Abstract: A protection device (100/300) includes a diode (102) having its forward direction in a normal power flow of a region of a DC collection system, a first switch (104) in parallel with the diode (102), a second switch (106) in series with the diode (102) and a control unit (108) for controlling the switches (104, 106). The first switch (104) can be opened so that current can flow through the diode (102) in the forward direction without the first switch (104) bypassing the diode (102), and closed if no current is flowing through the diode (102) in the forward direction and power is needed upstream of the diode (102). The second switch (106) can be closed so that current can flow through the diode (102) in the forward direction to an AC grid interface of the DC collection system, and opened if no current is flowing through the diode (102) in the forward direction due to a fault in a DC feeder ('Feeder 1', 'Feeder 2') to which the protection device (100/300) is coupled.

Abstract: Methods and apparatus for protecting a direct-current (DC) electric power distribution system that includes one or more AC/DC converters and/or one more DC/DC converters, and one or more loads, connected by DC buses. An example method, which is carried out in response to the detection of a fault somewhere in the system, begins with limiting an output current of each of one or more of the converters so that each of the limited converters outputs a limited DC current at or about a corresponding predetermined current level. After the current limiting of the one or more converters has taken place, one or more protection devices in the system are activated, where the activating at least partly depends on the limited DC currents being at or about the predetermined fault current levels.

Abstract: While transient current magnitudes at different locations within a DC distribution system themselves are not a reliable indicator of fault location, it is recognized herein that accumulating energy or pseudo energy values provides a reliable basis for tripping the protection element at a fault location. Thus, in one aspect of the teachings herein, pseudo energy values are accumulated independently during a fault condition, for each of one or more protected branch circuits and the protection element for each such branch circuit is tripped responsive to the accumulated pseudo energy values reaching a defined pseudo energy threshold. The pseudo energy thresholds are defined so that the protection element in the branch circuit where the fault is located will trip first.

Abstract: An improved method of fault detection in a high-voltage direct current (HVDC) power transmission line (101 ) is provided. The fault detection is based on fault-induced travelling waves. The method comprises estimating an amplitude of fault-induced travelling waves at the fault location (1 07), and calculating a fault resistance (Rf) based on the estimated amplitude, an estimated pre-fault voltage at the fault location, and a surge impedance of the transmission line. The estimated fault amplitude and the estimated pre-fault voltage are calculated from voltage measurements performed at both ends (102, 1 03) of the transmission line. Further, a fault detection device (1 06) is provided.
