[0025] An embodiment, the generator set 211 is connected with the first circuit breaker 21 through the first disconnector 23, and the power supply end is connected with the second circuit breaker 22 through the second disconnector 24; the generator set 211 is connected with the first disconnector 23 through the first voltage transformer 28 and the first current transformer 25, the power supply end is connected with the second disconnector 24 through the second voltage transformer 29 and the second current transformer 26, and the load end is connected with the third voltage transformer 210; the third voltage transformer 210 is connected with the third current transformer 27, and the first circuit breaker 21 and the second circuit breaker 22 are connected with the third current transformer 27; the first voltage transformer 28, the first current transformer 25, the third voltage transformer 210 and the third current transformer 27 are connected with the unit controller 15; the second voltage transformer 29, the second current transformer 26, the first voltage transformer 28 and the first current transformer 25 are connected with the grid-connected controller 14.

[0026] Specifically, Figure 2TV1 is the first voltage transformer 28, CT1 is the first current transformer 25, QS1 is the first disconnector 23, QF1 is the first circuit breaker 21, TV2 is the second voltage transformer 29, CT2 is the second current transformer 26, QS2 is the second disconnector 24, QF2 is the second circuit breaker 22, TV3 is the third voltage transformer 210, CT3 is the third current transformer 27, load output is the load end, and mains output is the mains end; The first voltage transformer 28 and the first current transformer 25 are used to detect the voltage and current values generated by the generator set 211, the first disconnector 23 is used to isolate the generator set 211 during maintenance, and the first circuit breaker 21 is used to control and protect the power output of the generator set 211. The second voltage transformer 29 and the second current transformer 26 are used to detect the voltage and current values of the mains end, the second disconnector 24 is used to isolate the mains end during maintenance, and the second circuit breaker 22 is used to control and protect the mains end. The third voltage transformer 210 and the third current transformer 27 are used to detect the current and voltage of the load end.

[0027] When the mobile power supply vehicle is operating alone, i.e., the mobile power supply vehicle is supplying power to the load alone. The power output of the generator set 211 is controlled by QS1 and QF1 to supply power to the load. First, connect the cable between the load output and the load, close QS1, and issue the ignition command of the generator set 211 through the application program on the industrial panel 11. At this time, the generator set 211 starts, and after the speed of the generator set 211 on the industrial panel 11 reaches the preset rated speed, click the application program circuit breaker QF1 closing instruction on the industrial panel 11. The closing instruction is received and issued to the PLC controller 13 through the wireless local area network via the wireless router 12. The PLC controller 13 issues the control instruction to the unit controller 15 through the 485 bus. After receiving the closing instruction, the unit controller 15 controls the QF1 closing relay to be powered on to close. At this time, QF1 is closed, the power of the generator set 211 is transmitted to the load end, and the power supply to the load is completed. The voltage and current value signals detected by TV1, CT1, TV3, and CT3 are sent to the unit controller 15. The unit controller 15 transmits the detected voltage and current signals to the industrial panel 11 through the bus via the wireless router 12. The power, voltage, and current of the generator set 211 can be monitored in real time on the industrial panel 11, and the real-time power, voltage, and current of the load can also be detected in real time.

[0028] When the mobile power supply vehicle stops supplying power to the load, only the application on the industrial tablet 11 needs to click the breaker QF1 tripping command, the signal transmission process is similar to the closing process, and the QF1 tripping relay of the unit controller 15 is powered on to make QF1 trip, and finally click the extinguishing command to control the generator set 211 to extinguish.

[0029] When the mobile power supply vehicle operates independently and is connected to the grid, uninterrupted operation can be realized, and the user at the load end has "zero awareness". In order to realize this process, first connect the load output cable and the power output cable, close QS1, press the generator set 211 ignition command on the application program on the industrial tablet 11 to start the generator set 211, select the "disconnection / grid connection" option on the application program on the industrial tablet 11 as "grid connection" mode, and then click the breaker QF1 closing instruction on the application program on the industrial tablet 11. When the unit controller 15 receives the closing command, the unit controller 15 performs quasi-synchronization judgment through the detected TV3, CT3, TV1 and CT1. When the voltage and current on one side of the generator set 211 and the load end are synchronized, the QF1 closing relay of the unit controller 15 is powered on, QF1 is closed, and then the base load on the unit controller 15 is adjusted to the existing load on the application program on the industrial tablet 11. At this time, the generator set 211 and the grid supply power to the load at the same time, and then the grid switch on the grid is disconnected, realizing that the generator set 211 independently supplies power to the load. Thus, the mobile power supply vehicle completes a grid connection operation. Finally, the "disconnection / grid connection" mode selection button on the application program on the industrial tablet 11 is selected as "disconnection" mode.

[0030] When the mobile power supply vehicle needs to perform secondary grid connection operation, that is, after the grid is repaired, the grid side needs to be put into operation again to supply power to the load, and the mobile power supply vehicle exits the power supply; This process is based on the single machine grid connection operation of the power supply vehicle. In order to realize this process, first close QS2, select the "disconnection / grid connection" option on the application program on the industrial tablet 11 as "grid connection" mode, and then click the breaker QF2 closing command on the application program on the industrial tablet 11. When the grid connection controller 14 receives the closing command, the grid connection controller 14 performs quasi-synchronization judgment through the detected TV2, CT2, TV1 and CT1. When the voltage and current on one side of the grid and the load end are synchronized, the QF2 closing relay of the grid connection controller 14 is powered on, QF2 is closed, and the grid switch on the grid is closed. At this time, the generator set 211 and the grid supply power to the load at the same time, and then the base load on the application program on the industrial tablet 11 is adjusted to zero. At this time, the load is completely transferred to the grid power supply, and then QF1 and QF2 are tripped by clicking the QF1 breaker tripping command and the QF2 breaker tripping command on the application program on the industrial tablet 11 respectively, completing the secondary grid connection operation. Finally, the generator set 211 is extinguished by the extinguishing command on the application program on the industrial tablet 11.

[0031] The mobile power supply vehicle of the present application can issue control instructions to the mobile power supply vehicle through the input mechanism 11 under a Wi-Fi network environment, and the control instructions are sent to the unit controller 15 and the grid-connected controller 14 of the mobile power supply vehicle through the network, so that remote control of the mobile power supply vehicle and real-time monitoring of the state parameters of the generator set 211 can be realized, without the need for on-site operation, so that the operator can be away from the dangerous operation environment, thereby effectively improving the safety and comfort of the operation of the power supply vehicle in some harsh working scenarios.
