Description

Technical Field

[0001] This application relates to the technical field of oil chromatograph device calibration, and particularly to a method and system for controlling the autonomous implementation of on-site calibration of oil chromatograph devices. Background Art

[0002] Oil chromatograph on-line monitoring devices are widely used in power systems to monitor the concentration and change trend of dissolved gases in transformer oil in real time, so as to achieve early warning and diagnosis of internal faults of transformers. In order to ensure the accuracy and operation stability of the devices, on-site calibration work needs to be carried out regularly on the devices. The traditional on-site calibration of oil chromatograph devices mainly relies on manual operation, and the accuracy of the devices is evaluated by comparing the data between a laboratory gas chromatograph and the on-line monitoring device. However, this method has many problems.

[0003] The traditional manual calibration process mainly includes the preparation of standard oil samples, on-site sampling and detection, data comparison and analysis, and device calibration and adjustment. First, standard oil samples with different concentrations are manually prepared and their concentrations are ensured to be stable. Then, the standard oil samples are connected to the oil chromatograph on-line monitoring device for detection, and at the same time, standard data is obtained using a laboratory gas chromatograph. Next, the detection data of the two are compared, the error is calculated, and the accuracy of the device is evaluated. If the error exceeds the allowable range, the device parameters need to be manually adjusted and re-calibrated until the requirements are met. Finally, the data is manually recorded to generate a calibration report and archived. However, this process has problems such as time-consuming and laborious, poor data consistency, inability to provide real-time feedback, and low efficiency, and it is difficult to meet the calibration requirements of a large number of on-line monitoring devices.

[0024] Currently, the traditional manual verification process mainly includes the preparation of standard oil samples, on-site sampling and detection, data comparison and analysis, and device calibration and adjustment. First, standard oil samples with different concentrations are manually prepared and their concentrations are ensured to be stable. Then, the standard oil samples are connected to the on-line oil chromatograph monitoring device for detection, and at the same time, standard data is obtained using a laboratory gas chromatograph. Next, the detection data of the two are compared, the error is calculated, and the accuracy of the device is evaluated. If the error exceeds the allowable range, the device parameters need to be manually adjusted and re-verified until the requirements are met. Finally, the data is manually recorded to generate a verification report and archived. However, this process has problems such as time-consuming and laborious, poor data consistency, inability to provide real-time feedback, and low efficiency, and it is difficult to meet the verification requirements of large-scale on-line monitoring devices.

[0025] Specifically, the defects and deficiencies of the prior art are mainly as follows: 1. Complex manual operation: On-site verification requires professional personnel to perform complex operations, including the preparation of standard oil samples, sampling, detection, and data comparison and analysis, which are time-consuming and laborious and prone to errors.

[0026] 2. Low verification efficiency: Manual verification cannot achieve a continuous and rapid verification process, and it is difficult to meet the verification requirements of large-scale on-line monitoring devices, resulting in a long verification cycle and inability to detect device deviations and failures in a timely manner.

[0027] 3. Poor data consistency: Due to the instability of manual operations, different times and different personnel operations may lead to large differences in verification results, affecting the reliability of verification results.

[0028] 4. Unable to monitor in real time: The traditional verification method cannot monitor the operating status and data deviation of the on-line monitoring device in real time, and it is difficult to achieve dynamic calibration and optimization of the device.

[0029] Based on this, the inventor proposes a method for controlling the autonomous implementation of on-site verification of oil chromatographic devices to monitor the operating status and data deviation of on-line monitoring devices in real time, and to achieve dynamic calibration and optimization of the devices. The method and system will be further described through multiple embodiments below.

[0030] Please refer to Figure 1 and Figure 2 , Figure 1 which shows a flowchart of a method for controlling the autonomous implementation of on-site verification of an oil chromatographic device provided in this embodiment; Figure 2 which shows some of the hardware devices corresponding to the method for controlling the autonomous implementation of on-site verification of an oil chromatographic device provided in this embodiment.

[0031] As Figure 1 and Figure 2 shown, this embodiment provides a method for controlling the autonomous implementation of on-site verification of an oil chromatographic device, including: Step S10: In response to a standard oil sample preparation instruction, mix a blank oil sample with a standard gas based on the standard concentration data of a preset oil sample to obtain the standard oil sample; In some embodiments, the instruction can be generated by an electronic device with data processing capabilities. For example, in the field of computers, an instruction is an operation command executed by a CPU. The electronic device includes but is not limited to desktop computers, laptop computers, and embedded electronic devices, etc. The specific model specifications of these electronic devices can be reasonably selected according to actual needs and will not be elaborated here.

[0032] In some embodiments, as combined with Figure 2 shown, for the hardware corresponding to the method provided in this embodiment, it includes an oil storage tank 211, a pressure gauge 212, a booster pump 213, a circulation pump 214, an electric valve 215, a booster controller 221, a circulation controller 222, a valve controller 223, and a data processing unit 231. The pressure gauge 212 is connected to the oil storage tank 211 through a pipeline, and the connection is located in the top area on the side of the oil storage tank. The booster pump 213 is connected to the oil storage tank 211 through a pipeline, and the connection is located in the upper-middle position on the side of the oil storage tank. The circulation pump 214 and the oil storage tank 213 are connected by two one-way pipelines, and the connection is located in the lower-middle part of the oil storage tank. The electric valve 215 is connected to the oil storage tank 211 through a one-way pipeline, and the connection is located at the bottom of the oil storage tank. The booster controller 221 is separately connected to the pressure gauge 212 and the booster pump 213 through circuits. The circulation controller 222 is connected to the circulation pump 214 through a circuit.

[0033] Optionally, the valve controller 223 is connected to the electric valve 215 through a circuit. The data processing unit 231 is separately connected to the booster controller 221, the circulation controller 222, and the valve controller 223 through circuits.

[0034] Optionally, the storage oil tank 211 is made of corrosion-resistant inert material and can store insulating oil for a long time without reacting with it.

[0035] Optionally, the pressure gauge 212 is a gas pressure gauge, which can measure the gas pressure in the tank in real time and transmit the air pressure data to the booster controller.

[0036] Optionally, the booster pump 213 is controlled by the booster controller 221 and can increase the pressure of the gas in the tank or maintain the air pressure.

[0037] Optionally, the circulation pump 214 is controlled by the circulation controller 222. After being turned on through two one-way liquid pipelines, it can make the liquid fully mix and dissolve quickly with the gas in the tank.

[0038] Optionally, the electric valve 215 is controlled by the valve controller 223. After being opened, it can unidirectionally transport the oil sample in the storage oil tank 211 to the oil chromatograph device 232 (on-line monitoring device for dissolved gases in oil).

[0039] Optionally, the booster controller 221, the circulation controller 222, and the valve controller 223 are all single-function electronic components with stable and reliable performance.

[0040] It should be noted that for the booster controller 221, the circulation controller 222, the valve controller 223, and for the blank insulating oil and the standard gas for gas chromatography when introduced into the storage oil tank, it can be controlled by an electronic device. Exemplarily, after responding to the standard oil sample preparation instruction, it can control the blank insulating oil and the standard gas for gas chromatography to be introduced into the storage oil tank, and turn on relevant components such as the booster pump 213 and the circulation pump 214 according to the program.

[0041] It should also be noted that for the storage oil tank 211, the pressure gauge 212, the booster pump 213, the circulation pump 214, the electric valve 215, the booster controller 221, the circulation controller 222, the valve controller 223, and the data processing unit 231, In some embodiments, according to the standard concentration data, determine the volume or mass ratio of at least seven component gases included in the blank oil sample and the standard gas. According to the ratio, mix and dissolve the blank oil sample and the standard gas under a pressurized state to obtain the standard oil sample.

[0042] Optionally, the step of mixing and dissolving the blank oil sample and the standard gas under a pressurized state according to the ratio to obtain the standard oil sample includes: Obtain the pressure data value of the blank oil sample and the standard gas mixed dissolution environment every first preset time; judge whether the pressure data value is greater than a preset pressure threshold every second preset time. If so, generate the oil sample transfer instruction, and the oil sample transfer instruction is used to control the opening and closing of the electric valves of the storage tank and the oil chromatograph device.

[0043] It should be noted that the first preset time and the second preset time can be 100 milliseconds or 1 second. When monitoring whether the collected pressure data value is greater than the preset pressure threshold, it can be considered that the blank oil sample and the standard gas are fully mixed and dissolved.

[0044] It should also be noted that the dissolved gas in oil refers to the gas dissolved in oil in molecular state. Under normal circumstances, the oil / paper insulation material inside the oil-filled electrical equipment will gradually age and decompose under the action of heat and electricity, generating a small amount of various small molecule hydrocarbons and characteristic gases such as carbon monoxide and carbon dioxide. If there are latent faults such as overheating or discharge inside the oil-filled equipment, the generation rate of these characteristic gases will be accelerated. When the gas generation rate is slow and the gas production volume is small, most of the gas is dissolved in the oil. The change in the content of the dissolved characteristic gas in the oil is closely related to the degree of development and type of the fault inside the electrical equipment. At present, using the dissolved gas in oil analysis technology is one of the most effective means to detect latent faults inside the oil-filled equipment.

[0045] In order to calibrate the oil chromatograph device, a standard oil sample is prepared by mixing a blank oil sample and a standard gas based on the standard concentration data of the preset oil sample. For the seven component gases, it mainly includes gases such as H2, C2H2, CO, CO2, CH4, and C2H4. During the mixing process, the specific ratio can be selected according to actual needs.

[0046] Step S20: In response to the oil sample transfer instruction, transfer the standard oil sample to the oil chromatograph device to analyze the gas content dissolved in the standard oil sample, and obtain the monitored concentration data of the standard oil sample; In some embodiments, for the on-line monitoring device of dissolved gas in oil, there are mainly off-line or on-line oil chromatograph devices. Among them, for the monitoring unit of the on-line monitoring device, there are mainly: Oil-gas separation unit: Oil-gas separation is a key process, and the level of oil-gas separation efficiency will directly affect the accuracy of the test results. The current mainstream oil-gas separation methods are generally vacuum degassing method, headspace degassing method and membrane permeation method.

[0047] Gas component separation unit: After the dissolved gases in oil are separated from the oil, a chromatographic column is usually used to separate various gas components according to a certain sample retention time. Detection unit: According to the different characteristics of the removed gas components, different gas detectors are selected to convert the concentration of the gas components into an electrical signal for detection. Conventional detection methods include chromatographic detector method, array sensor method, infrared spectroscopy method, and photoacoustic spectroscopy method.

[0048] It should be noted that after the standard oil sample is prepared according to the preset concentration, by controlling the opening of the electric valve 215 between the oil storage tank 211 and the oil chromatograph 232 oil circuit, the standard oil sample enters the oil chromatograph 232 from the oil storage tank 211. Exemplarily, when the pressure gauge value is monitored to reach the preset value, the electric valve is opened, and the standard oil sample enters the oil chromatograph under positive pressure through the pipeline. Step S30: Determine the concentration deviation value of the oil sample according to the monitored concentration data and the standard concentration data. In some embodiments, when the standard oil sample is transmitted to the oil chromatograph 232 for calibration, the calibration work starts. During this process, the control module monitors the operation status of the device in real time. If parameter anomalies are sent, audible and visual alarms will be issued. After the monitoring is completed, the monitored concentration data and the standard concentration data are subtracted to determine the concentration deviation value of the oil sample.

[0049] Optionally, according to the monitored concentration data and the standard concentration data, a test report is generated, and the test report is sent to the mobile terminal device based on the wireless network and displayed based on the mobile terminal device.

[0050] Step S40: Generate a calibration optimization instruction according to the concentration deviation value and the preset concentration range value, and respond to the calibration optimization instruction to dynamically calibrate and optimize the parameters of the oil chromatograph.

[0051] In some embodiments, the obtained concentration deviation value is automatically compared with the preset concentration range value. If the error is large, remote monitoring of the calibration process is achieved through network connection, and the calibration data and results are viewed in real time; and the detection data of the on-line monitoring device is automatically compared with the laboratory standard data. Once it is found that the data deviation exceeds the preset range or anomalies occur during the calibration process (such as unstable oil sample concentration, device detection unit failure, etc.), an alarm will be immediately issued and the problem details will be recorded.

[0052] Optionally, the real-time operation status parameters of the oil chromatograph calibration process are collected every third preset time. According to the operation status parameters, it is judged whether the detection unit of the oil chromatograph fails; if so, an alarm control instruction is generated and the problem details information of the corresponding detection unit of the oil chromatograph is recorded.

[0053] It should be noted that the third preset time can be 100 milliseconds or 1 second. The operating state parameters during the real-time calibration process of the oil chromatograph device are collected in real time through sensors, and the specific time interval is selected according to actual requirements.
