[0017] A further solution is that when the CPU control module collects the voltage and current of the opening, closing and energy storage interface output of the distribution terminal through the voltage and current acquisition module, the detected voltage and current are compared with the UI=W of the waveform data. When the two are not equal, the digital-to-analog conversion module is adjusted to output the analog quantity to control the power element, so that the distribution terminal outputs the opening, closing and energy storage interface voltage and current, which is a closed-loop control equal to the UI=W of the waveform data, so as to achieve the purpose of analog control of the fault switch of the distribution terminal.

[0029] In this embodiment, the voltage and current acquisition module is used to collect the voltage and current signals of the opening and closing of the current distribution terminal and the energy storage output interface, and transmit the voltage and current signals to the CPU control module for processing.

[0030] In this embodiment, the waveform recording module is used to record the waveform data of the voltage and current of the opening, closing, and energy storage output interface of the current distribution terminal, and upload the waveform data to the CPU control module.

[0031] When the test is completed, the console reads the recording file of the distribution terminal through the IEC104 protocol, and reads the recording file obtained by the recording module from the CPU control module for similarity analysis. The analysis result is compared with the preset accuracy to determine whether it meets the qualification standards. The console also receives the sudden telesignaling signal of the distribution terminal through the IEC104 protocol, and compares it with the preset telesignaling signal to determine whether it meets the qualification standards.

[0032] Specifically, the device for dynamically reversible electronic load and simulating energy storage characteristics of high-voltage switch opening and closing provided by the present invention specifically includes a console of the upper computer part, a switch fault waveform library, a CPU control module of the lower computer part, a digital-to-analog conversion module, a power element, a switch output module, a voltage flow acquisition module, and a wave recording module, etc. Among them, the console is mainly responsible for receiving the switch fault waveform imported by the upper computer, saving it to the switch fault waveform library, and sending the waveform data to the CPU control module. After the test is completed, the wave recording file of the distribution terminal is read through the IEC104 protocol, and the wave recording file obtained by the CPU control module is read to perform similarity analysis. The analysis result is compared with the preset accuracy to determine whether it is qualified or not, and the sudden telesignal of the distribution terminal is received through the IEC104 protocol, and compared with the preset telesignal signal that should be sent to determine whether it is qualified or not.

[0033] Among them, the switch fault waveform library is mainly responsible for saving the abnormal waveform files of high-voltage switch opening and closing energy storage imported by the console or read; the CPU control module is mainly responsible for receiving the waveform data sent by the console, and outputting the data to the digital-to-analog conversion module in real time to read the current voltage and current data of the voltage and current acquisition module in real time, and reading the waveform data of the recording module after the test is completed and uploading it to the console; the digital-to-analog conversion module is mainly responsible for receiving the data output by the CPU control module, and outputting the analog quantity to control the power element; the power element is mainly responsible for controlling the load current of the opening, closing and storage output interface of the distribution terminal according to the analog quantity output by the digital-to-analog conversion module; the switch output module is mainly responsible for converting the digital signal sent by the CPU control module into the analog switch position of the opening, closing or energy storage position signal and outputting it to the distribution terminal for input detection; the voltage and current acquisition module is mainly responsible for collecting the voltage and current of the opening, closing and energy storage output interface of the current distribution terminal, and transmitting the voltage and current data to the CPU control module for processing; the recording module is mainly responsible for recording the waveform data of the voltage and current of the opening, closing and energy storage output interface of the current distribution terminal, and transmitting the waveform data to the CPU control module for analysis after the test.

[0034] Specifically, the switch fault waveform library of this embodiment is a folder on the PC side, which contains multiple cfg and DAT files. These two files are waveform files in a standard COMTRADE1999 format. The files come from the recording module, which records the opening circuit voltage, opening circuit current, closing circuit voltage, closing circuit current, energy storage circuit voltage, energy storage circuit current, switch position of the primary switch, etc. of the faulty switch, and are data streams collected at a sampling rate of 50K.

[0035] Specifically, the recording module of this embodiment is used to record the current controller's opening circuit voltage, opening circuit current, closing circuit voltage, closing circuit current, energy storage circuit voltage, and energy storage circuit current, and transmit them to the CPU control module in the form of data stream to finally generate a waveform file in the COMTRADE1999 format for this test on the console.

[0036] Embodiment of a test method for simulating a high-voltage switch device based on a dynamic reversible electronic load:

[0037] The device is applied to the above-mentioned dynamic reversible electronic load-based high-voltage switch device simulation. The method includes: saving the switch fault waveform data imported by the host computer to the switch fault waveform library. When the test starts, the host computer sends the waveform data to the CPU control module.

[0038] The upper computer controls the distribution terminal to output opening, closing, and energy storage commands through the IEC104 protocol, outputs the opening, closing, and energy storage voltages at the distribution terminal, the wave recording module starts real-time wave recording, and the voltage and current acquisition module starts to collect the voltage of the current distribution terminal output opening, closing, and energy storage interface and transmits it to the CPU control module.

[0039] The CPU control module controls the switch output module according to the waveform data sent by the host computer.

[0040] The CPU control module controls the digital-to-analog conversion module according to the waveform data sent by the host computer. The digital-to-analog conversion module outputs analog quantity to control the power element, so that the distribution terminal outputs opening and closing, and the energy storage interface is loaded.

[0041] The CPU control module collects the voltage and current of the opening, closing and energy storage interface output of the distribution terminal through the voltage and current acquisition module, and outputs the analog quantity to control the power element through the digital-to-analog conversion module.

[0042] In this embodiment, when the test process is completed, the real-time recording of the recording module is completed, the console reads the recording file of the recording module through the CPU control module, reads the recording file of the distribution terminal through the IEC104 protocol, reads the switch abnormality telesignal sent by the distribution terminal through the IEC104 protocol, and outputs the test results according to the read data.

[0043] In this embodiment, when the CPU control module collects the voltage and current of the opening, closing, and energy storage interface output of the distribution terminal through the voltage and current acquisition module, the detected voltage and current are compared with the UI=W of the waveform data. When the two are not equal, the digital-to-analog conversion module is adjusted to output the analog quantity to control the power element, so that the distribution terminal outputs the opening, closing, and energy storage interface voltage and current, and a closed-loop control is equal to the UI=W of the waveform data, so as to achieve the purpose of analog control of the fault switch of the distribution terminal.

[0044] In this embodiment, the test results are output based on the read data, including: performing a similarity analysis on the recording file of the recording module and the recording file of the distribution terminal, and comparing them with a preset accuracy percentage to detect whether the recording function and performance of the distribution terminal meet the requirements; performing a similarity analysis on the voltage and current data stream of the recording file of the recording module and the voltage and current and switch quantity data stream of the switch fault waveform data, and comparing them with a preset accuracy percentage to detect whether the load capacity of the distribution terminal meets the requirements.

[0045] It also includes judging whether the switch abnormality telesignal sent by the distribution terminal is the same as the preset switch abnormality telesignal, so as to detect whether the switch fault status analyzed by the distribution terminal meets the requirements.

[0046] In actual applications, the switch fault waveform imported by the host computer is saved in the switch fault waveform library. When the test starts, the host computer sends the waveform data to the CPU control module. When the test is completed, the host computer controls the distribution terminal to output the opening, closing and energy storage commands through the IEC104 protocol.

[0047] When the distribution terminal outputs the opening, closing and energy storage voltages, the recording module starts real-time recording, and the voltage and current acquisition module starts to collect the voltages of the opening, closing and energy storage interfaces output by the current distribution terminal and transmits them to the CPU control module. The CPU control module controls the switch output module according to the waveform data sent by the host computer, and the CPU control module controls the digital-to-analog conversion module according to the waveform data sent by the host computer. The digital-to-analog conversion module outputs analog quantity to control the power element, and enables the distribution terminal to output the opening, closing and energy storage interfaces to be loaded, and the load size is output in a fixed power manner according to the waveform data UI=W.

[0048] Then, the CPU control module collects the voltage and current of the power distribution terminal output opening, closing, and energy storage interface through the voltage and current acquisition module for calculation, such as U*I, and compares it with the UI=W of the waveform data. When the two W are not equal, the digital-to-analog conversion module is adjusted, and the analog quantity output by the digital-to-analog conversion module controls the power element, so that the power distribution terminal outputs the opening, closing, and energy storage interface voltage*current, and the closed-loop control is equal to the UI=W of the waveform data, so as to achieve the purpose of the power distribution terminal simulating the control of the fault switch. Since the U and I of the waveform data change every 20us, the U and I compared every 20us will change once, thereby achieving the effect of the dynamic change of the power distribution terminal simulating the control of the fault switch.

[0049] When the U and I data streams of the waveform data are output, that is, the test process is over, the real-time recording of the recording module is completed, and the console reads the recording file of the recording module through the CPU control module, reads the distribution terminal recording file through the IEC104 protocol, and reads the switch abnormality telesignal sent by the distribution terminal through the IEC104 protocol.

[0050] Therefore, the result judgment of this embodiment includes: performing similarity analysis on the recording file of the recording module and the recording file of the distribution terminal, comparing them with the preset accuracy percentage, and detecting whether the recording function and performance of the distribution terminal meet the requirements.

[0051] The U*I data stream of the recording file of the recording module is analyzed for similarity with the I*U and switch quantity data streams of the switch fault waveform, and compared with the preset accuracy percentage to detect whether the load capacity of the distribution terminal meets the requirements.

[0052] Whether the switch abnormality telesignal sent by the distribution terminal is the same as the preset switch abnormality telesignal, and whether the distribution terminal analyzes the switch fault status to meet the requirements.

[0053] Specifically, the similarity analysis of this embodiment includes the following steps:

[0054] Step 1, waveform alignment. Since the time when this device starts recording is definitely not the same as the time when the distribution terminal starts recording, alignment is required. The alignment method is to detect the sudden change position when the voltage data or current data suddenly doubles from a value and record the time stamp. Then find the sudden change position of the same channel of the distribution terminal and record the time stamp, which is expressed as: the time stamp of this device - the time stamp of the distribution terminal = the time stamp at which the device can start similarity analysis.

[0055] Step 2, similarity analysis, error = ((BP) / B)*100, where B is the device, P is the distribution terminal, and the control console has a preset error value. All data starting from the time-stamp data that can be used for similarity analysis (opening circuit voltage, opening circuit current, closing circuit voltage, closing circuit current, energy storage circuit voltage, energy storage circuit current) are compared. After all comparisons are completed, if they are less than the preset error value, they are qualified.

[0056] In this embodiment, the judgment conditions for detecting whether the fault status of the distribution terminal analysis switch meets the requirements include: the waveform of the abnormal switch fault in the current test playback is "energy storage circuit breakage", and the console presets that the distribution terminal must send a "energy storage circuit breakage" telesignal after the test is completed. When the telesignal signal is sent after the test is completed, it is qualified.

[0057] It can be seen that the present invention first records various fault action waveform data of the 10Kv high-voltage switch through a recording device, and the waveform data includes voltage, current, and switch position information, and imports the waveform information into the present device. The present invention communicates with the distribution terminal through the standard IEC104 protocol, and sends the opening / closing / energy storage command to the distribution terminal, and the distribution terminal executes the output opening / closing / energy storage action. The present invention will dynamically adjust the load current according to the imported waveform information, so as to achieve the purpose of simulating the operation of the distribution terminal with various faults of the 10Kv high-voltage primary switch, and read the waveform file recorded by the distribution terminal through the standard IEC104 protocol. The waveform file recorded by the distribution terminal is compared with the waveform file recorded by the present device for similarity, and the remote signal analyzed by the distribution terminal received through the standard IEC104 protocol is compared with the preset switch fault type. After comparing the results, it is judged whether it is qualified or not and a test report is generated.

[0058] Therefore, the present invention can be widely used in the production and development of distribution automation terminals, standardize the functions and performance of the terminals, and fill the gap in the standard detection methods. For the distribution terminals specified by the state, the state monitoring and recording functions of the 10Kv high-voltage switch opening and closing, energy storage circuit, and various fault states of the high-voltage switch can be automatically detected by the instrument.

[0059] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
