Description

Technical Field

[0001] The invention relates to a measurement optimization method for a distribution network, in particular to a method for accurately measuring the real-time carbon efficiency ratio of electric power equipment and its system in full-time and time-sharing service states. Background Art

[0002] This application involves the field of accurate measurement of real-time carbon efficiency of power equipment and its systems in full-time and part-time service. The main application scenarios include: the company's power distribution system, electrical transmission system, major energy-consuming equipment, coal mines and other key energy-consuming industries, etc.

[0003] Product carbon footprint detection refers to the sum of greenhouse gas emissions and greenhouse gas removals in the product system, expressed in carbon dioxide equivalent. Carbon efficiency refers to the ratio of carbon dioxide emissions generated by power equipment or systems during operation to the work done by them, and is an important indicator for evaluating the impact of power equipment or systems on the environment. At present, product carbon footprint indicators are generally used to evaluate the carbon emission intensity of products throughout their life cycle, but power equipment and its systems are energy-consuming equipment, and the emissions during the use phase account for more than 90% of their carbon emissions throughout their life cycle. Using carbon footprint to evaluate its carbon emission level does not take into account the work done, because the more work done, the more carbon emissions, so it is more scientific to use carbon efficiency to evaluate the carbon emission intensity of energy-consuming products. However, in most cases, products need to run uninterruptedly and cannot be shut down, so it is impossible to measure the carbon efficiency data of power equipment and its systems in service. The existing technology has the following problems: 1. At present, there is a large error in the calculation of carbon emissions of power equipment and its systems in the use phase; 2. There is an unmeasurable problem in the carbon efficiency of power equipment and its systems in full-time or part-time service.

[0004] In summary, real-time measurement of the carbon efficiency of products or systems can reflect the correlation between the work done by the products or systems and their carbon emissions, which is of practical application significance. In view of this, a measurement method for measuring the carbon efficiency of power equipment and its systems in full-time or part-time service is designed. Summary of the invention

[0005] The object of the present invention is to provide a method for accurately measuring the real-time carbon efficiency of electric power equipment and its system in full-time and time-sharing service states.

[0006] The following technical solutions are used to achieve this:

[0007] A method for accurately measuring the real-time carbon efficiency ratio of electric power equipment and its system in full-time and time-sharing service states comprises the following steps:

[0013] (6) Calculate the real-time carbon footprint of power equipment and its systems;

[0014] (7) Calculate the total real-time functional contribution of the product or system under test, specifically, calculate the total functional contribution based on the active electric energy consumed over a period of time;

[0015] (8) Calculate the real-time carbon efficiency of power equipment and its system. The specific calculation formula is as follows:

[0016] Calculate the product carbon efficiency ratio = product carbon footprint over a period of time / total functional contribution over a period of time.

[0017] Furthermore, step (6) calculates the real-time carbon footprint of the power equipment and its system, specifically:

[0018] 1) According to the active electric energy value consumed in a period of time, the carbon emissions during this period are calculated as the carbon emissions in the use phase;

[0019] 2) Calculate the total carbon footprint emissions of the tested product or system = carbon emission data in the raw material stage + carbon emission data in the production stage + carbon emission data in the use stage.

[0020] and,

[0021] The carbon emission data in step (2) also includes carbon emission data in the waste phase;

[0022] The total carbon footprint emissions of the tested product or system calculated in step (6) = carbon emissions data of the raw material stage + carbon emissions data of the production stage + carbon emissions data of the use stage + carbon emissions data of the disposal stage.

[0023] 4. According to the method for accurately measuring the real-time carbon efficiency of power equipment and its system in full-time and time-sharing service states as described in claim 1, it is characterized in that the operation mode of the measured product or system is divided into full-time and time-sharing, full-time is uninterrupted operation; time-sharing includes periodic operation and irregular operation.

[0056] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] The carbon efficiency data of products is obtained by investigating the ratio of carbon emissions of products in their entire life cycle, including raw material acquisition, product production, transportation, use, and disposal, to the work done by the product or system. The data is obtained by selecting typical products based on the assumptions of use conditions and lifespan. Due to the differences in service status, load, power grid quality, service frequency and cycle of full-time and part-time service equipment and their systems, the estimation error of using typical fixed data in different application scenarios is large, so the following measurement method is specially proposed.

[0058] A method for accurately measuring the real-time carbon efficiency ratio of power equipment and its system in full-time and time-sharing service states, the specific steps are as follows:

[0059] (1) Determine the product functional unit of the product or system under test, see Figure 1 As shown, confirm the attached Figure 1 The product or system under test, such as a frequency converter, an electrical drive system, etc.

[0060] The product functional units that need to be determined specifically include: determining the rated parameter information of the product or system being tested, determining the working conditions and load parameters of the product or system being tested;

[0061] (2) Calculate carbon emission data except for the use stage. Currently, product carbon emission accounting is divided into full life cycle or half life cycle. It is necessary to extract the actual demand and write the carbon emission data of the tested product or system in the raw material stage, production stage, and waste stage (if necessary) to provide data for the subsequent measurement of the carbon footprint and carbon efficiency of the product or system;

[0062] (3) Measure the active power of the product or system under test. The product or system under test consumes energy during operation, and the active power consumed should be measured. Active power is the main parameter of the equipment's operating level and is used for subsequent calculations of the energy consumed.

[0063] (4) Measure the operating cycle of the product or system under test, specifically determine whether the product or system under test is full-time or part-time, and calculate the integral statistics of the operating time of the product or system under test;

[0064] The operation modes of power equipment or systems are divided into full-time and time-sharing. Full-time means uninterrupted operation, such as coal mines and offshore oil platforms; time-sharing means periodic operation, irregular operation, etc.

[0065] It is necessary to determine the operation cycle and then calculate the carbon emission level within this operation cycle;

[0066] (5) Measure the active energy value of the product or system under test, and calculate the energy consumption data within the operating cycle through the integral statistics of active power and time;

[0067] (6) Calculate the real-time carbon footprint of power equipment and its systems,

[0068] 1) According to the active electric energy value consumed in a period of time, the carbon emissions during this period are calculated as the carbon emissions in the use phase;

[0069] 2) Calculate the total emissions (product carbon footprint) = carbon emissions data at the raw material stage + carbon emissions data at the production stage + carbon emissions data at the use stage + carbon emissions data at the disposal stage (if applicable);

[0070] (7) Calculate the total real-time functional contribution of the product or system under test, specifically, calculate the total functional contribution based on the active electric energy consumed over a period of time;

[0071] (8) Calculate the real-time carbon efficiency of power equipment and its systems;

[0072] Calculate the product carbon efficiency ratio = product carbon footprint over a period of time / total functional contribution over a period of time.

[0073] This method takes the service conditions and service cycles of power equipment and its systems as variables and inputs them into the real-time carbon efficiency test method, avoiding the assumption of typical conditions without considering the differences in carbon efficiency data under harmonic, reactive power and instantaneous high current conditions, and effectively improving the carbon efficiency measurement accuracy in their respective specific service scenarios.

Since power equipment and its systems consume or transmit electric energy when in service, and the amount of data in this stage increases rapidly with the increase of service time, its carbon emissions will eventually gradually occupy a relatively high proportion of the entire life cycle.

[0078] The data processing module analyzes and processes the collected data according to a preset algorithm and calculates the carbon efficiency of the tested product or system.

[0079] The display module displays the calculation results to the user in real time so that the user can understand the carbon efficiency of the power equipment or system in a timely manner.
