Description

Technical Field

[0001] This disclosure relates to the field of thermal power generation technology, and more specifically, to a coal feeding control method, apparatus, storage medium, and electronic equipment. Background Technology

[0002] A thermal power plant, or coal-fired power plant for short, typically uses coal as fuel to produce electricity. Its basic process is as follows: a coal feeder transports coal to a coal bunker, which then supplies coal via a coal feeder. As the coal burns, it heats water to generate steam, converting the chemical energy of the coal into heat energy. The steam pressure drives a turbine to rotate, converting the heat energy into mechanical energy. The turbine then drives a generator to rotate, converting the mechanical energy into electrical energy.

[0003] In related technologies, in order to ensure sufficient power generation, high-calorific-value coal is used for power generation. However, since high-calorific-value coal is expensive, the total cost of thermal power generation also increases. Summary of the Invention

[0004] The purpose of this disclosure is to provide a coal feeding control method, apparatus, storage medium, and electronic device to solve problems in related technologies.

[0005] To achieve the above objectives, according to a first aspect of the present disclosure, a coal feeding control method is provided, the method comprising:

[0006] Obtain historical electricity demand information, which includes multiple adjacent historical electricity consumption time intervals and the electricity demand corresponding to each historical electricity consumption time interval;

[0007] Based on the multiple adjacent historical electricity consumption time intervals and the electricity demand corresponding to each historical electricity consumption time interval, the first switching time point and the second switching time point are determined.

[0008] Based on the first switching time point, the coal feeder is controlled to replenish the raw coal bunker with first calorific value coal so that when the electricity demand exceeds the electricity threshold, the raw coal bunker supplies the first calorific value coal to the coal feeder for power generation.

[0009] According to the second switching time point, the coal feeder is controlled to replenish the raw coal bunker with second calorific value coal, so that when the electricity demand is less than or equal to the electricity threshold, the raw coal bunker supplies the coal feeder with the second calorific value coal to generate electricity, wherein the calorific value of the first calorific value coal is greater than the calorific value of the second calorific value coal.

[0010] Optionally, there is a common time point between every two adjacent historical electricity consumption time intervals. The step of determining the first switching time point and the second switching time point based on the plurality of adjacent historical electricity consumption time intervals and the electricity demand corresponding to each historical electricity consumption time interval includes:

[0011] The electricity demand corresponding to each historical electricity consumption time interval is compared with the electricity consumption threshold, and the electricity demand that is greater than the electricity consumption threshold is determined as the first demand, and the electricity demand that is less than or equal to the electricity consumption threshold is determined as the second demand.

[0012] When the electricity demand corresponding to two adjacent historical electricity consumption time intervals is the second demand and the first demand in chronological order, the common time point in the two adjacent historical electricity consumption time intervals is determined as the first switching time point.

[0013] When the electricity demand corresponding to two adjacent historical electricity consumption time intervals is ranked according to the first demand and the second demand in chronological order, the common time point in the two adjacent historical electricity consumption time intervals is determined as the second switching time point.

[0014] Optionally, the step of controlling the coal feeder to replenish the raw coal bunker with coal of the first calorific value according to the first switching time point includes:

[0017] Before the second switching time point, the coal feeder is controlled to replenish the raw coal bunker with coal of the second calorific value.

[0018] Optionally, the method further includes:

[0019] Determine the first total electricity demand between the first switching time point and the second switching time point;

[0020] Based on the calorific value parameters of the first calorific value coal and the first total electricity demand, a first quality value is obtained;

[0021] The control of the coal feeder to replenish the raw coal bunker with first-value coal includes:

[0022] The coal feeder is controlled to replenish the raw coal bunker with coal of a first mass value and a first calorific value.

[0023] Optionally, the method further includes:

[0024] Determine the second total electricity demand between the second switching time point and the first switching time point;

[0025] The second quality value is obtained based on the calorific value parameters of the second calorific value coal and the second total electricity demand.

[0026] Controlling the coal feeder to replenish the raw coal bunker with coal of the second calorific value includes:

[0027] The coal feeder is controlled to replenish the raw coal bunker with coal of a second mass value and a second calorific value.

[0028] Optionally, the method further includes:

[0029] The first coal loading time is obtained based on the first mass value and the coal loading speed of the coal feeder;

[0030] The control of the coal feeder to replenish the raw coal bunker with coal of a first mass value and a first calorific value includes:

[0031] The coal feeder is controlled to replenish the raw coal bunker with coal of the first calorific value for the first loading time according to the coal loading speed;

[0032] The second coal loading time is obtained based on the second mass value and the coal loading speed of the coal feeder;

[0033] The control of the coal feeder to replenish the raw coal bunker with coal of a second mass value and second calorific value includes:

[0034] The coal feeder is controlled to replenish the raw coal bunker with second-value coal for a second loading time according to the coal loading speed.

[0035] According to a second aspect of the present disclosure, a coal feeding control device is provided, the coal feeding control device comprising:

[0036] The first acquisition module is used to acquire historical electricity demand information, which includes multiple adjacent historical electricity consumption time intervals and the electricity demand corresponding to each historical electricity consumption time interval.

[0037] The first determining module is used to determine the first switching time point and the second switching time point based on the plurality of adjacent historical electricity consumption time intervals and the electricity demand corresponding to each of the historical electricity consumption time intervals.

[0038] The first coal feeding module is used to control the coal feeder to replenish the raw coal bunker with the first calorific value coal according to the first switching time point, so that when the power demand is greater than the power demand threshold, the raw coal bunker supplies the first calorific value coal to the coal feeder for power generation.

[0039] The second coal feeding module is used to control the coal feeder to replenish the raw coal bunker with second calorific value coal according to the second switching time point, so that when the electricity demand is less than or equal to the electricity threshold, the raw coal bunker supplies the coal feeder with the second calorific value coal to generate electricity, wherein the calorific value of the first calorific value coal is greater than the calorific value of the second calorific value coal.

[0040] According to a third aspect of the present disclosure, a non-transitory computer-readable storage medium is provided, on which a computer program is stored, which, when executed by a processor, implements the steps of any of the coal feeding control methods provided in the first aspect of the present disclosure.

[0041] According to a fourth aspect of the present disclosure, an electronic device is provided, comprising:

[0042] A memory on which computer programs are stored;

[0043] A processor is configured to execute the computer program in the memory to implement the steps of any of the coal feeding control methods provided in the first aspect of this disclosure.

[0044] Using the above technical solution, historical electricity demand information is obtained, including multiple adjacent historical electricity consumption time intervals and the corresponding electricity demand for each historical electricity consumption time interval. Then, based on these multiple adjacent historical electricity consumption time intervals and the corresponding electricity demand for each historical electricity consumption time interval, a first switching time point and a second switching time point are determined. According to the first switching time point, the coal feeder is controlled to replenish the raw coal bunker with first-value coal, so that when the electricity demand exceeds the electricity threshold, the raw coal bunker supplies the first-value coal to the coal feeder for power generation. According to the second switching time point, the coal feeder is controlled to replenish the raw coal bunker with second-value coal, so that when the electricity demand is less than or equal to the electricity threshold, the raw coal bunker supplies the second-value coal to the coal feeder for power generation. The calorific value of the first-value coal is greater than that of the second-value coal. By controlling the coal feeder to feed coal into the raw coal bunker according to the first switching time point, when the electricity demand is greater than the electricity threshold, the raw coal bunker supplies the coal feeder with coal of the first calorific value with a high calorific value for power generation. According to the second switching time point, the coal feeder is controlled to feed coal into the raw coal bunker, so that when the electricity demand is less than or equal to the electricity threshold, the raw coal bunker supplies the coal feeder with coal of the second calorific value with a low calorific value for power generation. By supplying coal of different calorific values ​​for power generation according to different electricity demands, the power supply is guaranteed while saving the cost of thermal power generation.

[0045] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0055] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0056] In the following description, the words "first" and "second" are used only to distinguish the purpose of the description and should not be interpreted as indicating or implying relative importance or order.

[0057] A thermal power plant, also known as a coal-fired power plant, typically uses coal as fuel to produce electricity. Please refer to [link / reference]. Figure 1 The basic process is as follows: the coal feeder 11 transports the coal to the raw coal bunker 12, the raw coal bunker 12 supplies the coal through the coal feeder 13, the coal heats water to generate steam when it is burning, converting the chemical energy of the coal into heat energy, the steam pressure drives the turbine to rotate, the heat energy is converted into mechanical energy, and then the turbine drives the generator to rotate, converting the mechanical energy into electrical energy.

[0058] In the process of generating electricity in thermal power plants, high-calorific-value coal is used to ensure sufficient power generation. However, since high-calorific-value coal is expensive, the total cost of thermal power generation also increases.

[0059] To address the aforementioned issues, this disclosure provides a coal feeding control method. Based on a first switching time point, the coal feeder 11 feeds coal to the raw coal bunker 12. When the electricity demand exceeds the electricity threshold, the raw coal bunker 12 supplies the coal feeder 13 with high-calorific-value coal for power generation. Based on a second switching time point, the coal feeder 11 feeds coal to the raw coal bunker 12. When the electricity demand is less than or equal to the electricity threshold, the raw coal bunker 12 supplies the coal feeder 13 with low-calorific-value coal for power generation. By supplying coal of different calorific values ​​according to different electricity demands, power generation is achieved while ensuring electricity supply and saving on thermal power generation costs.

[0060] Figure 1 This is a flowchart illustrating a coal feeding control method according to an exemplary embodiment. The coal feeding control method can be applied to electronic devices, such as… Figure 1 As shown, a coal feeding control method may include steps S1 to S3:

[0061] Step S1: Obtain historical electricity demand information, which includes multiple adjacent historical electricity consumption time intervals and the electricity demand corresponding to each historical electricity consumption time interval.

[0062] Historical electricity demand information can be any information from previous days. For example, it could refer to the electricity demand information of the previous day, the average daily electricity demand information of the previous month, or the average daily electricity demand information of the previous quarter.

[0063] Divide a day into N equal parts, each of which represents a historical electricity consumption time interval. For example, if a day is divided into 24 equal parts, each historical electricity consumption time interval is one hour in size; if a day is divided into 12 equal parts, each historical electricity consumption time interval is two hours in size. Since each historical electricity consumption time interval is one hour in size, the historical electricity consumption time intervals could be [0, 1], [1, 2], [2, 3], ..., [10, 11], [11, 12], ..., [22, 23], [23, 0]. Here, [0, 1] and [1, 2] are adjacent historical electricity consumption time intervals, [1, 2] and [2, 3] are adjacent historical electricity consumption time intervals, [10, 11] and [11, 12] are adjacent historical electricity consumption time intervals, and [22, 23] and [23, 0] are adjacent historical electricity consumption time intervals. In other embodiments, the day can be divided in a non-uniform manner to obtain multiple historical electricity consumption time intervals, which are not limited here.

[0064] The electricity demand corresponding to the historical electricity consumption time interval can be the amount of electricity needed within that historical electricity consumption time interval.

[0065] Step S2: Based on multiple adjacent historical electricity consumption time intervals and the electricity demand corresponding to each historical electricity consumption time interval, determine the first switching time point and the second switching time point.

[0066] Electricity demand is compared to a threshold. When the demand exceeds the threshold, it is considered high demand; when the demand is below the threshold, it is considered low demand. The first switching time characterizes the transition from low to high demand, and the second switching time characterizes the transition from high to low demand.

[0067] Step S3: According to the first switching time point, control the coal feeder 11 to replenish the first calorific value coal to the raw coal bunker 12 so that when the electricity demand is greater than the electricity threshold, the raw coal bunker 12 supplies the first calorific value coal to the coal feeder 13 for power generation.

[0068] Based on the first switching time point, the coal feeder 11 is controlled to replenish the raw coal bunker 12 with coal of the first calorific value. This can be understood as, based on the first switching time point, the coal feeder 11 is controlled to replenish the raw coal bunker 12 with coal of the first calorific value in advance, so that at the first switching time point, that is, when the electricity demand is greater than the electricity threshold, the raw coal bunker 12 can supply the coal feeder 13 with coal of the first calorific value with a high calorific value to generate electricity, so as to meet the high electricity demand.

[0069] Step S4: According to the second switching time point, control the coal feeder 11 to supplement the raw coal bunker 12 with second calorific value coal so that when the electricity demand is less than or equal to the electricity threshold, the raw coal bunker 12 supplies the coal feeder 13 with second calorific value coal for power generation, wherein the calorific value of the first calorific value coal is greater than that of the second calorific value coal.

[0070] According to the second switching time point, the coal feeder 11 is controlled to supplement the raw coal bunker 12 with coal of the second calorific value. This can be understood as, according to the second switching time point, the coal feeder 11 is controlled to supplement the raw coal bunker 12 with coal of the second calorific value in advance, so that when the electricity demand is less than or equal to the electricity demand threshold at the second switching time point, the raw coal bunker 12 can supply the coal feeder 13 with coal of the second calorific value with a low calorific value to generate electricity, so as to meet the low electricity demand.

[0071] By controlling the coal feeder 11 to feed coal to the raw coal bunker 12 according to the first switching time point, when the electricity demand is greater than the electricity threshold, the raw coal bunker 12 supplies the coal feeder 13 with coal of higher calorific value for power generation. According to the second switching time point, the coal feeder 11 is controlled to feed coal to the raw coal bunker 12, so that when the electricity demand is less than or equal to the electricity threshold, the raw coal bunker 12 supplies the coal feeder 13 with coal of lower calorific value for power generation. By supplying coal of different calorific values ​​for power generation according to different electricity demands, the power supply is guaranteed while the cost of thermal power generation is saved.

[0072] In one possible implementation, there is a common point in time between every two adjacent historical electricity consumption intervals; see [link to relevant documentation]. Figure 3 Step S2 may include steps S21 to S23:

[0073] Step S21: Compare the electricity demand corresponding to each historical electricity consumption time interval with the electricity consumption threshold, and determine the electricity demand that is greater than the electricity consumption threshold as the first demand, and determine the electricity demand that is less than or equal to the electricity consumption threshold as the second demand.

[0074] Step S22: When the electricity demand corresponding to two adjacent historical electricity consumption time intervals is the second demand and the first demand in chronological order, the common time point in the two adjacent historical electricity consumption time intervals is determined as the first switching time point.

[0075] Step S23: When the electricity demand corresponding to two adjacent historical electricity consumption time intervals is ranked as the first demand and the second demand in chronological order, the common time point in the two adjacent historical electricity consumption time intervals is determined as the second switching time point.

[0076] The first demand can be a high demand for electricity, and the second demand can be a low demand for electricity. The level of demand for electricity can be determined by comparing it with the electricity demand threshold, which can be set by the user according to the actual situation.

[0077] There is a common time point between every two adjacent historical electricity consumption time intervals. For example, points [0, 1] and [1, 2] are adjacent historical electricity consumption time intervals, and their common time point is 1; points [1, 2] and [2, 3] are adjacent historical electricity consumption time intervals, and their common time point is 2; points [10, 11] and [11, 12] are adjacent historical electricity consumption time intervals, and their common time point is 11; points [22, 23] and [23, 0] are adjacent historical electricity consumption time intervals, and their common time point is 23.

[0078] When the electricity demand corresponding to two adjacent historical electricity consumption time intervals is the second demand and the first demand in chronological order, that is, when the electricity demand changes from low to high, the common time point in the two adjacent historical electricity consumption time intervals is determined as the first switching time point.

[0079] When the electricity demand corresponding to two adjacent historical electricity consumption time intervals is the first demand and the second demand in chronological order, that is, when the electricity demand changes from high to low, the common time point in the two adjacent historical electricity consumption time intervals is determined as the second switching time point.

[0080] In one possible implementation, based on a first switching time point, controlling the coal feeder 11 to replenish the raw coal bunker 12 with coal of a first calorific value includes:

[0081] Before the first switching time point, control the coal feeder 11 to replenish the raw coal bunker 12 with first-calorific-value coal.

[0082] Before the first switching time point, the coal feeder 11 is controlled to replenish the raw coal bunker 12 with first calorific value coal to ensure that at the first switching time point, the raw coal bunker 12 has first calorific value coal to supply the coal feeder 13 for power generation.

[0083] In one possible implementation, based on a second switching time point, the coal feeder 11 is controlled to replenish the raw coal bunker 12 with coal of a second calorific value, including:

[0084] Before the second switching time point, control the coal feeder 11 to replenish the raw coal bunker 12 with second calorific value coal.

[0085] Before the second switching time point, the coal feeder 11 is controlled to replenish the raw coal bunker 12 with second calorific value coal to ensure that at the second switching time point, the raw coal bunker 12 has second calorific value coal to supply the coal feeder 13 for power generation.

[0086] In one possible implementation, please refer to Figure 4 , Figure 4 This is a flowchart illustrating another coal feeding control method according to an exemplary embodiment, which may include steps S301 to S306:

[0087] Step S301: Obtain historical electricity demand information, which includes multiple adjacent historical electricity consumption time intervals and the electricity demand corresponding to each historical electricity consumption time interval.

[0088] Step S302: Based on multiple adjacent historical electricity consumption time intervals and the electricity demand corresponding to each historical electricity consumption time interval, determine the first switching time point and the second switching time point.

[0089] Step S303: Determine the first total power demand between the first switching time point and the second switching time point.

[0090] The electricity demand corresponding to all historical electricity consumption time intervals between the first switching time point and the second switching time point is accumulated to obtain the first total electricity demand.

[0091] For example, if the first switching time is 7 o'clock and the second switching time is 10 o'clock, then the electricity demand corresponding to all historical electricity consumption time intervals between the first and second switching time points, namely [7, 8] o'clock, [8, 9] o'clock, and [9, 10] o'clock, needs to be accumulated to obtain the first total electricity consumption.

[0092] Step S304: Obtain the first quality value based on the calorific value parameters of the first calorific value coal and the first total electricity demand.

[0093] Based on the conversion relationship between electricity and coal energy, first calculate the coal energy value required for the first total electricity demand, and then, based on the coal energy value and calorific value parameters, obtain the mass of coal with the first calorific value required, i.e., the first mass value.

[0094] Step S305: According to the first switching time point, control the coal feeder 11 to replenish the raw coal bunker 12 with the first calorific value coal of the first quality value, so that when the power demand is greater than the power demand threshold, the raw coal bunker 12 supplies the coal feeder 13 with the first calorific value coal for power generation.

[0095] Before the first switching time point, the coal feeder 11 is controlled to replenish the raw coal bunker 12 with the first quality value of the first calorific value coal, so that at the first switching time point, that is, when the power demand is greater than the power demand threshold, the raw coal bunker 12 can supply the coal feeder 13 with the first quality value of the first calorific value coal to generate electricity, so as to meet the high power demand.

[0096] Step S306: According to the second switching time point, control the coal feeder 11 to supplement the raw coal bunker 12 with second calorific value coal so that when the electricity demand is less than or equal to the electricity threshold, the raw coal bunker 12 supplies the coal feeder 13 with second calorific value coal for power generation, wherein the calorific value of the first calorific value coal is greater than the calorific value of the second calorific value coal.

[0097] It should be noted that the detailed descriptions of steps S301, S302 and S306 can be found in steps S1, S2 and S4 respectively, and will not be repeated here in this embodiment.

[0098] By calculating the first mass value between the first switching time point and the second switching time point, and then controlling the coal feeder 11 to replenish the raw coal bunker 12 with the first calorific value coal of the first mass value, the coal is added precisely, which saves the cost of thermal power generation while ensuring the power supply.

[0099] In one possible implementation, please refer to Figure 5 , Figure 5 This is a flowchart illustrating another coal feeding control method according to an exemplary embodiment, which may include steps S401 to S408:

[0100] Step S401: Obtain historical electricity demand information, which includes multiple adjacent historical electricity consumption time intervals and the electricity demand corresponding to each historical electricity consumption time interval.

[0101] Step S402: Based on multiple adjacent historical electricity consumption time intervals and the electricity demand corresponding to each historical electricity consumption time interval, determine the first switching time point and the second switching time point.

[0102] Step S403: Determine the first total power demand between the first switching time point and the second switching time point.

[0103] Step S404: Obtain the first quality value based on the calorific value parameters of the first calorific value coal and the first total electricity demand.

[0104] In step S405, according to the first switching time point, the coal feeder 11 is controlled to replenish the raw coal bunker 12 with the first calorific value coal of the first quality value, so that when the electricity demand is greater than the electricity threshold, the raw coal bunker 12 supplies the coal feeder 13 with the first calorific value coal for power generation.

[0105] Step S406: Determine the second total power demand between the second switching time point and the first switching time point.

[0106] The electricity demand corresponding to all historical electricity consumption time intervals between the second switching time point and the first switching time point is summed to obtain the second total electricity demand.

[0107] For example, if the second switching time point is 10:00 and the second switching time point is 14:00, then the electricity demand corresponding to all historical electricity consumption time intervals between the first switching time point and the second switching time point, namely [10, 11], [11, 12], [12, 13], and [13, 14], needs to be accumulated to obtain the second total electricity consumption.

[0108] Step S407: Obtain the second quality value based on the calorific value parameters of the second calorific value coal and the second total electricity demand.

[0109] Based on the conversion relationship between electricity and coal energy, first calculate the coal energy value required for the second total electricity demand, and then obtain the required mass of coal with the second calorific value, i.e., the second mass value, based on the coal energy value and calorific value parameters.

[0110] Step S408: According to the second switching time point, control the coal feeder 11 to supplement the raw coal bunker 12 with the second calorific value coal of the second quality value, so that when the electricity demand is less than or equal to the electricity threshold, the raw coal bunker 12 supplies the coal feeder 13 with the second calorific value coal for power generation, wherein the calorific value of the first calorific value coal is greater than the calorific value of the second calorific value coal.

[0111] Before the second switching time point, the coal feeder 11 is controlled to replenish the raw coal bunker 12 with the second calorific value coal of the second quality value, so that at the second switching time point, that is, when the power demand is less than or equal to the power demand threshold, the raw coal bunker 12 can supply the coal feeder 13 with the second calorific value coal of the second quality value to generate electricity, so as to meet the low power demand.

[0112] It should be noted that the detailed descriptions of steps S401, S402, S403, S404 and S405 can be found in steps S1, S2, S303, S304 and S305 respectively, and will not be repeated here in this embodiment.

[0113] By calculating the first mass value between the first switching time point and the second switching time point, and then controlling the coal feeder 11 to replenish the raw coal bunker 12 with the first calorific value of the first mass value, and by calculating the second mass value between the second switching time point and the first switching time point, and then controlling the coal feeder 11 to replenish the raw coal bunker 12 with the second calorific value of the second mass value, coal is added precisely, which ensures power supply while saving thermal power generation costs.

[0114] In one possible implementation, please refer to Figure 6 , Figure 6 This is a flowchart illustrating another coal feeding control method according to an exemplary embodiment, which may include steps S501 to S510:

[0115] Step S501: Obtain historical electricity demand information, which includes multiple adjacent historical electricity consumption time intervals and the electricity demand corresponding to each historical electricity consumption time interval.

[0116] Step S502: Based on multiple adjacent historical electricity consumption time intervals and the electricity demand corresponding to each historical electricity consumption time interval, determine the first switching time point and the second switching time point.

[0117] Step S503: Determine the first total power demand between the first switching time point and the second switching time point.

[0118] Step S504: Obtain the first quality value based on the calorific value parameters of the first calorific value coal and the first total electricity demand.

[0119] Step S505: Based on the first mass value and the coal loading speed of the coal feeder 11, the first coal loading time is obtained.

[0120] Step S506: According to the first switching time point, control the coal feeder 11 to replenish the raw coal bunker 12 with first calorific value coal for the first coal loading time according to the coal loading speed, so that when the electricity demand is greater than the electricity threshold, the raw coal bunker 12 supplies the coal feeder 13 with first calorific value coal for power generation.

[0121] Step S507: Determine the second total power demand between the second switching time point and the first switching time point.

[0122] Step S508: Obtain the second quality value based on the calorific value parameters of the second calorific value coal and the second total electricity demand.

[0123] Step S509: Based on the second mass value and the coal loading speed of the coal feeder 11, the second coal loading time is obtained.

[0124] Step S510: According to the second switching time point, control the coal feeder 11 to replenish the raw coal bunker 12 with the second calorific value coal for the second coal loading time according to the coal loading speed, so that when the electricity demand is less than or equal to the electricity threshold, the raw coal bunker 12 supplies the coal feeder 13 with the second calorific value coal for power generation, wherein the calorific value of the first calorific value coal is greater than the calorific value of the second calorific value coal.
