Description

Technical Field

[0001] This invention belongs to the technical field of core indicator evaluation for power production and operation, and specifically relates to a method, system, equipment and medium for calculating the annual cumulative number of hours exceeding the standard for pollutants. Background Technology

[0002] Pollutant emissions are a core evaluation indicator for the production and operation of power generation enterprises, and whether pollutant emissions meet the standards is one of the fundamental factors in measuring the economic benefits of power generation enterprises. At present, most power generation groups calculate the hourly value of pollutant emissions through the real-time pollutant emission data of their respective power generation enterprises, and there is no annual statistics on the exceedance of standards. When it is necessary to calculate the annual pollutant emission situation, it is necessary to manually export the pollutant data for the whole year for calculation, which is a complicated and costly process. Summary of the Invention

[0003] To address the technical problems existing in the prior art, this invention provides a method, system, equipment, and medium for calculating the annual cumulative number of hours exceeding the standard for pollutants, thereby solving the technical problem that the statistical calculation process is difficult and costly when power generation companies compile annual pollutant emissions statistics.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] This invention provides a method for calculating the annual cumulative number of hours exceeding pollutant standards, comprising the following steps:

[0006] Obtain pollutant emission data from all generating units within all power plants;

[0007] Based on the pollutant emission data of each unit in all power generation enterprises, calculate the hourly average pollutant emission of each unit in all power generation enterprises.

[0008] The hourly average pollutant emissions of all power generation units are compared with the preset unit emission standards to obtain the hourly pollutant emission status of each unit in all power generation enterprises.

[0009] Based on the hourly pollutant emission status of each unit in all power generation enterprises, the preset unit emission status labels are written into the hourly pollutant emission status of each unit in all power generation enterprises to obtain the hourly pollutant emission status value of each unit in all power generation enterprises.

[0010] Based on the hourly pollutant emission status values ​​of each unit of all power generation enterprises, the number of hours of pollutant emissions exceeding the standard for each unit of all power generation enterprises throughout the year can be obtained.

[0011] Based on the number of hours of pollutant emissions exceeding standards for each unit of all power generation enterprises throughout the year, the cumulative number of hours of pollutant emissions exceeding standards for the power generation group and its branches are calculated separately.

[0012] Furthermore, the pollutant emission data includes sulfur dioxide emission data, nitrogen oxide emission data, and particulate matter emission data.

[0013] Furthermore, based on the pollutant emission data of each unit within all the power generation enterprises, the process of calculating the hourly average pollutant emissions of each unit in all the power generation enterprises is as follows:

[0014] Determine whether the unit is running. If so, calculate the hourly average pollutant emission of the unit based on the pollutant emission data of all units of all power generation enterprises. If not, record the hourly average pollutant emission of the unit as 0.

[0015] The process of calculating the hourly average pollutant emissions of the computer group based on the pollutant emission data of each unit of all the power generation enterprises is as follows:

[0016] Based on the real-time pollutant emission data of the unit, one pollutant emission data point is generated every 10 seconds, resulting in 360 pollutant emission data points per hour. The 360 ​​pollutant emission data points per hour are then weighted and averaged to obtain the hourly average pollutant emission of the unit.

[0017] Furthermore, the process of comparing the hourly average pollutant emissions of all power generation units with preset unit emission standards to obtain the hourly pollutant emission status of each unit within all power generation enterprises is as follows:

[0018] Determine if the unit is running. If yes, proceed to the emission status determination step; otherwise, record the hourly pollutant emission status of the corresponding unit as shut down.

[0019] The emission status determination steps are as follows:

[0020] The hourly average pollutant emissions of the unit are compared with the preset unit emission standards. If the hourly average pollutant emissions of the unit are greater than the preset unit emission standards, the hourly pollutant emission status of the corresponding unit is recorded as exceeding the standard; otherwise, the hourly pollutant emission status of the corresponding unit is recorded as not exceeding the standard.

[0021] Furthermore, the preset unit emission status labels are: no exceedance label, exceedance label, and shutdown label; wherein, no exceedance label is 0, exceedance label is 1, and shutdown label is 4;

[0022] The process of writing the preset unit emission status labels into the hourly pollutant emission status of each unit in all power generation companies to obtain the hourly pollutant emission status values ​​of each unit in all power generation companies is as follows:

[0023] The "not exceeding the standard" label is written into the pollutant emission hours of each unit in the power generation enterprise whose pollutant emission status is "not exceeding the standard".

[0024] The above-standard label will be written into the pollutant emission hours of each unit in the power generation enterprise whose pollutant emission status is above standard.

[0025] The shutdown tag is written to the hourly pollutant emission status of each unit in the power generation enterprise that is in a shutdown emission status.

[0026] Furthermore, based on the hourly emission status values ​​of pollutants from each unit of all power generation enterprises, the process of obtaining the number of hours of pollutant emissions exceeding the standards for each unit throughout the year is as follows:

[0027] The pollutant emission hours of each unit with a label indicating excessive emissions were summed up to obtain the total number of hours of excessive pollutant emissions for all units in all power generation companies throughout the year.

[0028] Furthermore, the annual cumulative number of hours exceeding the pollutant standard, t1, for the branch company is:

[0029]

[0030] The annual cumulative number of hours exceeding pollutant standards (t2) for the power generation group is:

[0031]

[0032] This invention also provides a system for calculating the annual cumulative number of hours exceeding pollutant standards, comprising:

[0033] The data acquisition module is used to acquire pollutant emission data from all generating units within all power generation companies;

[0034] The hourly average module is used to calculate the hourly average pollutant emissions of each unit in all power generation enterprises based on the pollutant emission data of each unit in all power generation enterprises.

[0035] The emission status judgment module is used to compare the hourly average pollutant emission values ​​of all power generation units with the preset unit emission standards to obtain the hourly pollutant emission status of each unit in all power generation enterprises.

[0036] The tag module is used to write the preset unit emission status tags into the pollutant emission hours of each unit in all power generation enterprises according to the hourly pollutant emission status of each unit in all power generation enterprises, so as to obtain the hourly pollutant emission status value of each unit in all power generation enterprises.

[0037] The module for counting hours of excessive emissions from generating units is used to obtain the number of hours of excessive emissions from each generating unit of all power generation companies throughout the year, based on the hourly emission status values ​​of pollutants from each generating unit of all power generation companies.

[0038] The results output module is used to calculate the annual cumulative number of hours of pollutant emissions exceeding the standards for each power generation group and its branches, based on the number of hours of pollutant emissions exceeding the standards for each unit of all power generation enterprises throughout the year.

[0039] This invention also provides a device for calculating the annual cumulative number of hours exceeding the standard for pollutants, comprising:

[0040] Memory, used to store computer programs;

It collects real-time pollutant emission data and real-time power generation data from the metering systems of various power generation companies. The system calculates the hourly average pollutant emission using the real-time power generation data and pollutant emission data, then compares it with the pollutant emission standards of each plant.

[0045] Figure 1 This is a flowchart illustrating the method for calculating the annual cumulative number of hours exceeding the standard for pollutants as described in the embodiment. Detailed Implementation

[0046] To make the technical problems solved by the present invention, the technical solutions, and the beneficial effects clearer, the following specific embodiments provide a further detailed description of the present invention. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of the invention.

[0047] This invention provides a method for calculating the annual cumulative number of hours exceeding pollutant standards, comprising the following steps:

[0048] Step 1: Obtain pollutant emission data for each unit within all power generation enterprises; the pollutant emission data includes sulfur dioxide emission data, nitrogen oxide emission data, and particulate matter emission data.

[0049] Step 2: Based on the pollutant emission data of each unit in all power generation enterprises, calculate the hourly average pollutant emissions of each unit in all power generation enterprises; the specific process includes the following steps:

[0050] To determine whether the unit is operating, if so, calculate the hourly average pollutant emissions of the unit based on the pollutant emission data of all units of the power generation companies; otherwise, record the hourly average pollutant emissions of the unit as 0. Specifically, the process of calculating the hourly average pollutant emissions of the unit based on the pollutant emission data of all units of the power generation companies involves: generating one pollutant emission data point every 10 seconds based on the real-time pollutant emission data of the unit, resulting in 360 pollutant emission data points per hour; and performing a weighted average on these 360 ​​pollutant emission data points per hour to obtain the hourly average pollutant emissions of the unit.

[0051] Taking the calculation of the hourly average pollutant emissions of a certain unit as an example, the specific steps include:

[0052] Acquire real-time power generation and pollutant emissions data of the generating unit;

[0053] If the real-time power generation of the unit is refreshed normally and the real-time power value of the unit is less than 15, then write data 0 as a 10-second emission data and end the calculation.

[0054] If the real-time power of the unit is refreshed normally, and the real-time power value of the unit is greater than 15 and the real-time pollutant emission data is greater than 0, then the latest value of the real-time pollutant data is written as a 10-second emission data, and the calculation ends.

[0055] If the real-time power of the unit is refreshed normally, and the real-time power value of the unit is greater than 15 and the real-time pollutant emission data is less than 0, then write data 0 as 10 seconds of emission data and end the calculation.

[0056] If the real-time power of the unit is not refreshed normally within three hours, then write data 0 as a 10-second emission data and include it in this calculation;

[0057] Repeat the above operation to obtain 360 10-second emission data points within one hour, and then perform a weighted average of the 360 ​​10-second emission data points to obtain the hourly average of the pollutant emissions from the unit.

[0058] Step 3: Compare the hourly average pollutant emissions of all power generation units with the preset unit emission standards to obtain the hourly pollutant emission status of each unit within all power generation enterprises; the specific process is as follows:

[0059] Determine if the unit is running. If yes, proceed to the emission status determination step; otherwise, record the hourly pollutant emission status of the corresponding unit as shut down.

[0060] The emission status determination steps are as follows:

[0061] The hourly average pollutant emissions of the unit are compared with the preset unit emission standards. If the hourly average pollutant emissions of the unit are greater than the preset unit emission standards, the hourly pollutant emission status of the corresponding unit is recorded as exceeding the standard; otherwise, the hourly pollutant emission status of the corresponding unit is recorded as not exceeding the standard.

[0062] Step 4: Based on the hourly pollutant emission status of each unit in all power generation enterprises, write the preset unit emission status tags into the hourly pollutant emission data of each unit in all power generation enterprises to obtain the hourly pollutant emission status values ​​of each unit in all power generation enterprises; wherein, the preset unit emission status tags are a "not exceeding the standard" tag, a "exceeding the standard" tag, and a "shutdown" tag; wherein, the "not exceeding the standard" tag is 0, the "exceeding the standard" tag is 1, and the "shutdown" tag is 4.

[0063] The process of writing the preset unit emission status labels into the hourly pollutant emission status of each unit in all power generation companies to obtain the hourly pollutant emission status values ​​of each unit in all power generation companies is as follows:

[0064] The "not exceeding the standard" label is written to the hourly pollutant emission status of each unit in the power generation enterprise where the pollutant emission status is "not exceeding the standard"; the "exceeding the standard" label is written to the hourly pollutant emission status of each unit in the power generation enterprise where the pollutant emission status is "exceeding the standard"; the "shutdown" label is written to the hourly pollutant emission status of each unit in the power generation enterprise where the pollutant emission status is "shutdown".

[0065] Step 5: Based on the hourly pollutant emission status values ​​of each unit in all power generation enterprises, obtain the total number of hours of pollutant emissions exceeding the standard for each unit in all power generation enterprises throughout the year; specifically, sum up the pollutant emission hours of each unit with the "exceeding standard" label in all power generation enterprises to obtain the total number of hours of pollutant emissions exceeding the standard for each unit in all power generation enterprises throughout the year.

[0066] Step 6: Based on the number of hours of pollutant emissions exceeding standards for each unit of all power generation enterprises throughout the year, calculate the cumulative annual number of hours of pollutant emissions exceeding standards for the power generation group and its branches respectively; among which, the cumulative annual number of hours of pollutant emissions exceeding standards for the branches is t1:

[0067]

[0068] The annual cumulative number of hours exceeding pollutant standards (t2) for the power generation group is:

[0069]

[0070] The method for calculating the annual cumulative number of hours exceeding pollutant standards described in this invention can automatically calculate the pollutant exceedance situation of each thermal power unit in the previous hour, and then perform weighted calculation based on the rated installed capacity of the units of the group and each branch company. This enables real-time statistics of the annual cumulative number of hours exceeding pollutant standards for each branch company and the group, replacing the original manual reporting and calculation of the annual number of hours exceeding pollutant standards.

[0102] Step 6: Based on the number of hours of pollutant emissions exceeding standards for each unit of all power generation enterprises throughout the year, calculate the cumulative number of hours of pollutant emissions exceeding standards for the power generation group and its branches respectively; calculate the number of hours of emissions exceeding standards for each unit every hour; then, based on the branch and group dimensions, calculate the annual number of hours of emissions exceeding standards for the units of the power plants under the branch by weighting the installed capacity of the units. Using the installed capacity weighted average algorithm is fairer to all units under the group and the calculation results are more accurate and reliable.
