[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1 As shown, in the first aspect, an embodiment of the present invention provides a feeder self-healing test system based on cloud technology, including a test device 1 and a monitoring device 2.

[0027] The testing device 1 is used to provide simulated fault information to the monitoring device 2 .

[0028] The simulated fault information provided by the test device 1 includes current and voltage analog quantities, input and output signal quantities, and switch open and closed position information.

[0029] The monitoring device 2 includes a power distribution intelligent terminal 21 and a power distribution automation master station system 22; wherein the power distribution intelligent terminal 21 is connected to the power distribution automation master station system 22 and the test device 1 respectively, and is used to isolate the fault area according to the fault detection information provided by the power distribution intelligent terminal 21; and synchronously perform data processing on the simulated fault information to obtain fault detection information. The power distribution automation master station system 22 is used to determine the transfer strategy according to the fault detection information provided by the power distribution intelligent terminal 21, and control the power distribution intelligent terminal 21 to restore the non-fault area based on the transfer strategy.

[0030] In this embodiment, the test device 1 is connected to a cloud platform, and the cloud platform is used to transmit test parameters, test cases and trigger messages provided by the test device 1.

[0031] In another embodiment, the testing device 1 specifically includes a power distribution intelligent tester 11, an analog switch tester 12 and a tester control center 13; the power distribution intelligent tester 11, the analog switch tester 12 and the tester control center 13 are respectively connected to the cloud platform based on pre-configured cloud platform parameters.

[0032] The cloud platform is used to establish a wireless link with the tester control center 13, the power distribution intelligent tester 11 and the analog switch tester 12 and maintain the link status; when the cloud platform receives the simulated fault location of the distribution line transmitted from the tester control center 13, it generates a sequence of signals according to the configuration and sends it to the corresponding power distribution intelligent tester 11 and the analog switch tester 12, and transmits the output results of the power distribution intelligent tester 11 and the analog switch tester 12 to the tester control center 13.

[0033] It can be understood that the tester control center 13 is used to transmit the simulated fault location of the distribution line to the power distribution intelligent tester 11 and the analog switch tester 12, and to check the fault signal and current information simulated by the power distribution intelligent tester 11, and the switch open and closed position information simulated by the analog switch tester 12.

[0034] Correspondingly, the power distribution intelligent tester 11 is used to output fault signals and current information to the power distribution intelligent terminal 21, specifically including voltage and current analog quantities and input and output signal quantities; the analog switch tester 12 is used to output the switch open and closed positions to the power distribution intelligent terminal 21.

[0035] Specifically, a wireless link may be established between the cloud platform and the tester control center 13 , the power distribution intelligent tester 11 , and the analog switch tester 12 through the TCP protocol.

[0036] In this embodiment, the pre-set cloud platform parameters include the ID and password of the wireless link network, the IP address and port number of the cloud platform, the IP address, ID and port number of the power distribution intelligent tester 11, the MAC address, ID and port number of the analog switch tester 12, and the ID and port number of the power distribution intelligent tester 11 and the analog switch tester 12 on the tester control center 13.

[0037] It is understandable that the technicians can configure the cloud platform parameters of the power distribution intelligent tester 11 and the analog switch tester 12 on the tester control center 13 according to the actual test scenario requirements.

[0038] For the monitoring device 2, in one embodiment, the power distribution intelligent tester 11 and the analog switch tester 12 can be connected to the power distribution intelligent terminal 21 through cables respectively; the power distribution intelligent terminal 21 detects corresponding measurement data based on the fault signal and current information simulated by the power distribution intelligent tester 11, and the switch opening and closing position information simulated by the analog switch tester 12, and then sends the measurement data to the distribution automation master station system 22.

[0039] The distribution automation master station system 22 provides a power supply and transfer strategy for fault processing in combination with the processing results of the distribution intelligent terminal 21 .

[0040] Specifically, after receiving the data provided by the power distribution intelligent tester 11 and the analog switch tester 12, the power distribution intelligent terminal 21 first compiles and processes the data, and then transmits the processing results to the power distribution automation master station system 22 through the power protocol.

[0041] Correspondingly, the distribution automation master station system 22 is used to establish an optical fiber or wireless link with the distribution intelligent terminal 21, and is also used to receive the measurement data transmitted by the distribution intelligent terminal 21, and record, analyze and process the measurement data to obtain fault information, fault isolation and recovery methods, and restore non-fault areas through remote control.

[0042] In one embodiment, after the distribution automation master station system 22 analyzes and obtains the fault information, it is also used to display the fault information through a UI interface, so that technical personnel can more intuitively detect the fault test results and handle the fault in a timely manner.

[0043] The embodiment of the present invention forms a test equipment 1 subsystem based on a wireless network through a cloud platform and a tester control center 13, a distribution intelligent tester 11, and an analog switch tester 12, which can be used by testers on the master station side to control the output current, voltage and signal quantity of the distribution intelligent tester 11; at the same time, by forming a monitoring equipment 2 subsystem with a distribution automation master station system 22 and a distribution intelligent terminal 21, it is convenient for personnel on the master station side to check the status of the detection terminal, thereby improving fault testing and processing efficiency.

[0044] Compared with the prior art, the feeder self-healing test system provided in the embodiment of the present invention does not need to pass through the master station. The distribution intelligent terminal 21 can quickly isolate on-site, and can also transmit relevant fault information to the distribution automation master station system 22, and execute the recovery of the non-fault area according to the transfer strategy returned by the distribution automation master station system 22, thereby effectively improving the fault handling efficiency.

[0045] Furthermore, data transmission between various devices and apparatuses in the feeder self-healing test system provided by the present invention is performed through cloud technology or wireless network, so that fault data can be counted more comprehensively and accurately.

[0046] The system or device embodiments described above are merely illustrative, wherein the modules described as separate components may or may not be physically separated, i.e., may be located in one place, or may be distributed on multiple network units.

[0050] On the other hand, the power distribution intelligent tester 11 and the analog switch tester 12 establish a link with the power distribution intelligent terminal 21 through a cable line, preparing to apply analog quantity and signal quantity to the power distribution intelligent terminal 21.

[0051] S2: After the tester control center 13 transmits the distribution line fault location information to the distribution intelligent tester 11 and the analog switch tester 12 in the form of a pulse signal, the distribution intelligent tester 11 and the analog switch tester 12 inject fault parameters into the distribution intelligent terminal 21, and the fault parameters include switch opening information and protection action information.

[0052] S3: After the power distribution intelligent terminal 21 detects the fault parameters output by the power distribution intelligent tester 11 and the analog switch tester 12, it isolates the fault area accordingly and synchronously transmits the processed fault data to the power distribution automation master station system 22.

[0054] Specifically, after the distribution automation master station system 22 completes the data analysis, the analysis information can be displayed through the UI interface.

[0055] The above-mentioned distribution automation master station system 22 and the distribution intelligent terminal 21 can form a monitoring system. When conducting master station side testing, the tester can deploy the tester control center 13 to the terminal device and place the terminal device next to the distribution automation master station system 22, so as to quickly view the fault handling results generated by the distribution automation master station system 22 while triggering the test case.

[0056] The above-mentioned embodiment transmits messages between the tester control center 13 and the power distribution intelligent tester 11 and the analog switch tester 12 through the cloud platform, and at the same time transmits messages between the power distribution automation master station system 22 and the power distribution intelligent terminal 21 through optical fiber or wireless network, so as to realize the local isolation of the power distribution automation master station system 22 and the power distribution intelligent terminal 21, and obtain the corresponding non-fault area recovery plan, thereby effectively shortening the system fault processing time, improving system reliability, and facilitating maintenance work for technical personnel.

[0057] In another embodiment, after completing S1, the following steps are performed:

[0058] S12: The tester control center 13 downloads and triggers the test case to the cloud platform, and forwards the test case and related trigger information to the power distribution intelligent tester 11 and the analog switch tester 12 through the cloud platform.

[0059] S13: The power distribution intelligent tester 11 and the analog switch tester 12 output current and voltage analog quantities and input and output control quantities to the power distribution intelligent terminal 21 based on the test case.

[0060] S14: After the power distribution intelligent terminal 21 receives the output data provided by the power distribution intelligent tester 11 and the analog switch tester 12, it isolates the fault according to the output data, processes the output data and sends the processed data to the distribution automation master station system 22.

[0061] S15: After receiving the data sent by the power distribution intelligent terminal 21, the power distribution automation master station system 22 further processes the data to obtain the power transfer strategy for the non-fault area, and sends the power transfer strategy to the power distribution intelligent terminal 21 so that the power distribution intelligent terminal 21 executes the power transfer strategy.

[0062] In a third aspect, the present invention provides a data processing device, comprising a processor, wherein the processor is coupled to a memory, the memory stores a program, and the program is executed by the processor, so that the data processing device executes the test method of the feeder self-healing test system based on cloud technology described in the second aspect.
