Title:
分散型電源の系統連系装置
Document Type and Number:
Japanese Patent JP7028034
Kind Code:
B2
Abstract:
To determine a deposition of a relay for system interconnection at relatively low cost in the case of power failure in a system interconnection device for distributed power sources.SOLUTION: In a system interconnection device 10, a first parallel-off relay 15a provided in a first electric wire L1 is connected to a second electric wire L2 via a second connection electric wire 24 in which a first energy consumption component 24a consuming electric energy charging a capacitor 14c is provided, when switched to a second connection state. A second parallel-off relay 15b provided in the second electric wire L2 is connected to the first electric wire L1 via a third connection electric wire 25 in which a second energy consumption component 25a consuming electric energy charging the capacitor 14c is provided, when switched to the second connection state. On the basis of a detected current state or a detected voltage state during discharge of the capacitor 14c, a determination section 16b determines a deposition state of the first and second parallel-off relays 15a and 15b.SELECTED DRAWING: Figure 1
