING: Figure 1
