Description

[Technical field]

[0001] The present invention relates to the technical field of carbon emission calculation of a thermal power unit, in particular to a method for calculating carbon emission of a thermal power unit, an apparatus for calculating carbon emission of a thermal power unit, an electronic device, and a readable storage medium. [Background technology]

[0002] At present, the proportion of electrical energy generated by thermal power generation in domestic and industrial electricity consumption remains high, so the investigation of carbon emissions from thermal power generation units is of great significance. Generally, carbon emissions are measured using the accounting method and the continuous emission monitoring system method. The continuous emission monitoring system method has already gained a certain foundation, but the existing technology relies on the principle of "accounting as the main, monitoring as the secondary", and at present, the power generation industry adopts the accounting method to quantify carbon emissions. Among them, calculating the carbon emissions of thermal power generation units based on energy consumption is one of the accounting methods.

[0003] There are many research methods and contents for the energy consumption of traditional coal-fired power generation units, and the calculation method is mature and many achievements have been made, but the calculation method of energy consumption has been basically agreed upon. The direct balance statistical method has a large calculation error, and it is difficult to avoid or reduce the error by better means or methods, so the indirect balance calculation method is usually used to determine and evaluate the energy consumption of the unit. The indirect balance calculation method calculates the steam turbine heat consumption, boiler efficiency, in-house rate, and pipeline efficiency under a certain load condition through performance testing to calculate the test coal consumption under that load, and obtains the corrected energy consumption after correcting the boundary conditions to the design boundary conditions through correction calculation, that is, the standard energy consumption of the unit. Based on the research of energy consumption, the operating energy consumption of the unit at a specific load point is obtained by calculating the influence coefficient of the energy consumption caused by the deviation between the actual boundary conditions and the design value, and the carbon emission result of the thermal power generation unit at this load is obtained, and the carbon emission of the unit in a specific period is obtained by weighting statistics. However, existing calculation methods do not take into account the difference between daily operating values ​​and design parameter values, or the carbon content of the coal actually burned out, resulting in inaccurate calculations of carbon emissions. Summary of the Invention [Problem to be solved by the invention]

[0026] Specifically, during the operation of a thermal power generating unit in a certain operation period, its operation load usually changes linearly, i.e., as the operation time passes, its operation load increases or decreases, and the operation load does not jump over time. In step 102, the step of determining all characteristic load points of the thermal power generating unit in the total operation load section based on the total operation load section of the thermal power generating unit and the preset basic load point can be understood as each characteristic load point corresponds to one operator load section of the thermal power generating unit, and all operator load sections are combined to obtain a complete total operation load section.

[0027] Further, the step of determining all the characteristic load points of the thermal power generation units in the total operating load section based on the total operating load section and the preset basic load point of the thermal power generation units includes: If the minimum operating load within the total operating load section is equal to or greater than the preset basic load point, Determine both the minimum and maximum operating loads within the total operating load section as load points; Starting from the preset base load point, sequentially determine load points other than the load points corresponding to the minimum and maximum operating loads within the total operating load section according to a first preset interval; determining an average load between two adjacent load points among all load points in the total operating load section as a characteristic load point; If the maximum operating load within the total operating load section is equal to or lower than the preset basic load point, Determine both the minimum and maximum operating loads within the total operating load section as load points; Starting from the preset basic load point, sequentially determine load points other than the load points corresponding to the minimum and maximum operating loads within the total operating load section according to a second preset interval; determining an average load between two adjacent load points among all load points in the total operating load section as a characteristic load point; If the preset basic load point is within the total operating load section, A preset basic load point, a minimum operating load within a total operating load section, and a maximum operating load are all determined as load points; Starting from the preset basic load point, sequentially determine load points other than the basic load point and the load point corresponding to the maximum operating load between the preset basic load point and the load point corresponding to the maximum operating load in the total operating load section according to a first preset interval; Using the preset basic load point as a starting point, determine a load point other than the basic load point and the load point corresponding to the minimum operating load between the preset basic load point and the load point corresponding to the minimum operating load in the total operating load section according to a second preset interval; and determining, as a characteristic load point, an average load of every two adjacent load points among all the load points within the total operating load section.

[0029] Specifically, in this embodiment, a case where 55% load is the preset basic load point is taken as an example, the first preset amount is set to 5% of the reference test load, and the total operating load range of the thermal power generation unit is 30% to 50%. In this case, if the maximum operating load of 50% is less than the basic load point of 55%, first, the minimum operating load of 30% and the maximum operating load of 50% are determined as load points, and the maximum load p is determined based on the preset standard load point. max From minimum load p min All load points p in the load section m Determine one load point for every 5% increment until obtaining 50%, 45%, 40%, and 35% load. Determine all characteristic load points within the total load interval, and (p n +p n-1 ) / 2 is the characteristic load, and the characteristic load includes the characteristic load point of 47.5%, the characteristic load point of 42.5%, and the characteristic load point of 37.5%.
