  • DC power generation system and protection method for DC power generation system
    Patent number: 9866017
    Abstract: A DC power generation system in which an arc detector, comprising an arc noise analysis unit which detects an arc which occurs in a DC power generation system based on noise of signal of a voltage-current sensor, a voltage-current variation analysis unit for specifying an arc occurrence point in a case where an arc is detected in the arc noise analysis unit, a voltage-current operation point of output of each string is analyzed based on a signal from a voltage-current sensor and based on variation of voltage-current operation point before and after when an arc is detected and a switch control unit for controlling of opening or closing of a switch based on an arc specified result in a voltage-current variation analysis unit, is provided.
