[0054] Reference Figure 1 An embodiment of the present invention provides a method for quality control and evaluation of mainnet construction, the method specifically including:

[0055] S101, Obtain information on the expected construction projects of the main distribution network.

[0056] S102, create a main distribution network construction project management and control model based on the expected construction project information of the main distribution network, and evaluate the overall quality of the main distribution network construction project based on the main distribution network construction project management and control model.

[0057] S103, based on the expected construction project information of the main distribution network, the main distribution network construction project area is divided into several sub-project areas, and the construction quality of each sub-project area is evaluated according to the principal component analysis method.

[0058] In this embodiment, engineering information from the planning, design, construction, acceptance, and commissioning stages of the main distribution network is collected, including time nodes, cost budgets, and plans. Overall, a Petri net model is used to create a management and control model for the main distribution network construction project. With planning, design, construction, acceptance, and commissioning as stages, corresponding states are established, and transition events are set to represent the transitions between stages. Project events and weights are assigned to each transition event, constructing a model that makes the overall quality assessment more systematic and organized. Locally, the main distribution network construction project area is divided into several sub-project areas, for example, by geographical location or function. Construction factors for each sub-project area are obtained, such as personnel, equipment, laying, accidents, and management. Principal component analysis is performed using covariance matrices, eigenvalues, and eigenvectors to reduce dimensionality and obtain quality assessment results. This allows for a more comprehensive and objective evaluation of the sub-project areas of the main distribution network, helping to identify and resolve quality problems early and improve the overall project quality.

[0059] In step S102 above, the step of creating a main distribution network construction project management and control model based on the expected construction project information of the main distribution network specifically includes:

[0060] Based on the expected construction project information of the main distribution network, several expected construction project stages of the main distribution network are set up. The several expected construction project stages of the main distribution network include the planning stage, design stage, construction stage, acceptance stage and trial operation stage.

[0061] Several states are set in each phase of the expected construction project of the main power distribution network;

[0062] Several transition events are set between several states;

[0063] Several project events and a corresponding weight are set for each of the aforementioned transition events;

[0064] Based on the relationships between the pre-set construction project stages, several states, several transition events, and several project events of the main distribution network, a management and control model for the main distribution network construction project is established using a Petri net model.

[0065] In this embodiment, such as Figure 2 As shown, each stage of the main distribution network construction project includes states P1 to PN. After state P1, there are transition events T1, T2, T3, and T4. Each transition event leads to a different state, finally converging to transition event T4, and then migrating from TN to the last state PN of that stage. Each transition state contains project events A, A2, A3, A4, ..., AN. Each project event has a corresponding weight, which determines the progress ratio of each project event. When the current state meets the corresponding progress of each project event of a certain transition event, it can migrate to the next state. By setting the weights, the impact of each project event on the overall construction project can be assessed more accurately, improving the accuracy of quality control, thereby enhancing the visualization and systematic nature of the main distribution network construction project management.

[0066] Furthermore, the method also includes: in the main distribution network construction project management and control model, setting corresponding main distribution network expected construction project time and main distribution network expected construction project cost for each main distribution network expected construction project stage and each state.

[0067] In this embodiment, by setting the engineering time and cost, comprehensive control over the entire main distribution network construction project is achieved. The engineering time of each project stage can be evaluated in real time to ensure that the project proceeds as planned. At the same time, by setting the weights of the Petri net model, the cost impact of each project event can be weighed, which helps with cost control.

[0068] Furthermore, the assessment of the overall quality of the main distribution network construction project based on the main distribution network construction project management and control model specifically includes:

[0069] Real-time acquisition of actual construction project information of the main distribution network; by comparing the main distribution network construction project management model with the actual construction project information of the main distribution network, the deviation degree of the main distribution network construction project is obtained.

[0070] The overall quality of the current main and distribution network construction project is determined based on the deviation of the main and distribution network construction project.

[0071] Specifically, obtaining the deviation degree of the main distribution network construction project by comparing the main distribution network construction project management model with the actual construction project information of the main distribution network includes:

[0072] The actual construction time, cost, stage, and status of the current main distribution network construction project are obtained from the actual construction project information of the main distribution network.

[0073] By comparing the expected construction phase and status of the current main and distribution network with the actual construction phase and status of the current main and distribution network, the deviation of the engineering quantity is obtained.

[0074] The project time deviation is obtained by comparing the expected construction time of the current main and distribution network with the actual construction time of the current main and distribution network.

[0075] The deviation of project costs is obtained by comparing the expected construction costs of the current main and distribution network with the actual construction costs of the current main and distribution network.

[0076] The deviation of the main distribution network construction project is determined based on the deviation of the project quantity, the deviation of the project time, and the deviation of the project cost.

[0077] In this embodiment, actual construction information of the main distribution network is obtained through channels such as actual monitoring equipment and project management systems. This information includes actual construction time, actual cost, current project stage and status. The actual construction time, cost, project stage and status of the main distribution network are obtained from the actual information. Then, based on the established main distribution network construction project management model, the current actual situation is compared with the expected situation in the management model to obtain the deviation of the project quantity, the deviation of the project time and the deviation of the project cost. The obtained deviations of the project quantity, the deviation of the project time and the deviation of the project cost are comprehensively considered and determined by weight allocation or comprehensive calculation to determine the deviation of the main distribution network construction project. This allows for a more comprehensive assessment of the overall quality of the main distribution network construction project, helping decision-makers to adjust project plans and optimize resource allocation to improve the overall project quality.

[0078] In step S103 above, the assessment of the construction quality of each sub-project area using principal component analysis specifically includes:

[0079] Obtain several construction factors for each sub-project area, including construction personnel factors, construction equipment factors, construction laying factors, construction accident factors, and construction management factors;

[0080] Based on the covariance calculation formula, a covariance matrix is ​​constructed according to any two construction factors among all construction factors.

[0081] The covariance matrix is ​​decomposed to obtain several eigenvalues ​​and corresponding eigenvectors, and the eigenvalues ​​are sorted from largest to smallest.

[0082] The quality value of each construction factor is obtained by weighting and summing the eigenvectors corresponding to each of the first k eigenvalues ​​and the construction factors. The quality values ​​of each construction factor are then summed to obtain the quality value of each sub-project area.

[0083] By comparing the quality values ​​of each sub-project area, the quality ranking of the sub-project areas is obtained.

[0084] Specifically, the covariance calculation formula satisfies Wherein, cov(X) i ,X j X represents the covariance between any two construction factors. i and X j Let n represent any two construction factors out of all construction factors, and n represents the number of construction factors.

[0085] The covariance matrix satisfies

[0086] Where X1, X2, ..., X n For different construction factors.

[0087] In this embodiment, each sub-project area is investigated and analyzed to obtain several construction factors related to construction quality, such as the skill level of construction personnel, equipment condition, laying quality, accident rate, and management level. Based on the obtained construction factor data, the covariance between any two construction factors is calculated using the covariance calculation formula, constructing a covariance matrix. Then, the constructed covariance matrix is ​​decomposed into eigenvalues ​​to obtain several eigenvalues ​​and corresponding eigenvectors. The eigenvalues ​​are sorted from largest to smallest, and the eigenvectors corresponding to the top k eigenvalues ​​are selected. Each construction factor is weighted with these eigenvectors to obtain the quality value of each construction factor. The quality values ​​of each construction factor are summed to obtain the comprehensive quality value of each sub-project area. The comprehensive quality values ​​of each sub-project area are compared to obtain the quality ranking of the sub-project areas, enabling targeted management, improving the overall project quality, and providing project managers with decision support for different sub-project areas, helping them adjust resources and optimize management strategies. At the same time, through the comprehensive consideration of construction factors, the construction quality of each sub-project area is comprehensively evaluated, rather than just a single factor.
