摘要： A system Includes a first DC rail and a second DC rail, and a rectifier coupled with the first and second DC rails. A multilevel converter is also coupled with the DC rails and operable to limit input current harmonics to the rectifier. Differences between voltage phase and current phase in AC electrical power supplied to the system are compensated via closed loop control of a voltage output of the multilevel converter.

摘要： 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.

摘要： 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.

摘要： Technologies for detecting a fault location in a DC electrical distribution system include a bus protection unit that monitors a DC electrical bus. The bus protection unit includes at least one sensor to produce sensor data indicative of one or more characteristics of the DC electrical bus monitored by the bus protection unit. The bus protection unit monitors the sensor data, determines whether a fault has occurred based on the sensor data, and determines whether the fault occurred within a bus zone defined by the DC electrical bus in response to determining that the fault has occurred. Further, the bus detection unit trips isolation devices within the bus zone in response to a determination that the fault occurred within the bus zone or a communication from another bus protection unit indicating the fault has occurred within the bus zone. The bus protection unit transmits a bus fault indication signal to another bus protection unit in response to a determination that the fault has occurred.
