Description

Technical Field

[0001] This application relates to the field of air compressors, and in particular to a method and system for the distribution and operation of a group of air compressors. Background Technology

[0002] Air compressors are core auxiliary equipment in power plant operation, primarily providing stable compressed air for various systems to support the safe and efficient operation of the power plant. For example, they provide clean, dry, and pressure-stable compressed air for precision instruments such as pneumatic valves and pressure transmitters in distributed control systems (DCS). They are also mainly used to transport coal ash and dust collected by economizers, air preheaters, and electrostatic precipitators.

[0003] As the demand for compressed air in power plants gradually increases, a single air compressor cannot meet the growing needs. Therefore, power plants typically construct air compressor clusters consisting of several air compressors to generate sufficient compressed air. Since economizers, air preheaters, and dust collectors all require compressed air for removing coal ash and dust, but the number of air compressors is relatively large, accurately determining the appropriate number and type of air compressors to meet the specific requirements of each unit becomes a challenge. Summary of the Invention

[0004] In order to accurately determine the air compressors that meet the needs of the economizer, air preheater and dust collector and the appropriate number of air compressors, this application provides an air compressor group allocation and operation method and system.

The number of air compressors corresponding to the economizer ash hopper, air preheater ash hopper, and dust collector ash hopper is determined based on the first ash storage capacity, the second ash storage capacity, and the third ash storage capacity. Obtain the last soot blowing time point for each of the economizer ash hopper, air preheater ash hopper, and dust collector ash hopper, and determine the time interval from the last soot blowing time point for each of the economizer ash hopper, air preheater ash hopper, and dust collector ash hopper to the current time.

The operating status value of each air compressor is determined based on the discharge pressure change curve and continuous working time of each air compressor.

Obtaining the last soot blowing time of the economizer ash hopper, etc., allows for the determination of the time interval from the last soot blowing to the current time. The corresponding ash storage capacity and time interval are key factors characterizing the ash volume change and growth of the economizer ash hopper, etc. Therefore, based on the ash storage capacity and time interval of each component such as the economizer ash hopper, the corresponding importance can be accurately determined. The higher the importance, the more air compressors in good working condition are needed for soot blowing. The exhaust pressure change curve and continuous working time are key factors characterizing the working condition of the air compressor.

Additionally, the character " / " in this article, unless otherwise specified, generally indicates that the preceding and following related objects have an "or" relationship.

[0029] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.

[0030] This application provides a method for allocating and operating an air compressor group, executed by an electronic device. This electronic device can be a server or a terminal device. The server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smartphone, tablet, laptop, desktop computer, etc., but is not limited to these. The terminal device and the server can be directly or indirectly connected via wired or wireless communication. This application does not impose any limitations on this. Figure 1 As shown, the method includes steps S101, S102, S103, S104, S105, and S106, wherein, S101, obtain the exhaust pressure change curve of each air compressor, the continuous working time of each air compressor, the first ash storage capacity of the economizer ash hopper, the second ash storage capacity of the air preheater ash hopper, and the third ash storage capacity of the dust collector ash hopper.

[0031] In this embodiment, operators can pre-install pressure sensors at the compressed air output port of each air compressor to collect the compressed air pressure output by each compressor. Electronic devices are connected to the pressure sensors of each air compressor via wires, enabling the acquisition of the compressed air pressure output by each compressor and generating an exhaust pressure change curve for each compressor—a pressure-time curve. The electronic devices are also connected to each air compressor via wires. When an air compressor starts, it sends a notification signal to the electronic device, informing it that the compressor has started. The electronic device can then determine the continuous operating time of each air compressor based on its start-up time and the current time.

[0032] During operation, the economizer, air preheater, and dust collector collect coal ash and dust from flue gas and air, storing them in ash hoppers. The air preheater is short for air preheater. Level sensors can be pre-installed in the economizer, air preheater, and dust collector ash hoppers to collect the ash level, from which the ash storage capacity can be determined. Electronic equipment is connected to the level sensors in these hoppers via wires to obtain the ash level in each hopper, thus determining the first, second, and third ash storage capacities. Each economizer, air preheater, and dust collector may have more than one ash hopper; the ash storage capacity for each hopper can then be calculated based on its respective ash level. In other embodiments, the ash hoppers may be conical. Due to the different cross-sectional areas of cones, the increase in ash storage capacity may not be linear with the linear increase in ash level. Therefore, operators can pre-set the corresponding ash storage capacity for different ash levels based on the shape of the ash hopper.

[0033] S102, based on the first ash storage capacity, the second ash storage capacity, and the third ash storage capacity, determine the number of air compressors corresponding to the economizer ash hopper, the air preheater ash hopper, and the dust collector ash hopper.

[0034] In the embodiments of this application, the larger the ash storage capacity, the more air compressors are required to achieve smooth and rapid ash conveying. Therefore, the electronic equipment can accurately determine the appropriate number of air compressors corresponding to the economizer ash hopper and other components based on the first ash storage capacity, the second ash storage capacity, and the third ash storage capacity.

[0035] S103, obtain the last soot blowing time point corresponding to each of the economizer ash hopper, air preheater ash hopper and dust collector ash hopper, and determine the time interval from the last soot blowing time point corresponding to each of the economizer ash hopper, air preheater ash hopper and dust collector ash hopper to the current time.

[0036] In this embodiment, the operator can store the time of each soot blowing operation in an electronic device for recording. Therefore, the electronic device obtains the last soot blowing time of each component, such as the economizer ash hopper, and then calculates the time interval since the last soot blowing based on the current time. A longer time interval indicates a longer period without soot blowing, potentially resulting in a larger ash accumulation and a higher level of importance.

[0037] S104. The importance of the economizer ash hopper, air preheater ash hopper and dust collector ash hopper is determined based on the first ash storage capacity of the economizer ash hopper, the second ash storage capacity of the air preheater ash hopper, the third ash storage capacity of the dust collector ash hopper and their respective time intervals.

[0038] In the embodiments of this application, a larger ash storage capacity indicates a higher necessity for soot blowing, and a longer time interval may also indicate a higher necessity for soot blowing. Therefore, ash storage capacity and time interval are key factors affecting the importance of the economizer ash hopper, air preheater ash hopper, and dust collector ash hopper. Electronic equipment can accurately determine the corresponding importance of each based on its respective ash storage capacity and time interval. A higher importance indicates a higher necessity for soot blowing. In order to perform soot blowing more effectively, an air compressor in good working condition is needed to perform soot blowing operations on the more important components.

[0039] S105 determines the operating status value of each air compressor based on the exhaust pressure change curve and continuous operating time of each air compressor.

[0040] In the embodiments of this application, the exhaust pressure change curve of the air compressor records the change of compressed air discharged by the air compressor over time. The longer the continuous working time, the greater the possibility of unstable air supply of the air compressor. Therefore, the exhaust pressure change curve and the continuous working time are key factors affecting the working state of the air compressor. Thus, the electronic equipment can accurately determine the working state value of each air compressor based on the exhaust pressure change curve and the continuous working time of each air compressor.

[0041] S106. Based on the number of air compressors corresponding to the economizer ash hopper, air preheater ash hopper, and dust collector ash hopper, the importance of each air compressor, and the working status value of each air compressor, determine the corresponding target air compressor.

[0042] In the embodiments of this application, after the electronic device determines the required number of air compressors, their respective importance, and the working status value of each air compressor corresponding to the economizer ash hopper, air preheater ash hopper, and dust collector ash hopper, it can accurately determine the target air compressors that meet the needs of each of the economizer ash hopper, air preheater ash hopper, and dust collector ash hopper by comprehensively analyzing the above factors.

[0043] One possible implementation of this application embodiment involves determining the relative importance of the economizer ash hopper, air preheater ash hopper, and dust collector ash hopper in step S104 based on the first ash storage capacity of the economizer ash hopper, the second ash storage capacity of the air preheater ash hopper, the third ash storage capacity of the dust collector ash hopper, and their respective time intervals. Specifically, this includes steps S1031 (not shown in the figure), S1032 (not shown in the figure), S1033 (not shown in the figure), and S1034 (not shown in the figure). S1031, determine the first ratio of the first ash storage amount to the first preset storage amount, determine the second ratio of the second ash storage amount to the second preset storage amount, and determine the third ratio of the third ash storage amount to the third preset storage amount.

[0044] In this embodiment, the electronic device stores the total capacity of all ash hoppers corresponding to the economizer, air preheater, and dust collector. The first preset storage capacity is the total capacity of the economizer ash hopper, the second preset storage capacity is the total capacity of the air preheater ash hopper, and the third preset storage capacity is the total capacity of the dust collector ash hopper. The electronic device divides the first ash storage capacity by the first preset storage capacity to obtain a first ratio representing the current ash amount in the economizer ash hopper relative to the total capacity. A higher first ratio indicates a larger amount of ash collected by the economizer, requiring more soot blowing, and correspondingly, a higher level of importance. The electronic device can determine the second ratio for the air preheater ash hopper and the third ratio for the dust collector ash hopper in the same manner, which will not be elaborated further here.

[0045] S1032, the importance of the economizer ash hopper is determined based on the first ratio, the first ash storage amount of the economizer ash hopper, and the corresponding time interval.

[0046] In summary, for the embodiments of this application, the first ratio, the first ash storage capacity, and the time interval from the last soot blowing operation to the present time are all key factors affecting the importance of the economizer ash hopper. Therefore, the electronic device can accurately determine the importance of the economizer ash hopper by comprehensively analyzing the first ratio, the first ash storage capacity, and the corresponding time interval.

[0047] S1033, the importance of the air preheater ash hopper is determined based on the second ratio, the second ash storage capacity of the air preheater ash hopper, and the corresponding time interval.

[0048] In summary, for the embodiments of this application, the second ratio, the second ash storage capacity, and the time interval from the last soot blowing operation to the current time are all key factors affecting the importance of the air preheater ash hopper. Therefore, the electronic equipment can accurately determine the importance of the air preheater ash hopper by comprehensively analyzing the second ratio, the second ash storage capacity, and the corresponding time interval.

[0049] S1034, the importance of the dust collector hopper is determined based on the third ratio, the third ash storage capacity of the dust collector hopper, and the corresponding time interval.

[0050] In summary, for the embodiments of this application, the third ratio, the third ash storage capacity, and the time interval from the last soot blowing operation to the present time are all key factors affecting the dust collector ash hopper. Therefore, the electronic equipment can accurately determine the importance of the dust collector ash hopper by comprehensively analyzing the third ratio, the third ash storage capacity, and the corresponding time interval.

[0051] One possible implementation of this application embodiment involves determining the importance of the economizer ash hopper based on a first ratio, the first ash storage capacity of the economizer ash hopper, and the corresponding time interval in steps S1032, S1033, and S1034; determining the importance of the air preheater ash hopper based on a second ratio, the second ash storage capacity of the air preheater ash hopper, and the corresponding time interval; and determining the importance of the dust collector ash hopper based on a third ratio, the third ash storage capacity of the dust collector ash hopper, and the corresponding time interval. Specifically, this includes steps one, two, and three. Step 1: Determine the ratio of the first ash storage amount to the corresponding time interval to obtain the first growth rate of the economizer ash hopper. Based on the first ratio, the first growth rate, and their respective weights, determine the importance of the economizer ash hopper.

[0052] In this embodiment of the application, the time interval can be in days or hours. The electronic device determines the first growth rate of ash in the economizer ash hopper by dividing the first ash storage amount by the corresponding time interval. A larger first growth rate indicates a faster increase in ash, necessitating more soot blowing to remove coal ash and dust from the hopper; therefore, a larger first growth rate corresponds to a higher level of importance. A larger first ratio indicates that the economizer ash hopper is close to its total capacity limit, requiring more soot blowing to remove coal ash and dust; a larger first ratio corresponds to a higher level of importance. In summary, both the first ratio and the first growth rate are key factors affecting importance. Staff can set the weights of the first ratio and the first growth rate according to needs and actual conditions. For example, the weight of the first ratio can be 0.7 and the weight of the first growth rate can be 0.3. Then, the corresponding weights are stored in the electronic device. The electronic device normalizes the first ratio and the first growth rate of the economizer ash hopper to obtain the corresponding normalized data. The electronic device calls the respective weights to perform a weighted calculation on the normalized data to obtain a value. This value can accurately represent the importance of the economizer ash hopper.

[0053] Step 2: Determine the ratio of the second ash storage capacity to the corresponding time interval to obtain the second growth rate of the air preheater ash hopper. Based on the second ratio, the second growth rate, and their respective weights, determine the importance of the air preheater ash hopper.

[0054] In this embodiment, the electronic device determines the second growth rate of ash in the air preheater ash hopper by dividing the second ash storage amount by the corresponding time interval. A larger second growth rate indicates a faster increase in ash, necessitating soot blowing to remove coal ash and dust from the hopper; therefore, a larger second growth rate corresponds to a higher level of importance. A larger second ratio indicates that the ash hopper is close to its total capacity limit, requiring more soot blowing to remove coal ash and dust; again, a larger second ratio corresponds to a higher level of importance. In summary, both the second ratio and the second growth rate are key factors influencing importance. Operators can set the weights corresponding to the second ratio and the second growth rate according to needs and actual conditions, for example, a weight of 0.7 for the second ratio and 0.3 for the second growth rate. These weights are then stored in the electronic device. The electronic device normalizes the second ratio and the second growth rate of the air preheater ash hopper to obtain normalized data. The electronic device then uses the respective weights to perform a weighted calculation on the normalized data to obtain a value that accurately characterizes the importance of the air preheater ash hopper.

[0055] Step 3: Determine the ratio of the third ash storage capacity to the corresponding time interval to obtain the third growth rate of the dust collector ash hopper. Based on the third ratio, the third growth rate, and their respective weights, determine the importance of the dust collector ash hopper.

[0056] In this embodiment, the electronic device determines the third growth rate of ash in the dust collector hopper by dividing the third ash storage amount by the corresponding time interval. A larger third growth rate indicates a faster increase in ash, necessitating more soot blowing to remove coal ash and dust from the hopper; therefore, a larger third growth rate corresponds to a higher level of importance. A larger third ratio indicates that the hopper is close to its total capacity limit, requiring more soot blowing to remove coal ash and dust; again, a larger third ratio corresponds to a higher level of importance. In summary, both the third ratio and the third growth rate are key factors influencing importance. Operators can set weights for each of the third ratio and the third growth rate according to needs and actual conditions, for example, a weight of 0.7 for the third ratio and 0.3 for the third growth rate. These weights are then stored in the electronic device. The electronic device normalizes the third ratio and the third growth rate of the dust collector hopper to obtain normalized data. The electronic device then uses the respective weights to perform a weighted calculation on the normalized data to obtain a value that accurately characterizes the importance of the dust collector hopper.

[0057] One possible implementation of this application embodiment involves determining the number of air compressors corresponding to the economizer ash hopper, air preheater ash hopper, and dust collector ash hopper in step S102 based on the first ash storage capacity, the second ash storage capacity, and the third ash storage capacity. This specifically includes steps S1021 (not shown in the figure), S1022 (not shown in the figure), S1023 (not shown in the figure), and S1024 (not shown in the figure). S1021, determine the first ratio of the first ash storage amount to the first preset storage amount, determine the second ratio of the second ash storage amount to the second preset storage amount, and determine the third ratio of the third ash storage amount to the third preset storage amount.

[0058] For the embodiments of this application, this step can be specifically referred to the content disclosed in step S1031, and will not be repeated here.

[0059] S1022, determine the sum of the first ratio, the second ratio, and the third ratio.

[0060] For the embodiments of this application, it is assumed that the first ratio is 1 / 3, the second ratio is 1 / 4, and the third ratio is 1 / 2. The electronic device sums the above three ratios to obtain a total of 1 / 3 + 1 / 4 + 1 / 2 = 13 / 12. The electronic device calculates this total to facilitate the subsequent determination of the number of air compressors corresponding to the economizer ash hopper, air preheater ash hopper, and dust collector ash hopper.

[0061] S1023, determine the first target ratio of the first ratio to the sum, determine the second target ratio of the second ratio to the sum, and determine the third target ratio of the third ratio to the sum.

[0062] For the embodiments of this application, taking step S1022 as an example, the electronic device uses 1 / 3 ÷ 13 / 12 = 13 / 36, which is the first target ratio corresponding to the economizer ash hopper. The electronic device uses 1 / 4 ÷ 13 / 12 = 13 / 36, which is the second target ratio corresponding to the air preheater ash hopper. The electronic device uses 1 / 2 ÷ 13 / 12 = 13 / 24, which is the third target ratio corresponding to the dust collector ash hopper.

[0063] S1024, multiply the total number of air compressors by the first target ratio and round down to obtain the number of air compressors in the economizer ash hopper, multiply the total number of air compressors by the second target ratio and round down to obtain the number of air compressors in the air preheater ash hopper, and multiply the total number of air compressors by the third target ratio and round down to obtain the number of air compressors in the dust collector ash hopper.

[0064] For the embodiments of this application, assuming the number of air compressors is 15, taking step S1023 as an example, the electronic device multiplies 15 by 13 / 36 to approximately equal 5.4, and then rounds 5.4 to obtain 5 air compressors for the economizer ash hopper. The electronic device multiplies 15 by 13 / 48 to approximately equal 4.6, and then rounds 4.6 to obtain 4 air compressors for the air preheater ash hopper. The electronic device multiplies 15 by 13 / 24 to approximately equal 8.15, and then rounds 8.15 to obtain 8 air compressors for the air preheater ash hopper. If the total number of required air compressors for each of these components exceeds the total number of air compressors, then the total number of air compressors is subtracted from the required number of air compressors for the two ash hoppers with the highest importance, and the remaining number of air compressors is determined as the number of ash hoppers with the lowest importance.

[0065] One possible implementation of this application embodiment is that step S105 determines the operating state value of each air compressor based on the exhaust pressure change curve and continuous operating time of each air compressor, specifically including steps S1051 (not shown in the figure) and S1052 (not shown in the figure), wherein, S1051, determine the average discharge pressure and discharge pressure variance of each air compressor based on the discharge pressure variation curve of each air compressor.

[0066] In this embodiment, the exhaust pressure change curve is the curve for each air compressor after the current start-up. The electronic device calculates the average exhaust pressure of each air compressor after start-up using an average value calculation formula. The average exhaust pressure represents the overall exhaust pressure level of the air compressor after start-up. A higher average exhaust pressure indicates that the air compressor can output compressed air at a higher pressure level, and the better the working condition of the air compressor. The electronic device calculates the variance of the exhaust pressure of each air compressor after start-up using a variance calculation formula. A larger variance indicates that the exhaust pressure of the air compressor is more unstable and the working condition is worse.

[0067] S1052, determine the product of the exhaust pressure variance and the continuous working time, and determine the ratio of the average exhaust pressure to the product. The ratio represents the working state value of each air compressor.

[0068] In the embodiments of this application, a larger discharge pressure variance indicates a worse working condition, and a longer continuous working time indicates a higher probability of the air compressor experiencing unstable operation, malfunctions, or other abnormalities. Therefore, the electronic equipment multiplies the discharge pressure variance by the continuous working time to obtain a product. A larger product for a given air compressor indicates a worse working condition, while a smaller product indicates a better working condition. Then, the electronic equipment divides the average discharge pressure by the above product to obtain a ratio, which represents the working condition of each air compressor. The average discharge pressure is used as the numerator, and the product as the denominator; therefore, a larger ratio indicates a better working condition for the air compressor. Determining the working condition value by using the above ratio based on the discharge pressure variance, average discharge pressure, and continuous working time is more accurate.

[0069] One possible implementation of this application embodiment involves determining the corresponding target air compressor in step S106 based on the number and importance of the air compressors corresponding to the economizer ash hopper, air preheater ash hopper, and dust collector ash hopper, as well as the operating status value of each air compressor. Specifically, this includes steps S1061 (not shown in the figure), S1062 (not shown in the figure), and S1063 (not shown in the figure). S1061, sort all air compressors from highest to lowest according to their operating status values ​​to obtain the first sorting result.

[0070] In the embodiments of this application, after the electronic device determines the working status value of each air compressor, it sorts all the air compressors in descending order according to the working status value from high to low to obtain the first sorting result.

[0071] S1062, the economizer ash hopper, air preheater ash hopper and dust collector ash hopper are sorted from high to low according to their importance to obtain the second sorting result.

[0072] In the embodiments of this application, after the electronic device determines the importance of the economizer ash hopper, etc., it sorts the economizer ash hopper, air preheater ash hopper and dust collector ash hopper in descending order of importance to obtain a second sorting result.

[0073] S1063, sequentially determine the target air compressor corresponding to each ash hopper from the first sorting result according to the number of corresponding air compressors in the second sorting result.

[0074] In the embodiments of this application, assuming that the second sorting result consists of dust collector hopper, economizer hopper, and air preheater hopper in that order, the target air compressors for the dust collector hopper are selected first. That is, the target air compressors for the dust collector hopper are determined starting from the first position in the first sorting result until the required number of air compressors for the dust collector hopper is reached. Then, the target air compressors for the economizer hopper are selected, starting from the remaining air compressors in the first sorting result until the required number of air compressors for the economizer hopper is reached. Finally, the target air compressors for the air preheater hopper are selected, starting from the last remaining air compressors in the first sorting result. If the number of the last remaining air compressors meets the required number of air compressors for the air preheater hopper, the target air compressors for the air preheater hopper are determined sequentially until the required number of air compressors for the air preheater hopper is reached. If the number of the last remaining air compressors does not meet the required number of air compressors for the air preheater hopper, all the last remaining air compressors are determined as the target air compressors for the air preheater hopper. By ranking the operating status of air compressors and the importance of economizer ash hoppers, the target air compressors for each type of compressor can be more accurately and reasonably determined based on the ranking results, thus meeting their respective needs.

Therefore, the importance determination module 204 can accurately determine the importance of each component based on its ash storage capacity and time interval. The higher the importance, the more air compressors in good working condition are needed for soot blowing. The exhaust pressure change curve and continuous working time are key factors in characterizing the working condition of the air compressor. Therefore, the working condition determination module 205 can accurately determine the working condition value of each air compressor based on its exhaust pressure change curve and continuous working time. Finally, the air compressor allocation module 206 can determine the air compressors that meet the needs and the appropriate number of air compressors based on the required number of air compressors, importance, and working condition of each component, such as the economizer ash hopper.
