Title:
バッテリー用コンバータ及び三相蓄電システム
Document Type and Number:
Japanese Patent JP7020824
Kind Code:
B2
Abstract:
To provide a three-phase power storage system capable of effectively utilizing an electric power by charging of a battery by using the electric power of a solar cell panel during an autonomous operation.SOLUTION: A BM/DC converter 3 switches a current control on a battery 102 side that matches a BAT current FB to a current command to a voltage control on a link side that matches a link voltage FB to a voltage control, when an operation mode is switched from a normal operation to an autonomous operation. A selector 10 selects a current command generated so that a link voltage deviation becomes 0 by a controller 14 in stead of a BAT current command input from a trunk control device 1, when the operation mode input from the trunk control device 1 is switched from the normal operation to the autonomous operation. A controller 17 generate a command so that the deviation between the current command and the BAT current FB becomes 0, and a power unit 21 performs an electric power conversion of a DC/DC between the link side and the battery 102 on the basis of the command.SELECTED DRAWING: Figure 3
