Title:
DC POWER NETWORK AND CONTROL METHOD OF DC POWER NETWORK
Document Type and Number:
Japanese Patent JP2021010201
Kind Code:
A
Abstract:
To provide a DC power network which shortens power failure time as much as possible while overcurrent to a DC electric circuit is prevented when a part of the DC electric circuit is separated in the case of fault occurrence and power supply is continued via a bypass in the DC power network having a plurality of power networks which can mutually supply power, and to provide a control method of the DC power network.SOLUTION: A DC power network comprises a first power network and at least one second power network, which can mutually supply power. If a fault occurs in a DC electric circuit between the first power network and at least one second power network when power is supplied from the first power network to at least one second power network, supply power to at least one second power network is reduced or at least one second power network is set to an off-grid state.SELECTED DRAWING: Figure 1
