摘要： Provided are a DC power transmission system, a method, and a central server for the system capable of promptly, safely, and surely recovering a section where a fault is removed to a system when the fault occurs in a DC power transmission path. When an occurrence of a fault in a DC power transmission path formed by diverging into a multiple paths or converging a multiple paths is detected, first, a switch 6 is opened to disconnect a fault section 23 from the DC power transmission path, second, after the opening, one of the opened switches 6 is closed, third, after the one switch is closed, when the continuation of a fault is detected, the one closed switch 6 is opened again, and fourth, after the closing of the one switch 6, when no continuation of the fault is detected, all switches 6 opened to disconnect the fault section 23 from the DC power transmission path are returned to the ON status, thereby recovering the fault section.

摘要： According to one embodiment, there is provided a control apparatus including a first control calculation device (1) that calculates an output command value of one or more main circuits (5) including a semiconductor switching element; and one or more second control calculation devices (8) that convert the output command value to a gate signal of the semiconductor switching element. The output command value is transmitted from the first control calculation device (1) to the second control calculation devices (8) by wireless communication. The second control calculation devices (8) transmit the gate signal converted from the transmitted output command value to a gate substrate (4) that drives the semiconductor switching element based on the gate signal.

摘要： A power conversion device capable of controlling a capacitor voltage balance among chopper cells. Each phase arm 2 including chopper cells 3 connected in series and divided into upper and lower arms 21, 22 is connected to a DC power supply via first and fourth switches 41, 44 at both ends. Second and third switches 42, 43 in parallel with the phase arm 2 are connected in series between the first and fourth switches 41, 44. An output terminal 23 is provided between the upper and lower arms 21, 22, a neutral-point 5 is provided between the second and third switches 42, 43, and the neutral-points 5 in respective phases are connected with each other. A controller 6 forms, for each voltage phase, a circuit in which the two phases are connected in parallel, and the phase arm 2 in the other phase is connected in series to the phase arms 2 connected in parallel. The controller 6 superimposes an AC current on a P-N circulating current flowing through such a circuit, and controls the AC current to suppress an imbalance between the upper and lower arms 21, 22.
