Description

Technical Field

[0001] This invention relates to the field of power grid construction technology, and in particular to an environmental assessment method for the environmental impact of power grid construction projects. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Currently, with the continuous progress of society and the economy, and to meet people's growing living needs, power system construction is gradually spreading across various regions. However, the conflicts between these projects and the surrounding environment are becoming increasingly apparent. To protect the ecological environment, environmental assessments of power grid construction projects are necessary. Existing project assessment methods often employ multi-indicator comprehensive evaluation, which involves establishing an indicator system, determining the weights of each objective, and then calculating the assessment results. However, in the environmental assessment process for power grid construction projects, most considerations focus on the environmental impact of the project itself, with few studies addressing the sensitivity of different environmental regions. Since the environmental quality baselines and environmental impact requirements vary across different environmental regions, how to conduct environmental assessments based on the compatibility between the environmental region and the project itself has become an urgent technical problem to be solved. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an environmental assessment method for the environmental impact of power grid construction projects. By deeply exploring the correlation between different projects and different environments, a personalized matching relationship between the environment and the project is established. Based on this matching relationship, an environmental assessment system is established to obtain environmental assessment results, thereby achieving a more reasonable and scientific environmental assessment.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] This invention provides an environmental impact assessment method for power grid construction projects, comprising the following steps:

[0007] Obtain the construction information of the project to be evaluated, extract all attribute information that has an impact on the environment from the construction information, and preprocess the extracted attribute information;

[0008] Obtain information about the environmental area where the project is located and determine environmental objectives;

[0009] The correlation between attribute information and environmental objectives is analyzed, and the attribute information with the strongest correlation is regarded as the main influencing factor, while all other influencing factors are regarded as secondary influencing factors.

[0010] The primary and secondary influencing factors are assessed according to the preset environmental standards. The project to be assessed is considered qualified only when all primary and secondary influencing factors are qualified.

[0011] Furthermore, prior to the assessment, projects to be assessed are directly screened based on the current ecological protection red line and environmental quality baseline of the region.

[0012] Furthermore, the specific steps for extracting all attribute information that has an impact on the environment from the construction information are as follows:

[0013] Search for environment-related information in the entire construction history of the project to be evaluated;

[0014] Organize environmental information and remove duplicate and incorrect information;

[0015] The sorted information is categorized by attributes, and the duration and intensity of each attribute's impact on the environment are recorded.

[0016] Furthermore, the specific steps for searching for environment-related information include:

[0017] Directly search for textual information and data that have an impact on the environment using semantic search methods;

[0018] Indirectly search for environmental impacts in the remaining text information and data using deductive reasoning.

[0019] Furthermore, the preprocessing step involves normalizing the extracted attribute information.

[0020] Furthermore, based on the geographical conditions and regional functions of the environmental area, environmental weaknesses are identified as environmental targets.

[0021] Furthermore, the environmental objectives can be single or multiple. When there are multiple environmental objectives, the project to be evaluated is evaluated for each objective.

[0022] Furthermore, the specific steps for performing correlation analysis between attribute information and environmental objectives are as follows:

[0023] The correlation probability is calculated based on the degree of direct impact of attribute information on environmental targets;

[0024] Sort the attribute information according to the probability of association;

[0025] The higher the correlation probability, the stronger the correlation. The attribute information with the highest correlation probability is taken as the main influencing factor.

[0026] Furthermore, the specific steps for assessing the primary and secondary influencing factors according to the preset environmental standards are as follows:

[0027] Establish a project simulation model based on the project to be evaluated;

[0028] The project simulation model is used to predict the impact of the main influencing factors and to determine whether the degree of impact of the main influencing factors within a specified time period meets the preset environmental standards.

[0029] The influence of all secondary influencing factors is scored and the scores are accumulated. The accumulated scores are compared with the preset threshold to determine whether the preset environmental standards are met.

[0030] Furthermore, when the evaluation results of the main or secondary influencing factors are unsatisfactory, optimization suggestions are generated based on the evaluation results.

[0031] The above one or more technical solutions have the following beneficial effects:

[0032] This invention discloses an environmental impact assessment method for power grid construction projects. By identifying the most vulnerable and critical environmental targets based on the characteristics of different environmental regions, and through correlation analysis, it determines the factors with the greatest impact on these targets and the remaining secondary factors, analyzing them separately. This results in a more accurate environmental impact assessment of power grid construction projects. The method is widely applicable, not limited by changes in environmental regions, and can be flexibly adjusted to suit local environmental standards, leading to more scientific and reasonable assessment results.

[0033] Advantages of additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0038] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention.

Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0039] Example:

[0040] This invention provides an environmental impact assessment method for power grid construction projects, such as... Figure 1 As shown, it includes the following steps:

[0041] S1: Obtain the construction information of the project to be evaluated, extract all attribute information that has an impact on the environment from the construction information, and preprocess the extracted attribute information.

[0042] S2: Obtain information about the environmental area where the project is located and determine environmental objectives.

[0043] S3: Conduct a correlation analysis between attribute information and environmental objectives, and identify the attribute information with the strongest correlation as the primary influencing factor, while all other influencing factors are considered secondary influencing factors.

[0044] S4: Evaluate the primary and secondary influencing factors according to the preset environmental standards. The project to be evaluated is considered qualified only when all primary and secondary influencing factors are qualified.

[0045] In S1, before the assessment, the projects to be assessed are directly screened based on the current ecological protection red line and environmental quality baseline of the environmental area. Projects that touch the ecological protection red line and environmental quality baseline are directly deemed unqualified.

[0046] In one specific implementation, the steps for extracting all environmentally impacting attribute information from construction information are as follows:

[0047] Search for environment-related information within the entire construction lifecycle of the project to be evaluated. This includes direct and indirect search methods: using semantic search to directly search textual information and data that may have environmental impacts, such as extracting keywords directly related to environmental impacts like electromagnetic interference and pollution. Using inductive methods to indirectly search for environmental impacts within other textual information and data, for example, by searching and extracting statements that may have environmental impacts using existing knowledge graphs or inductive models.

[0048] Organize the environmental information and remove duplicate and incorrect information.

[0049] The processed information is categorized by attribute, and the duration and intensity of each attribute's environmental impact are recorded. In this embodiment, the attribute information is categorized into noise interference, radio interference, land impact, and vegetation impact based on the type of impact. Specifically, it can be further subdivided into more detailed categories; for example, land impact includes land area, soil compaction, and land pollution, while vegetation impact includes climate impact, vegetation cover impact, and plant diversity impact. The categories can be set according to actual needs.

[0050] In one specific implementation, the preprocessing step involves normalizing the extracted attribute information and quantifying its influence intensity.

[0051] In S2, environmental weaknesses are identified as environmental targets based on the geographical conditions and regional functions of the environmental region.

[0052] Specifically, based on the geographical conditions and regional functions of the environmental region, the specific manifestations of environmental weaknesses are obtained. By querying the existing database, the geographical conditions and regional functions of the environmental region are obtained, such as residential areas in plateau regions and ecological protection areas in desert regions. Environmental weaknesses are then matched, including residents, animals, plants, special landforms, geology, etc. Environmental objectives can be set as single or multiple objectives as needed. When there are multiple environmental objectives, the project to be evaluated is evaluated for each objective.

[0053] In S3, the specific steps for performing correlation analysis between attribute information and environmental objectives are as follows:

[0054] The correlation probability is calculated based on the degree of direct impact of attribute information on environmental targets. The calculation formula is as follows:

[0055]

[0056] Among them, P mn T represents the degree of influence of the m-th attribute information on n environmental targets. mn T represents the association value between attribute information and environmental objectives. m For attribute information values, Tn This represents the environmental target value. Its associated values, attribute information values, and environmental target values ​​can be calculated using methods such as grey relational analysis.

[0057] In one specific implementation, the formula for calculating the association value between attribute information and environmental targets using the grey relational analysis method is as follows:

[0058]

[0059] Where, ε m (n) is the correlation coefficient between the m-th attribute information and the n-th environmental target, T m For attribute information values, T n The target environmental value is ρ, which represents the resolution coefficient and has a value of 0.5.

[0060]

[0061] Where, ε m (n) represents the correlation coefficient between the m-th attribute and the n-th environmental target, where M is the number of attributes, m is the m-th attribute, n is the n-th environmental target, and T is the correlation coefficient between the m-th attribute and the n-th environmental target. mn This represents the association value between attribute information and environmental targets.

[0062] In this embodiment, attribute information and environmental targets are determined and numbered. Attribute information includes noise interference, radio interference, land area, soil compaction, land pollution, climate impact, vegetation cover impact, and plant diversity impact. Environmental targets include residents, animals, plants, unique landforms, and geology.

[0063] It should be noted that both the attribute information value and the environmental target value have been dimensionless and assigned a score of 1-100 according to existing power project construction regulations and data experience. The higher the attribute information value score, the stronger the impact of the current attribute in the project, and the higher the environmental target value, the more important the current environmental target is to the region.

[0064] Attribute information is sorted according to its correlation probability. A higher correlation probability indicates a stronger correlation, which in turn indicates a greater impact of the attribute information on the current regional environmental objectives. The attribute information with the greatest impact on environmental objectives can be obtained through the above calculation process. For example, when the environmental objective is residents, the attribute information with the highest correlation probability is noise, followed by pollution. However, when the environmental objective is vegetation, the attribute information with the highest correlation probability is vegetation cover caused by land occupation, followed by plant diversity. Therefore, different environmental objectives correspond to different regional weaknesses, a point that existing evaluation systems do not consider. The attribute information with the highest correlation probability is then used as the primary influencing factor.

[0065] In S4, the specific steps for assessing the primary and secondary influencing factors according to the preset environmental standards are as follows:

[0066] Establish a project simulation model based on the project to be evaluated;

[0067] Using project simulation models and existing simulation prediction technologies, the impact of key influencing factors is predicted to determine whether their influence levels within a specified time period meet preset environmental standards. For example, long-term impacts such as soil compaction and biodiversity may not be immediately apparent, and various indicators may generally meet preset environmental standards throughout the construction cycle. However, over time, some impacts will subtly alter the existing ecological environment. Therefore, it is necessary to predict the impacts months, years, or even decades after project construction to determine whether the project truly meets the preset environmental standards.

[0068] In one specific implementation, a digital twin model is used to simulate the entire project construction. A convolutional neural network model is constructed, and relevant data on influencing factors are obtained from an existing database, divided into a training set and a test set. The convolutional neural network model is trained using the training set to obtain prediction results. Specifically, the relevant data on influencing factors includes the types of influencing factors, the duration of their influence, and the impact results within a given time period. Existing machine learning methods such as deep learning and transfer learning can be used for the learning process. The trained model, obtained through continuous training and testing, can predict the impact of influencing factors on the project construction in this embodiment within a specified time period, and the prediction results are displayed intuitively through the simulation model.

[0069] The impact of all secondary influencing factors is scored, and the scores are accumulated. The accumulated scores are then compared with preset thresholds to determine whether the preset environmental standards are met. For secondary factors, thresholds and levels can be preset based on actual conditions or expert experience. The impact of the corresponding secondary factor (previously categorized, recorded, and quantified) is accumulated with its corresponding level score to conduct a secondary influencing factor assessment. In this way, both primary and secondary influencing factors are included in the assessment, which is not only comprehensive but also sets up primary and secondary influencing factors according to different environmental objectives, making it both targeted and comprehensive.

[0070] In one specific implementation, when the assessment results of the primary or secondary influencing factors are unsatisfactory, an optimization proposal is generated based on the assessment results. Specifically, based on the unsatisfactory item, optimization measures to reduce its impact are searched in the existing solution library, and simulation is performed on the optimization measures. If the simulation is satisfactory, an optimization proposal is generated.

[0071] Those skilled in the art will understand that the modules or steps of the present invention described above can be implemented using general-purpose computer devices. Optionally, they can be implemented using computer-executable program code, thereby allowing them to be stored in a storage device for execution by a computer device, or they can be fabricated as separate integrated circuit modules, or multiple modules or steps can be fabricated as a single integrated circuit module. The present invention is not limited to any particular combination of hardware and software.

[0072] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
