- main converter 500 according to Embodiment 3 of the present invention is similar to main converter 100 according to Embodiment 1, and includes first power converter 111 and second power converter. 112, an auxiliary power supply device 113, a voltage detection unit 114, and a filter capacitor 115.
- Main conversion device 500 further includes a current detector 551 and an operation control unit 520 instead of operation control unit 120 of main conversion device 100 according to the first embodiment.
- the current detector 551 is a device that detects a current input to the first power converter 111 and outputs an input current signal including an input current IS that is a value of the detected current.
- the current detector 551 according to the present embodiment represents a current flowing in the direction from the current collector 101 toward the first power converter 111 as a positive value, and represents a current flowing in the opposite direction as a negative value. To detect the magnitude and direction of the current.
- the direction and magnitude of the current input to the first power conversion unit 111 may be detected, and the method is not limited to this.
- positive / negative may be defined in reverse.
- the operation control unit 520 controls the operation and stop of the first power conversion unit 111 based on the regenerative opening command COR output from the cab 552, the intermediate link voltage EFC, and the input current IS.
- the regenerative release command COR is a command that indicates whether power regeneration to the overhead line 105 is permitted or restricted.
- the regeneration opening command COR may include a restriction value Ps1.
- the operation control unit 520 when the operation control unit 520 obtains the regenerative release command COR indicating that the regeneration of power to the overhead line 105 is restricted, the operation control unit 520 outputs the off operation control signal GC. Thereby, the 1st power converter 111 stops.
- the operation control unit 520 determines that the regenerative power PB generated by the induction motor 103 is equal to or lower than the auxiliary power supply power PA. Output GC. Thereby, the first power conversion unit 111 operates.
- the set value Ec is set in advance as a lower limit of the intermediate link voltage EFC that gradually decreases when the power supplied to the auxiliary power supply 113 is equal to or less than the auxiliary power supply PA.
- the set value Ec is appropriately set in the operation control unit 520 via an input unit (not shown), and the operation control unit 520 may hold data indicating the set value Ec.
- the operation control unit 520 When the input current IS included in the input current signal acquired from the current detector 551 is equal to or less than the set value Ic (second set value), the operation control unit 520 outputs an off operation control signal GC. Thereby, the 1st power converter 111 stops.
- the power regenerated to the overhead line 105 can be estimated from the input current IS. Therefore, the input current IS when the power regenerated to the overhead line 105 becomes the limit value Ps1 is adopted as the set value Ic. Therefore, it becomes a negative value in the present embodiment.
- the set value Ic is appropriately set in the operation control unit 520 via an input unit (not shown), for example, and the operation control unit 520 may hold data indicating the set value Ic. Note that the operation control unit 520 may set the setting value Ic in the operation control unit 520 by calculating the setting value Ic corresponding to the limit value Ps1 input via an input unit (not shown) or the like.
- main conversion apparatus 500 So far, the configuration of main conversion apparatus 500 according to the present embodiment has been described. From here, operation
- main converter 500 operates in the same manner as main converter 100 according to the first embodiment. As a result, the electric vehicle can be accelerated and run at a constant speed.
- the main converter 500 executes an operation control process shown in FIG.
- the operation control unit 520 obtains a regeneration opening command COR indicating that the regeneration of power to the overhead line 105 is restricted from the cab 552 (step S101).
- the figure shows an example in which power regeneration to the overhead line 105 is permitted until time T1. Therefore, in the figure, the intermediate link voltage EFC up to time T1 is substantially constant.
- the operation control unit 520 outputs an ON operation control signal GC. Therefore, the first power conversion unit 111 is operating. For this reason, the input current IS up to time T1 is a positive value because the regenerative power PB generated by the induction motor 103 is smaller than the auxiliary power supply PA, so that the power to be supplied to the auxiliary power supply 113 is from the overhead line 105. It means that it is captured.
- the operation control unit 520 outputs an OFF operation control signal GC in accordance with the regenerative release command COR acquired in step S ⁇ b> 101. Thereby, the operation control unit 520 stops the first power conversion unit 111 (step S102).
- the operation control unit 520 determines whether or not the intermediate link voltage EFC is equal to or lower than the set value Ec by acquiring the EFC signal from the voltage detection unit 114 (step S103).
- the operation control unit 520 When the intermediate link voltage EFC is not equal to or lower than the set value Ec (step S103; No), the operation control unit 520 outputs an off operation control signal GC and continues to stop the first power conversion unit 111 (step S102). .
- the intermediate link voltage EFC gradually decreases because power is no longer taken from the overhead line 105 in a state where the regenerative power PB is smaller than the auxiliary power supply PA as described above.
- the reason why the intermediate link voltage EFC does not drop sharply is that power is supplied from the filter capacitor 115 or the like to the auxiliary power supply device 113. Since the first power conversion unit 111 is stopped, the input current IS is zero.
- step S103 when the intermediate link voltage EFC is equal to or lower than the set value Ec (step S103; Yes), if the intermediate link voltage EFC becomes smaller than the set value Ec, the auxiliary power supply device 113 may stop due to power shortage.
- the operation control unit 520 outputs the ON operation control signal GC to operate the first power conversion unit 111 (step S104).
- the operation control unit 520 determines whether or not the input current IS is larger than the set value Ic by acquiring the input current signal from the current detector 551 (step S105). When the input current IS is larger than the set value Ic (step S105; Yes), the operation control unit 520 outputs the ON operation control signal GC and continues to operate the first power conversion unit 111 (step S104).
- step S105 when the input current IS is equal to or less than the set value Ic (step S105; No), the operation control unit 520 outputs an off operation control signal GC to stop the first power conversion unit 111. (Step S102).
- the first power conversion unit 111 is stopped, so that the input current IS is zero, and power is not regenerated in the overhead line 105.
- the intermediate link voltage EFC is maintained at a constant level because the regenerative power PB is larger than the auxiliary power supply power PA.
- the auxiliary power supply 113 is supplied with electric power that is equal to or higher than the auxiliary power supply PA, the operation of the auxiliary power supply 113 can be stopped. At the same time, it is possible to limit the power regenerated to the overhead line 105 to the limit value Ps1 or less. Furthermore, since the regenerative power generated by the induction motor 103 is supplied to the auxiliary power supply device 113, the power consumption of the electric vehicle can be reduced.
- Modification 3 For example, when the limit value Ps1 is zero, the current detector 551 detects only the current direction, and the operation control unit 520 operates the first power conversion unit 111 based on the detected current direction. And stop may be controlled.
- the operation of the auxiliary power supply device 113 can be prevented from being stopped with a simpler configuration than that of the third embodiment.
- it is possible to limit the power regenerated to the overhead line 105 to the limit value Ps1 ( 0) or less, that is, to prevent the power from being regenerated to the overhead line 105.
- the power consumption of the electric vehicle can be reduced.
- the present invention can be suitably used for a main conversion device mounted on an electric vehicle such as a train or an electric locomotive.
