  • Patent number: 9882370
    Abstract: A multi-faults service restoration method for a power distribution network overcomes the defect that a traditional service restoration method for the power distribution network cannot solve multi-faults. The method includes the steps of performing multi-faults judgment on multi-faults with processing unfinished, to form many multi-faults and many single-faults; then performing unaided fault recovery area division on the multi-faults, and performing power restoration on unaided fault recovery areas one by one; and after the multi-faults are processed, performing power restoration on each single-fault.

  • Patent number: 9575102
    Abstract: A dispersed state monitoring device for distributed generation includes a power module, an input conditioning module, a data processing module and a network communication module which are connected one after another in this order. The power is input, via a civil plug and a 220V power socket, to the power module and the input conditioning module in the device at the same time. The power module ensures normal operation of the device through conditioning of a voltage. The input conditioning module is configured to condition input voltage signals, extract voltage transient-state and steady-state signals to be analyzed, and inputting the signals to the data processing module. The data processing module is configured to analyze the voltage transient-state and steady-state signals, judge the operating state of the distributed power source, and output a judging result to the network communication module. The result is output from the network communication module via a standard RJ45 Ethernet interface.
