CONTROLLER OF FREQUENCY CONVERSION SYSTEM
Document Type and Number:
Japanese Patent JP2018121379
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a controller of a frequency conversion system, which can suppress voltage fluctuation that occurs in a load system and can speedily settle the voltage fluctuation.SOLUTION: A controller of a frequency conversion system for connecting a rotary frequency converter 13 and a static frequency converter 14 in parallel with one of power systems having different frequencies as a power supply system 11 and the other system as a load system 12 and cooperatively controlling the rotary frequency converter 13 and the static frequency converter 14, which interconnect each other comprises: a power supply control section 22 for controlling the static frequency converter 14 so that prescribed power is supplied from the power supply system 11 to the load system 12; and a reactive power fluctuation compensation section 23 for operating a reactive power adjustment command for adjusting reactive power fluctuation accompanying the voltage fluctuation of the load system 14 and outputting the command to the power supply control section 22.SELECTED DRAWING: Figure 1
