[0049] The specific embodiments of the present invention 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 the scope of the present invention.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this application.

[0051] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0052] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating the method for calculating coal consumption for power supply provided in an embodiment of the present invention. The method includes the following steps:

[0053] S100, real-time acquisition of the load rate of the heating unit; wherein, the load rate is obtained by converting the real-time load of the heating unit;

[0054] Specifically, during actual operation of the unit, the load rate is obtained by converting the load of the heating unit collected in real time by the monitoring system, which is the ratio of the operating load of the heating unit to the maximum operating load, for example: 60.87%.

[0055] S200, based on the load factor, the preset power supply coal consumption benchmark value and the preset load-power supply coal consumption change rate curve, obtains the initial value of power supply coal consumption;

[0056] It should be noted that during actual operation, load rate and ambient temperature will affect the unit's real-time coal consumption for power supply, while the unit's coal consumption for heating will decrease as the load rate increases. The coal consumption for power supply corresponding to 100% load operation is used as the baseline coal consumption. The increase in real-time coal consumption for power supply at other load rates based on the baseline coal consumption is called the coal consumption change rate. Based on long-term operational measurements, the coal consumption change rate corresponding to different load rates is obtained, and this is fitted to form a preset load-coal consumption change rate curve.

[0057] It should be noted that, considering the impact of unit coal consumption for power supply under different temperature conditions, the preset coal consumption benchmark value for power supply is calculated by using the load rate and preset load rate-coal consumption variation curve of the unit operating day during the same period.

[0058] Specifically, the load rate of the heating unit acquired in real time is input into the preset load-power coal consumption change rate curve to obtain the change rate of the benchmark coal consumption under the load rate. Then, combined with the benchmark coal consumption of the heating unit, the initial value of power coal consumption is calculated.

[0059] S300, based on the heat-to-power ratio of the heating unit and the adjustment coefficient of the standard coal consumption for power supply of the heating unit, yields the corrected value of coal consumption for power supply;

[0060] The heat-to-power ratio refers to the ratio of heat supplied by a thermal power plant to electricity supplied (converted to heat). In other words, it's the ratio of the effective utilization of heat to the amount of electricity supplied (converted to heat), for example, 14.6%.

[0061] The standard coal consumption adjustment coefficient for power supply refers to the loss rate of the original coal consumption for power supply in a thermal power plant, for example: 1.5.

[0062] It should be noted that under heating conditions, the real-time coal consumption of the heating unit will be lower than that of the pure condensing unit under the same operating conditions. Therefore, the correction value of the power supply coal consumption of the heating unit is calculated by using the heat-to-power ratio and the power supply standard coal consumption adjustment coefficient, so as to correct the initial value of the power supply coal consumption.

[0063] S400, based on the initial value of coal consumption for power supply and the correction value of coal consumption for power supply, obtains the actual value of coal consumption for power supply.

[0064] Specifically, after calculating the correction value for coal consumption for power supply, the initial value of coal consumption for power supply can be corrected using the correction value to obtain the actual value of coal consumption for power supply.

[0065] In this implementation, the initial value of power supply coal consumption is calculated by acquiring the load rate of the heating unit in real time, the preset load-power coal consumption change rate curve, and the preset power supply coal consumption benchmark value. Then, the initial value of power supply coal consumption is corrected using the heat-to-power ratio of the heating unit and the power supply standard coal consumption adjustment coefficient to obtain the actual value of power supply coal consumption. Because the initial value of power supply coal consumption is corrected by calculating the heat-to-power ratio of the heating unit and the power supply standard coal consumption adjustment coefficient, the final calculated power supply coal consumption is accurate.

[0066] Optionally, the preset load-power coal consumption change rate curve is obtained in the following way:

[0067] Step 1: Obtain the historical load rate of the heating unit and the corresponding rate of change in coal consumption for power supply;

[0068] Step 2: Using formula (1), calculate the historical load factor and the change rate of coal consumption for power supply corresponding to the historical load factor, and fit the load factor-coal consumption change rate curve.

[0069] f(x) = -0.916x 3 +2.491x 2 -2.1882x+0.6585(1);

[0070] Where x represents the historical load factor, and f(x) represents the rate of change in coal consumption for power supply corresponding to the historical load factor.

[0071] To make it easier to understand, the following examples are provided:

[0072] Based on long-term operational measurements, the coal consumption variation rate corresponding to different load rates is shown in the table below:

[0073] Serial Number Load factor Coal consumption change rate 1 30％ 20％ 2 40％ 12％ 3 50％ 7％ 4 60％ 3％ 5 70％ 2％ 6 80％ 1％ 7 100％ 0

[0074] The least squares method was used to fit the data in the table to form a preset load rate-coal consumption change rate curve. The expression of the fitted curve is formula (1): f(x)=-0.916x 3 +2.491x 2 -2.1882x+0.6585.

[0075] After fitting the data in the table above, a two-dimensional coordinate system is constructed with load rate on the horizontal axis and coal consumption change rate on the vertical axis, thereby obtaining the preset load rate-coal consumption change rate curve. This allows the coal consumption change rate corresponding to the load rate of the heating unit at any time to be calculated based on the preset load rate-coal consumption change rate curve.

[0076] In this implementation, by using formula (1), different load rates and corresponding load rates under long-term operation and measurement are fitted to obtain a preset load rate-coal consumption change rate curve that can reflect the law between load rate and coal consumption change rate. Thus, in actual application, the load rate of the heating unit at any time can be calculated based on the preset load rate-coal consumption change rate curve to obtain the corresponding coal consumption change rate.

[0077] Optionally, the baseline value for coal consumption for power generation is obtained in the following way:

[0078] Step 1: Obtain the preset load rate and corresponding coal consumption for power supply of the heating unit;

[0079] Step 2: Using formula (2), obtain the benchmark value of power supply coal consumption from the preset load rate, preset power supply coal consumption and preset load-power supply coal consumption change rate curves;

[0080] C0 = C t ×(1+f(x t )) (2);

[0081] Where C0 represents the baseline value of coal consumption for power supply; C t Indicates the preset coal consumption for power supply; x t Indicates the preset load factor; f(x) t This indicates the rate of change in coal consumption for power supply corresponding to the preset load rate.

[0082] In this embodiment, the preset load rate and preset coal consumption for power supply refer to the load rate and coal consumption for power supply during the same period of the heating unit's operation.

[0083] To make it easier to understand, the following examples are provided:

[0084] The coal consumption for power supply of a certain heating unit during the same period of operation is 286.97 g / MWh, and the load rate during the same period of operation is 69.1%. Substituting into formula (2) for calculation, 286.97 x (1 + (-0.916*0.6913 + 2.491*0.6912 - 2.1882*0.691 + 0.685)) = 292.34, and the benchmark value of coal consumption for power supply is 292.34 g / MWh.

[0085] In this embodiment, by using formula (2), the preset load rate and corresponding coal consumption for power supply of the heating unit are obtained, and the benchmark value of coal consumption for power supply is calculated by combining the preset load rate-coal consumption change rate curve, so that the initial value of coal consumption for power supply under the load rate obtained in real time of the heating unit can be calculated based on the benchmark value of coal consumption for power supply.

[0086] Optionally, step S200 above is specifically calculated in the following manner:

[0087] Using formula (3), the load factor, the preset load-power coal consumption change rate curve and the power coal consumption benchmark value are calculated to obtain the initial value of power coal consumption;

[0088] C r =C0×(1+f(x) r )) (3);

[0089] Among them, C r Indicates the initial value of coal consumption for power supply; x r f(x) represents the load factor; r () indicates the rate of change in coal consumption for power supply corresponding to the load factor.

[0090] To make it easier to understand, the following examples are provided:

[0091] The real-time monitoring system calculated the load rate of the heating unit to be 60.87%. Substituting this into formula (3), we get 292.34x(1+(0.916*0.60873+2.491*0.60872-2.1882*0.6087+0.685))=301.91, and the initial value of coal consumption for power supply is 301.91g / MWh.

[0092] In this embodiment, the initial value of power supply coal consumption is obtained by calculating the real-time load rate of the heating unit, the preset load-coal consumption change rate curve, and the power supply coal consumption benchmark value using formula (3). Since the initial value of power supply coal consumption is calculated based on the power supply coal consumption benchmark value, it is equivalent to providing a more accurate reference value, which reduces the error of the calculated initial value of power supply coal consumption and thus improves the accuracy of the calculated initial value of power supply coal consumption.

[0093] Optionally, step S300 above is specifically calculated in the following manner:

[0094] Using formula (4), the heat-to-power ratio of the heating unit and the adjustment coefficient of the standard coal consumption for power supply of the heating unit are calculated to obtain the corrected value of coal consumption for power supply.

[0095]

[0096] Among them, C j This indicates the correction value for coal consumption for power supply; β represents the heat-to-power ratio of the heating unit; β represents the standard coal consumption adjustment coefficient for the power supply unit.

[0097] It should be noted that, under heating conditions, the real-time coal consumption of the heating unit will be lower than that of the pure condensing unit under the same operating conditions. Therefore, the initial value of the calculated coal consumption for power generation is corrected, and the specific correction value is determined by the heat-to-power ratio of the heating unit and the adjustment coefficient of the standard coal consumption for heating.

[0098] To make it easier to understand, the following examples are provided:

[0099] The heat-to-power ratio of the heating unit is 14.6%, and the standard coal consumption adjustment coefficient of the heating unit is 1.5. Substituting into formula (4) for calculation, 0.146x 36x 1.5÷1000=7.884, the corrected value of coal consumption for power supply is 7.884g / MWh.

[0100] In this embodiment, the heat-to-electricity ratio of the heating unit and the adjustment coefficient of the standard coal consumption for power supply of the heating unit are calculated using formula (4) to obtain the correction value of the coal consumption for power supply, so as to correct the initial value of the calculated coal consumption for power supply, thereby improving the accuracy of the calculation of coal consumption for power supply.

[0101] Optionally, step S400 above is specifically calculated in the following manner:

[0102] Using formula (5), the initial value and the corrected value of coal consumption for power supply are calculated to obtain the actual value of coal consumption for power supply;

[0103] C = C r -C j (5);

[0104] Where C represents the actual value of coal consumption for power supply.

[0105] To make it easier to understand, the following examples are provided:

[0106] The initial value of coal consumption for power supply is 301.91 g / MWh, and the corrected value of coal consumption for power supply is 7.884 g / MWh. Substituting these values ​​into formula (5) for calculation, we get 301.91 - 7.884 = 294.026, and the actual value of coal consumption for power supply is 294.026 g / MWh.

[0107] In this embodiment, the initial value of power supply coal consumption and the correction value of power supply coal consumption are calculated using formula (5) to obtain the actual value of power supply coal consumption. This allows the initial value of power supply coal consumption to be corrected based on the correction value of power supply coal consumption, and finally the accurate power supply coal consumption is obtained.

[0108] Based on the same inventive concept, embodiments of the present invention also provide a power supply coal consumption calculation device 200.
