[0031] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0032] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0033] In the related art, thermal power generators usually generate electricity at a constant output power to meet the needs of the power load. However, the inventors found that the power load is different in different time periods, with high power loads in some time periods and low power loads in other time periods. When generating electricity at a constant output power under low power load conditions, it will lead to a waste of power generation resources.

[0034] In view of this, the present disclosure provides a control method and corresponding device for a thermal power generating set to solve the technical problems existing in the above-mentioned related technologies.

[0035] like Figure 1 As shown, Figure 1 is a schematic diagram showing a control method for a thermal power generating set according to an exemplary embodiment of the present disclosure, with reference to Figure 1 ,include: S101: determining preset load data, preset electricity price and consumables data generated by the thermal power generating set in a power generation operation process in each of a plurality of time periods, wherein the plurality of time periods are within a time period during which the thermal power generating set is to be operated; S102: for each time period, determining the fuel data of the thermal power generating set according to the preset load data of the time period, and inputting the consumables data, the fuel data and the preset electricity price into a revenue model to obtain the power generation revenue corresponding to the time period; S103: Determine the time period in which the power generation revenue is greater than the preset revenue as the target time period, and control the operation process of the thermal power generating set in the actual time period according to the preset load data corresponding to the target time period, wherein the actual time period is the actual operation time of the thermal power generating set corresponding to the target time period during the waiting operation time.

[0036] Through the above technical scheme, before the operation of the thermal power generating set, the fuel data of the corresponding thermal power generating set is determined according to the preset load data of the thermal power generating set in the time period, and the consumables data, fuel data and preset electricity price of the thermal power generating set in the power generation operation process are input into the profit model to obtain the power generation profit of the corresponding time period. After that, the time period in which the power generation profit is greater than the preset profit is determined as the target time period, and according to the preset load data corresponding to the target time period, the operation process of the thermal power generating set in the actual time period is controlled, wherein the actual time period is the actual operation time of the thermal power generating set corresponding to the target time period during the waiting time. Before the operation of the thermal power generating set, the preset load data of the thermal power generating set in the waiting time can be predicted, and the target time period can be determined according to the preset load data, consumables data and preset electricity price, which can improve the accuracy of the target time period, and then improve the operation efficiency of the thermal power generating set in the actual time period corresponding to the target time period, and at the same time reduce the waste of power generation resources of the thermal power generating set.

[0037] In order to enable those skilled in the art to better understand the control method and corresponding device of the thermal power generating set provided by the present disclosure, the above steps are described in detail with examples below.

[0038] For example, the multiple time periods may be within the time period when the thermal power generating set is to be operated. For example, if the thermal power generating set is to be operated on the second day, the multiple time periods may be within the time period of the second day.

[0039] The preset load data may be the power load data required in multiple time periods predicted based on the power load data of the user in the historical time period. The preset load data may be determined based on the power grid dispatching platform, and the embodiments of the present disclosure do not make specific limitations on this. The preset electricity price may be the electricity price predicted for multiple time periods based on the electricity price used by the user in the historical time period. The consumables data may be the material data required by the power generation equipment during the power generation operation of the thermal power generating set, such as steel ball data, stone powder data, and liquid ammonia data, and the embodiments of the present disclosure do not make specific limitations on this.

[0040] In a possible manner, determining the preset load data of the thermal power generating set in each of the multiple time periods includes: For each time period, respectively obtain preset sub-load data of the thermal power generating set in multiple sub-time periods in the time period, wherein the total duration of the multiple sub-time periods is the same as the duration of the corresponding time period; According to the preset sub-load data of each sub-time period, average preset sub-load data of the multiple sub-time periods is calculated, and the average preset sub-load data is determined as the preset load data.

[0041] It should be understood that when determining the preset load data for each time period, each time period may be divided into multiple sub-time periods, and the preset sub-load data in the multiple sub-time periods may be obtained respectively. Then, the average preset sub-load data of the preset sub-load data in the multiple sub-time periods may be calculated, and the average preset sub-load data may be used as the preset load data.

[0042] When determining the load data corresponding to each time period, the accuracy of the preset load data can be improved by calculating the average preset sub-load data among the preset sub-load data in multiple sub-time periods, thereby improving the accuracy of the target time period.

[0043] In a possible way, the consumable data of the thermal power generating unit in each time period during the power generation operation is determined, including: Determine the unit consumption data of steel balls, the unit consumption data of stone powder and the unit consumption data of liquid ammonia required by the thermal power generating set during power generation operation in each time period; The consumables data for each time period is determined by the unit consumption data of the steel balls, the unit consumption data of the stone powder and the unit consumption data of the liquid ammonia.

[0044] It should be understood that when determining the consumables data, the steel ball consumption data, stone powder consumption data, and liquid ammonia consumption data required by the thermal power generating set during the power generation operation in each time period can be determined, and then the steel ball consumption data, stone powder consumption data, and liquid ammonia consumption data can be added to obtain the consumables data for each time period. This is not specifically limited in the embodiments of the present disclosure.

[0045] For example, the fuel data may be the data of the fuel used by the thermal power generating set during the fuel combustion and power generation process. The fuel data may be determined according to the preset load data, and then the corresponding power generation income of the thermal power generating set in the time period is determined according to the fuel data, the consumables data and the preset electricity price.

[0046] The revenue model may be a model for calculating the revenue of a thermal power generating unit during operation. The revenue model may be determined based on fuel data, consumables data, and a preset electricity price, thereby improving the accuracy of power generation revenue, and the accuracy of external quotations may be improved based on the power generation revenue.

[0047] In a possible manner, determining the fuel data of the thermal power generating set according to the preset load data of the time period includes: Calculating the coal consumption data, furnace coal calorific value parameters, sulfur content parameters and volatile content parameters of the thermal power generating set according to the preset load data; Determine the target standard coal unit price of the thermal power generating set according to the correlation relationship between the furnace coal calorific value parameter, the sulfur content parameter, the volatile matter parameter and the standard coal unit price, wherein the standard coal unit price correlation relationship is used to characterize the relationship between the furnace coal calorific value parameter, the sulfur content parameter, the volatile matter parameter and the standard coal unit price; The fuel data of the thermal power generating set is determined according to the target standard coal unit price and the coal consumption data.

[0048] It should be understood that when determining the fuel data within a time period, the coal consumption data, furnace coal calorific value parameters, sulfur parameters and volatile matter parameters of the thermal power generating set can be calculated based on the preset load data. Among them, the coal consumption data of the thermal power generating set can be the average amount of standard coal consumed by the thermal power generating set per kilowatt-hour of electricity supplied. The furnace coal calorific value parameters can include the calorific value of the incoming coal and the calorific value of the incoming coal, wherein the calorific value of the incoming coal can be the weighted average value of the low calorific value of the incoming coal of the thermal power generating set during the operation statistical period, and the calorific value of the incoming coal can be the weighted average value of the low calorific value of the incoming coal of the thermal power generating set during the operation statistical period. The sulfur content parameter can be an important impurity in the coal. The volatile matter parameter can be the mass loss of the coal after moisture correction by isolating it from air under specified conditions.

[0049] The standard coal unit price correlation relationship can be the relationship between the furnace coal calorific value parameter, sulfur parameter, volatile matter parameter and the standard coal unit price. Different furnace coal calorific value parameters, sulfur parameters and volatile matter parameters can correspond to different standard coal unit prices. For example, when the furnace coal calorific value parameter is 4200, the sulfur parameter is 0.6 and the volatile matter parameter is 11, the standard coal unit price can be 920.1; when the furnace coal calorific value parameter is 4500, the sulfur parameter is 0.3 and the volatile matter parameter is 11, the standard coal unit price can be 913.24. In this embodiment, the target standard coal unit price can be determined based on the correlation relationship between the furnace coal calorific value parameter, sulfur parameter and volatile matter parameter and the standard coal unit price. Then, the fuel data of the thermal power generator set is determined based on the target standard coal unit price and the coal consumption data.

[0050] like Figure 2 As shown, in Figure 2 In the figure, the horizontal axis can be the preset load data, and the vertical axis can be the coal consumption data. The solid line can represent the coal consumption trend curve obtained during the test of the thermal power generating unit, and the dotted line can be obtained after fitting the coal consumption trend curve. Therefore, the coal consumption data can be calculated by the following calculation formula.

[0051]

[0052] Among them, A is the coal consumption data, and B is the preset load data.

[0053] When determining the fuel data of a thermal power generating unit according to the target standard coal price and the coal consumption data, the target standard coal price and the fuel data can be multiplied to obtain the fuel data. The accuracy of the fuel data can be improved by calculating the coal consumption data and the target standard coal price according to the preset load data and then multiplying the coal consumption data and the target standard coal price.

[0054] For example, the preset benefit may be a critical benefit of whether the thermal power generating set generates benefit or not during operation, and the embodiments of the present disclosure do not specifically limit this. When the power generation benefit is greater than the preset benefit, it may represent that the thermal power generating set generates benefit at this time, and then the time period corresponding to the power generation benefit may be determined as the target time period. Thereafter, during the actual operation of the thermal power generating set, the operation process of the thermal power generating set in the actual time period may be controlled according to the preset load data corresponding to the target time period, wherein the actual time period is the actual operation time of the thermal power generating set corresponding to the target time period during the waiting time.

[0055] By controlling the power generation operation process of the thermal power generating unit in the actual time period through the preset load data corresponding to the target time period, the power generation efficiency of the thermal power generating unit can be improved, and at the same time, the utilization efficiency of the power generated by the thermal power generating unit can be improved, thereby reducing the waste of power generation resources.

[0056] In a possible manner, the controlling the operation process of the thermal power generating set in the actual time period according to the preset load data corresponding to the target time period includes: Acquire target load data for controlling the operation process of the thermal power generating set, wherein the load rate corresponding to the target load data is greater than or equal to the load rate corresponding to the preset load data within the target time period; According to the target load data, the operation process of the thermal power generating set in the actual time period is controlled.

[0057] It should be understood that the actual time period may be a time period corresponding to the target time period, and the target time period may be a time period in which the power load demand is predicted to be relatively high. Thus, when the thermal power generating set is operated in the actual time period, the operation process of the thermal power generating set may be controlled by the preset load data corresponding to the target time period that is greater than or equal to that of the target time period. Thus, the load data generated by the thermal power generating set during the operation process in the actual time period may be increased to meet the power load. At the same time, relevant personnel may make external quotations based on the extra load data, thereby increasing the power generation revenue of the thermal power generating set.

[0058] By controlling the operation process of the thermal power generating set by the preset load data corresponding to the target time period being greater than or equal to the target time period, the operation efficiency of the thermal power generating set can be improved when the power load is high, and then the operation efficiency of the thermal power generating set can be reduced when the power load is low, thereby reducing the waste of the generating point resources of the thermal power generating set.

[0059] In a possible manner, the controlling the operation process of the thermal power generating set in the actual time period according to the preset load data corresponding to the target time period includes: Determining a target furnace coal calorific value parameter, a target sulfur parameter, and a target volatile matter parameter of the thermal power generating set according to the preset load data corresponding to the target time period; The operation process of the thermal power generator in the actual time period is controlled according to the target furnace coal calorific value parameter, the target sulfur parameter and the target volatile matter parameter.

[0060] It should be understood that when controlling the operation of the thermal power generating set in the actual time period, control can also be performed according to the furnace coal calorific value parameter, the sulfur content parameter, and the volatile content parameter. The target furnace coal calorific value parameter, the target sulfur content parameter, and the target volatile content parameter of the thermal power generating set can be determined according to the preset load data corresponding to the target time period. After that, during the operation of the thermal power generating set in the actual time period, the operation of the thermal power generating set can be controlled by the target furnace coal calorific value parameter, the target sulfur content parameter, and the target volatile content parameter, thereby increasing the load of the thermal power generating set in the actual time period and reducing the waste of power generation resources of the thermal power generating set.
