Description

Technical Field

[0001] The present invention belongs to the technical field of air separation treatment, and particularly relates to a method and device for producing and treating electronic special gases with on-site self-power supply. Background Art

[0002] In electronic special gas research centers and laboratories, the demand for high-purity nitrogen as a packaging gas source is extremely urgent. The prior art solution CN202023214052.9 "A purifier for processing electronic special gases" gives a purification treatment solution for nitrogen.

[0003] However, the above technical solutions often make the traditional nitrogen production method rely on a centralized gas supply system, resulting in problems such as high transportation costs and poor gas supply flexibility. At the same time, these systems usually require an external stable mains power supply, and it is difficult to meet the usage requirements for some remote areas or places with unstable power supply. Therefore, it is of great significance to develop a technology that can supply power on-site and flexibly produce high-purity nitrogen.

[0004] In view of the above technical problems, specifically, the present application provides a method and device for producing and treating electronic special gases with on-site self-power supply. Summary of the Invention

[0005] To achieve the object of the present invention, the present invention adopts the following technical solutions:

[0006] In the first aspect, the present application provides a method for producing and treating electronic special gases with on-site self-power supply, specifically including:

[0007] S1 Based on the remaining capacity of the energy storage device and the load prediction data of the photovoltaic device for the remaining time period of the current date, determine the deviation situation of the nitrogen production data at different time periods under different similar power generation dates, and use the deviation situation to determine the production deviation time periods under different similar power generation dates;

[0008] S2 Determine the data belonging to the production deviation time periods in different time periods under different similar power generation dates, and combine the deviation situation of the nitrogen production data in different production deviation time periods. When it is determined that nitrogen production treatment can be carried out in the current time period, proceed to the next step;

[0009] S3 When it is determined that the deviation situation of the nitrogen production data when directly supplying power to the nitrogen production equipment by the photovoltaic device in the current time period does not meet the requirements according to the load prediction data of the current time period, proceed to the next step;

[0010] S4 Determine the fluctuation situation of the load prediction data of the current time period, and combine the deviation situation between the load prediction data and the rated load of the gas compression module of the nitrogen production equipment to determine the power supply treatment strategy of the nitrogen production equipment, and use the nitrogen production equipment to carry out nitrogen production treatment.

[0011] The beneficial effects of the present invention are as follows:

[0012] According to the load prediction data of the current period, it is determined whether the deviation situation of the nitrogen production data meets the requirements when directly supplying power to the nitrogen production equipment by using the photovoltaic device in the current period, thus avoiding the technical problem that the purity and production amount of nitrogen production do not meet the requirements caused by directly supplying power to the nitrogen production equipment by using the photovoltaic device, and also laying a foundation for generating a differential power supply processing strategy according to the difference of the load prediction data, ensuring the reliability of the nitrogen production process.

[0013] Based on the fluctuation situation of the load prediction data of the current period and the deviation situation between the load prediction data and the rated load of the gas compression module of the nitrogen production equipment, the power supply processing strategy of the nitrogen production equipment is determined. It not only considers the influence on the service life when supplying power to the energy storage device due to the fluctuation situation of the load prediction data, but also considers the difference in the power supply matching degree with the gas compression module due to the deviation situation from the rated load of the gas compression module, realizing the determination of the power supply processing strategy from multiple perspectives, reducing the influence on the service life of the energy storage device, and at the same time ensuring the reliability of the power supply processing of the gas compression module.

[0014] A further technical solution is that the load prediction data of the photovoltaic device is determined according to the light intensity of different periods of the current date.

[0015] A further technical solution is that the similar power generation date is a historical date in which the deviation amount of the load prediction data of the photovoltaic device in different periods from the current date is within a preset deviation amount range.

[0016] A further technical solution is that the deviation situation of the nitrogen production data is determined according to the nitrogen production amount and the purity of nitrogen production at different times.

[0017] A further technical solution is that the method for determining the production deviation period under the similar power generation date is as follows:

[0018] Based on the nitrogen production data in the period, determine the nitrogen production amount and the purity of nitrogen production at different times in the period;

[0019] Use the nitrogen production amount and the purity of nitrogen production to determine the nitrogen production deviation time in the time;

[0020] According to the proportion of the number of nitrogen production deviation times in the period, determine whether the period is a production deviation period.

[0021] A further technical solution lies in that the deviation time for nitrogen production is the time when either the nitrogen production amount or the purity of the nitrogen production does not meet the requirements.

[0022] In a second aspect, the present invention provides an on-site self-powered electronic special gas production device, which adopts the above-mentioned on-site self-powered electronic special gas production method, and specifically includes:

[0023] An energy supply module, a gas compression module, and a gas production module;

[0024] Among them, the energy supply module includes an energy storage device and a photovoltaic device, and is used for the energy supply processing of the gas compression module and the gas production module;

[0025] The gas compression module is responsible for compressing the raw gas and transporting it to the gas production module;

[0026] The gas production module is responsible for using the vacuum pressure swing adsorption process to separate nitrogen from the compressed raw gas by adsorbing and desorbing the gas at different pressures.

[0027] A further technical solution lies in that the photovoltaic device has a three-dimensional structure, and a single-axis or double-axis tracking system is used on the fixing structure of the photovoltaic panel of the photovoltaic device, so that the photovoltaic panel can rotate with the change of the sunlight direction.

[0028] A further technical solution lies in that the gas compression module is built using a low-power compressor with a rated power less than a preset power threshold.

[0037] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this specification. Obviously, the described embodiments are only a part of the embodiments of this specification, rather than all the embodiments. Based on the embodiments of this specification, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this specification.

[0038] In electronic special gas research centers and laboratories, the demand for high-purity nitrogen as a packaging gas source is extremely urgent. Traditional nitrogen production methods often rely on centralized gas supply systems, which have problems such as high transportation costs and poor gas supply flexibility. At the same time, these systems usually require an external stable commercial power supply, and it is difficult to meet the usage requirements for some remote areas or places with unstable power supply. Therefore, it is of great significance to develop a technology that can be self-powered on-site and flexibly produce high-purity nitrogen.

[0039] One of the on-site direct power supply electronic special gas production and processing devices includes the following:

[0040] Energy supply module: Adopt a three-dimensional expandable photovoltaic device. The photovoltaic panel combines high-efficiency solar cell technologies such as PERC and HJT to improve the power generation efficiency. The battery panel has a three-dimensional structure, can maximize the reception of solar energy in a limited space, and can be expanded according to actual needs to further increase the light-receiving area. A single-axis or double-axis tracking system is used on the fixed structure of the photovoltaic panel, so that the photovoltaic panel can rotate with the change of the sunlight direction, increasing the sunlight absorption efficiency. Its advantage is that it can adapt to different site conditions and energy requirements, efficiently collect solar energy and convert it into electrical energy in sunny conditions, and provide stable power support for the entire production system. At the same time, an additional lithium battery pack is added as an energy storage device, and a fast-charging lithium battery pack is used. The purpose of this module is to maintain the long-term energy supply when the nitrogen production device is working, be able to quickly charge the battery, and enhance the versatility. The additional battery pack is designed as a detachable module and is equipped with additional spare parts for convenient transportation and replacement.

[0041] Gas compression module: A low-power compressor is selected. Since this system is powered by solar energy + battery pack, the low-power compressor can better match the power supply capacity of the photovoltaic device, reduce energy consumption while ensuring the gas compression effect. It preliminarily compresses raw materials such as air to prepare for the subsequent vacuum pressure swing adsorption process.

[0042] Gas production module: The vacuum pressure swing adsorption process is used. By adsorbing and desorbing gases at different pressures, nitrogen in the compressed raw material gas is separated. This process can effectively remove impurities and finally produce nitrogen with a purity of up to 99.9999%, meeting the strict requirements of electronic special gas research and laboratories for high-purity packaging gas sources.

[0043] Advantages of system construction: The entire production system has the characteristic of being mobile and can be set up on-site. Each module is designed compactly, facilitating transportation and installation. It can be quickly set up on-site according to the actual site and requirements to achieve on-site nitrogen production without relying on complex external infrastructure.

[0044] When any one of the total nitrogen production amount and the average purity of nitrogen production in the period does not meet the requirements, the period is determined as a production deviation period.

[0045] Based on the data of the production deviation periods in different similar power generation dates in different periods, determine the proportion of the number of dates belonging to the production deviation periods in different similar power generation dates in different periods, and use the proportion of the number of dates to determine the concerned deviation periods in the periods, obtain the deviation situation of the nitrogen production data in the concerned deviation periods corresponding to the production deviation periods, determine the average purity of nitrogen production in different corresponding production deviation periods. When the number of concerned deviation periods with the average purity of nitrogen production in different corresponding production deviation periods less than the preset purity setting value is greater than the preset number of concerned deviation periods, it is determined that nitrogen production cannot be carried out in the current period.

[0046] Take the historical periods in which the deviation amounts of the load prediction data at different times in the current period all meet the requirements as reference periods. Use the deviation situation of the nitrogen production data when directly supplying power to the nitrogen production equipment by the photovoltaic device in the reference periods to determine the average purity and nitrogen production amount of nitrogen production in different reference periods. When the average purity and nitrogen production amount of nitrogen production in different reference periods are both within the preset range, it is determined that the deviation situation of the nitrogen production data when directly supplying power to the nitrogen production equipment by the photovoltaic device in the current period meets the requirements.

[0047] Based on the fluctuation of the load prediction data in the current period, determine the change amount of the load prediction data between different moments in the current period, and use the proportion of the moments whose change amount is not within the preset change interval to determine the charging influence coefficient of the energy storage device in the current period;

[0048] Based on the deviation between the load prediction data and the rated load of the gas compression module of the nitrogen production equipment, determine the proportion of the moments when the deviation between the load prediction data and the rated load of the gas compression module of the nitrogen production equipment is not within the preset load deviation amount interval, and use it as the matching deviation coefficient of the gas compression module;

[0049] Based on the ratio of the charging influence coefficient to the matching deviation coefficient, determine the load matching coefficient of the load prediction data. When the load matching coefficient is less than the preset matching coefficient threshold, use the energy storage device to supply power to the nitrogen production equipment, and use the electric energy of the photovoltaic device for the charging process of the energy storage device. When the load matching coefficient is not less than the preset matching coefficient threshold, use the photovoltaic device to supply power to the gas compression module, and use the energy storage device to supply power to other modules except the gas compression module.

[0050] Example 1 is as Figure 1 shown. The present application provides a method for on-site self-powered electronic special gas production and treatment, which specifically includes:

[0051] S1 Based on the remaining capacity of the energy storage device and the load prediction data of the photovoltaic device in the remaining period of the current date, determine the deviation of the nitrogen production data in different periods under different similar power generation dates, and use the deviation to determine the production deviation periods under different similar power generation dates;

[0052] Further, the load prediction data of the photovoltaic device is determined according to the light intensity in different periods of the current date

[0053] It should be noted that the similar power generation date is a historical date whose deviation amount of the load prediction data of the photovoltaic device in different periods is within the preset deviation amount interval compared with the current date.

[0054] It can be understood that the deviation of the nitrogen production data is determined according to the nitrogen production amount and the purity of nitrogen production at different moments.

[0055] Specifically, as Figure 2 shown, the method for determining the production deviation period under the similar power generation date is:

[0056] Based on the nitrogen production data in the period, determine the nitrogen production amount and the purity of nitrogen production at different moments in the period;

[0057] Determine the nitrogen production deviation time among the said moments by using the amount of nitrogen production and the purity of nitrogen production;

[0058] Determine whether the said time period is a production deviation time period according to the proportion of the number of nitrogen production deviation times in the said time period.

[0059] Furthermore, the nitrogen production deviation time is the moment when any one of the nitrogen production amount and the purity of nitrogen production does not meet the requirements.

[0060] It can be understood that when the proportion of the number of nitrogen production deviation times in the said time period is greater than the preset proportion of the number of times, it is determined that the said time period is a production deviation time period.

[0061] Optionally, the method for determining the production deviation time period under the similar power generation date is as follows:

[0062] Based on the nitrogen production data in the said time period, determine the nitrogen production amount and the purity of nitrogen production at different moments in the said time period;

[0063] Based on the nitrogen production amount and the purity of nitrogen production at different moments, determine the total amount of nitrogen production and the average purity of nitrogen production in the said time period;

[0064] Determine whether the said time period is a production deviation time period according to the total amount of nitrogen production and the average purity of nitrogen production in the said time period.

[0065] Furthermore, when any one of the total amount of nitrogen production and the average purity of nitrogen production in the said time period does not meet the requirements, it is determined that the said time period is a production deviation time period.

[0066] Optionally, the method for determining the production deviation time period under the similar power generation date is as follows:

[0067] Based on the nitrogen production data in the said time period, determine the nitrogen production amount and the purity of nitrogen production at different moments in the said time period. Based on the nitrogen production amount and the purity of nitrogen production at different moments, determine the total amount of nitrogen production and the average purity of nitrogen production in the said time period. When any one of the total amount of nitrogen production and the average purity of nitrogen production in the said time period does not meet the requirements, it is determined that the said time period is a production deviation time period;

[0068] When both the total amount of nitrogen production and the average purity of nitrogen production in the said time period meet the requirements:

[0069] Based on the purity of nitrogen production at different moments, determine the amount of nitrogen production with the purity of nitrogen production in the said time period less than the preset purity threshold. When the amount of nitrogen production with the purity of nitrogen production in the said time period less than the preset purity threshold does not meet the requirements, it is determined that the said time period is a production deviation time period;

[0070] When the amount of nitrogen production with a purity less than the preset purity threshold during the time period meets the requirements:

[0071] Using the amount of nitrogen production and the purity of nitrogen production, when it is determined that there is no nitrogen production deviation moment at the moment, it is determined that the time period does not belong to the production deviation time period;

[0072] When there is a nitrogen production deviation moment at the moment:

[0073] Obtain the proportion of the number of nitrogen production deviation moments. When the proportion of the number of nitrogen production deviation moments does not meet the requirements, it is determined that the time period belongs to the production deviation time period;

[0074] When the proportion of the number of nitrogen production deviation moments meets the requirements:

[0075] According to the deviation amount between the nitrogen production amount of different nitrogen production deviation moments and the preset nitrogen production amount, and the deviation amount between the purity of nitrogen production and the preset purity threshold, determine the nitrogen production deviation coefficient of different nitrogen production deviation moments. When the number of nitrogen production deviation moments with a nitrogen production deviation coefficient greater than the preset deviation coefficient threshold does not meet the requirements, it is determined that the time period belongs to the production deviation time period;

[0076] When the number of nitrogen production deviation moments with a nitrogen production deviation coefficient greater than the preset deviation coefficient threshold meets the requirements:

[0077] Obtain the total amount of nitrogen production and the average purity of nitrogen production, and combine the nitrogen production deviation coefficients of different nitrogen production deviation moments to determine the production anomaly value of the time period, and use the production anomaly value to determine whether the time period is a production deviation time period.

[0078] Optionally, when the production anomaly value of the time period is greater than the preset production anomaly threshold, it is determined that the time period is a production deviation time period.

[0079] S2 Determine the data belonging to the production deviation time period in different similar power generation dates for different time periods, and combine the deviation conditions of the nitrogen production data of different production deviation time periods. When it is determined that nitrogen production treatment can be carried out in the current time period, proceed to the next step;

[0080] Specifically, as Figure 3 shown, determining that nitrogen production treatment can be carried out in the current time period specifically includes:

[0081] Using the data belonging to the production deviation time period in different similar power generation dates for different time periods, determine the proportion of the number of dates belonging to the production deviation time period in different similar power generation dates for different time periods, and use the proportion of the number of dates to determine the concerned deviation time period in the time period;

[0082] Obtain the deviation situation of the nitrogen production data in the corresponding production deviation period of the concerned deviation period, and determine the average purity of nitrogen production in different corresponding production deviation periods;

[0083] Based on the average value of the average purity of nitrogen production in different corresponding production deviation periods for each concerned deviation period, determine whether nitrogen production treatment can be carried out in the current period.

[0084] Further, the concerned deviation period is a period in which the proportion of the number of dates is greater than the set value of the proportion of the number.

[0085] It should be noted that determining whether nitrogen production treatment can be carried out in the current period based on the average value of the average purity of nitrogen production in different corresponding production deviation periods for each concerned deviation period specifically includes:

[0086] When the number of concerned deviation periods in which the average value of the average purity of nitrogen production in different corresponding production deviation periods is less than the preset purity set value is greater than the preset number of concerned deviation periods, it is determined that nitrogen production treatment cannot be carried out in the current period.

[0087] Further, when nitrogen production treatment cannot be carried out in the current period, the energy storage device is charged using a photovoltaic device.

[0088] In another possible embodiment, determining that nitrogen production treatment can be carried out in the current period specifically includes:

[0089] Using the data belonging to the production deviation period in different similar power generation dates for different periods, determine the proportion of the number of dates belonging to the production deviation period in different similar power generation dates for different periods, and use the proportion of the number of dates to determine the abnormal weight coefficient for different periods;

[0090] Obtain the deviation situation of the nitrogen production data in the corresponding production deviation period of the concerned deviation period, determine the average purity of nitrogen production in different corresponding production deviation periods, and determine the production deviation coefficient for different periods according to the average value of the average purity of nitrogen production in different corresponding production deviation periods;

[0091] Using the sum of the products of the abnormal weight coefficients and the production deviation coefficients for different periods, determine the comprehensive production deviation coefficient, and use the comprehensive production deviation coefficient to determine whether nitrogen production treatment can be carried out in the current period.

[0092] Further, when the comprehensive production deviation coefficient is greater than the preset production deviation coefficient threshold, it is determined that nitrogen production treatment cannot be carried out in the current period.

[0093] Optionally, it is determined that nitrogen production treatment can be carried out in the current period, specifically including:

[0094] Obtain the proportion of the number of production deviation periods in different similar power generation dates. When the average value of the proportion of the number of production deviation periods in different similar power generation dates does not meet the requirements, it is determined that nitrogen production treatment cannot be carried out in the current period;

[0095] When the average value of the proportion of the number of production deviation periods in different similar power generation dates meets the requirements:

[0096] Determine the similar power generation dates with the proportion of the number of production deviation periods not meeting the requirements as production deviation dates. When the number of the production deviation dates does not meet the requirements, it is determined that nitrogen production treatment cannot be carried out in the current period;

[0097] When the number of the production deviation dates meets the requirements:

[0098] Based on the data of different periods belonging to production deviation periods in different similar power generation dates, determine the proportion of the number of dates in which different periods belong to production deviation periods in different similar power generation dates, and use the proportion of the number of dates to determine the abnormal weight coefficient of different periods. When the abnormal weight coefficients of different periods all meet the requirements, it is determined that nitrogen production treatment can be carried out in the current period;

[0099] When there are periods with abnormal weight coefficients not meeting the requirements:

[0100] Obtain the number of periods with abnormal weight coefficients not meeting the requirements. When the number of periods with abnormal weight coefficients not meeting the requirements is greater than the preset abnormal period number threshold, it is determined that nitrogen production treatment cannot be carried out in the current period;

[0101] When the number of periods with abnormal weight coefficients not meeting the requirements is not greater than the preset abnormal period number threshold:

[0102] Obtain the deviation situation of the nitrogen production data of the concerned deviation period in the corresponding production deviation period, determine the average purity of nitrogen production in different corresponding production deviation periods, and determine the production deviation coefficient of different periods according to the average value of the average purity of nitrogen production in different corresponding production deviation periods;

[0103] Determine the comprehensive production deviation coefficient based on the sum of the products of the abnormal weight coefficients and the production deviation coefficients of different periods, and use the comprehensive production deviation coefficient to determine whether nitrogen production treatment can be carried out in the current period.

[0104] When the deviation of the nitrogen production data when directly powering the nitrogen production equipment with the photovoltaic device in the current period does not meet the requirements according to the load prediction data of the current period, proceed to the next step;

[0105] Specifically, determining that the deviation of the nitrogen production data when directly powering the nitrogen production equipment with the photovoltaic device in the current period does not meet the requirements specifically includes:

[0106] Regarding the historical period in which the deviation amounts of the load prediction data at different times in the current period all meet the requirements as the reference period;

[0107] Using the deviation situation of the nitrogen production data when directly powering the nitrogen production equipment with the photovoltaic device in the reference period to determine the average nitrogen production purity and nitrogen production volume in different reference periods;

[0108] Based on the average nitrogen production purity and nitrogen production volume in different reference periods, determining whether the deviation situation of the nitrogen production data when directly powering the nitrogen production equipment with the photovoltaic device in the current period meets the requirements.

[0109] Furthermore, when the average nitrogen production purity and nitrogen production volume in different reference periods are both within the preset range, it is determined that the deviation situation of the nitrogen production data when directly powering the nitrogen production equipment with the photovoltaic device in the current period meets the requirements.

[0110] It should be noted that when the deviation situation of the nitrogen production data when directly powering the nitrogen production equipment with the photovoltaic device in the current period meets the requirements, directly power the nitrogen production equipment with the photovoltaic device in the current period.

[0111] It can be understood that determining that the deviation situation of the nitrogen production data when directly powering the nitrogen production equipment with the photovoltaic device in the current period does not meet the requirements specifically includes:

[0112] S31 Regarding the historical period in which the deviation amounts of the load prediction data at different times in the current period all meet the requirements as the reference period;

[0113] S32 Using the deviation situation of the nitrogen production data when directly powering the nitrogen production equipment with the photovoltaic device in the reference period to determine the nitrogen production purity and nitrogen production volume at different times in different reference periods, and using the deviation amount between the nitrogen production purity at different times and the preset nitrogen production volume and the deviation amount between the nitrogen production purity and the preset purity threshold to determine the nitrogen production deviation amount of different reference periods;

[0114] S33 determines the comprehensive production deviation based on the nitrogen production deviations in different reference periods, and uses the comprehensive production deviation to determine whether the deviation of the nitrogen production data meets the requirements when directly supplying power to the nitrogen production equipment using the photovoltaic device in the current period.

[0115] Further, the comprehensive production deviation is the average value of the nitrogen production deviations in different reference periods.

[0116] In addition, it should be noted that when the comprehensive production deviation is within the preset deviation range, it is determined that the deviation of the nitrogen production data does not meet the requirements when directly supplying power to the nitrogen production equipment using the photovoltaic device in the current period.

[0117] Optionally, the above step S31 includes the following content:

[0118] S311 uses the historical periods in which the deviation amounts of the load prediction data at different moments in the current period all meet the requirements as reference periods. Based on the average nitrogen production purity and nitrogen production volume in different reference periods, when there is any reference period in which the average nitrogen production purity or the nitrogen production volume does not meet the requirements, it proceeds to step S312. When the average nitrogen production purity and the nitrogen production volume in different reference periods both meet the requirements, it proceeds to step S313;

[0119] S312 uses the reference period in which either the average nitrogen production purity or the nitrogen production volume does not meet the requirements as the screening deviation reference period. When the number of screening deviation reference periods does not meet the requirements, it is determined that the deviation of the nitrogen production data does not meet the requirements when directly supplying power to the nitrogen production equipment using the photovoltaic device in the current period. When the number of screening deviation reference periods meets the requirements, it proceeds to step S313;

[0120] S313 determines the nitrogen production reliability coefficients for different reference periods based on the average nitrogen production purity and nitrogen production volume in different reference periods. When the average value of the nitrogen production reliability coefficients for different reference periods does not meet the requirements, it is determined that the deviation of the nitrogen production data does not meet the requirements when directly supplying power to the nitrogen production equipment using the photovoltaic device in the current period. When the average value of the nitrogen production reliability coefficients for different reference periods meets the requirements, it proceeds to step S32.

[0121] Optionally, the above step S32 includes the following content:

[0122] S321 determines the nitrogen production purity and nitrogen production amount at different moments in different reference periods by using the deviation of nitrogen production data during the power supply process of the nitrogen production equipment directly using a photovoltaic device in the reference period, and determines the nitrogen production deviation amount of different reference periods by using the deviation amount between the nitrogen production purity at different moments and the preset nitrogen production amount, and the deviation amount between the purity of nitrogen production and the preset purity threshold;

[0123] S322 When there is a reference period in which the nitrogen production deviation amount does not meet the requirements, it is determined that the deviation of the nitrogen production data during the power supply process of the nitrogen production equipment directly using a photovoltaic device in the current period does not meet the requirements. When there is no reference period in which the nitrogen production deviation amount does not meet the requirements, it proceeds to step S323;

[0124] S323 uses the reference periods in which the nitrogen production deviation amount is within the preset production deviation amount range as suspected production deviation periods. When there are no suspected production deviation periods, it is determined that the deviation of the nitrogen production data during the power supply process of the nitrogen production equipment directly using a photovoltaic device in the current period meets the requirements. When there are suspected production deviation periods, it proceeds to step S324;

[0125] S324 When the number of suspected production deviation periods is greater than the preset number threshold of production deviation periods, it is determined that the deviation of the nitrogen production data during the power supply process of the nitrogen production equipment directly using a photovoltaic device in the current period does not meet the requirements. When the number of suspected production deviation periods is not greater than the preset number threshold of production deviation periods, it proceeds to step S33.

[0126] S4 determines the fluctuation of the load prediction data in the current period, and combines the deviation between the load prediction data and the rated load of the gas compression module of the nitrogen production equipment to determine the power supply processing strategy of the nitrogen production equipment, and uses the nitrogen production equipment to carry out nitrogen production processing.

[0127] Furthermore, the fluctuation of the load prediction data includes the change amount of the load prediction data between different adjacent moments.

[0128] Specifically, as Figure 4 shown, the method for determining the power supply processing strategy of the nitrogen production equipment is:

[0129] Based on the fluctuation of the load prediction data in the current period, determine the change amount of the load prediction data between different moments in the current period, and use the proportion of the moments whose change amount is not within the preset change range to determine the charging influence coefficient of the energy storage device in the current period;

[0130] Determine the proportion of the time when the deviation between the load prediction data and the rated load of the gas compression module of the nitrogen production equipment is not within the preset load deviation range based on the deviation between the load prediction data and the rated load of the gas compression module of the nitrogen production equipment, and use it as the matching deviation coefficient of the gas compression module;

[0131] Based on the ratio of the charging influence coefficient to the matching deviation coefficient, determine the load matching coefficient of the load prediction data, and use the load matching coefficient to determine the power supply processing strategy of the nitrogen production equipment.

[0132] Further, using the load matching coefficient to determine the power supply processing strategy of the nitrogen production equipment specifically includes:

[0133] When the load matching coefficient is less than the preset matching coefficient threshold, use the energy storage device to supply power to the nitrogen production equipment, and use the electric energy of the photovoltaic device for the charging process of the energy storage device;

[0134] When the load matching coefficient is not less than the preset matching coefficient threshold, use the photovoltaic device to supply power to the gas compression module, and use the energy storage device to supply power to other modules except the gas compression module.

[0135] In the second aspect of Embodiment 2, as Figure 5 shown, the present invention provides an on-site self-powered electronic special gas production device, adopting the above-mentioned on-site self-powered electronic special gas production method, specifically including:
