  • 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.
