[0051] Embodiment 1

[0052] like Figure 1 As shown, this embodiment provides a method for evaluating the collaborative contribution of business expansion and power connection engineering projects. This embodiment uses the method applied to a server as an example. It can be understood that the method can also be applied to a terminal, and can also be applied to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. The server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network servers, cloud communications, middleware services, domain name services, security services CDN, and big data and artificial intelligence platforms. The terminal can be a smart phone, a tablet computer, a laptop computer, a desktop computer, a smart speaker, a smart watch, etc., but is not limited to this. The terminal and the server can be directly or indirectly connected via wired or wireless communication, which is not limited in this application. In this embodiment, the method includes the following steps:

[0053] According to the business expansion and power connection project to be evaluated, obtain project data, engineering data and electrical equipment data;

[0054] Based on project data, engineering data and electrical equipment data, calculate relevant indicators, including: project power connection capacity level, project distribution network operation balance level, electrical equipment comprehensive load level, project engineering quantity, project time limit compliance and customer satisfaction;

[0055] Based on the project power connection capacity level, project distribution network operation balance level, electrical equipment comprehensive load level, project engineering volume, project time limit compliance and customer satisfaction, combined with the weights of the set relevant indicators, the weighted sum is calculated to obtain the collaborative contribution of the business expansion and power connection project, which is used to locate weak projects.

[0056] The present embodiment is described in detail below:

[0057] First, determine the indicator framework for project collaborative quality and efficiency evaluation.

[0058] The synergy quality and efficiency of the business expansion and power connection project reflects the quality of the project power connection service, and reflects the overall work service contribution of different projects to the company's high-quality completion of the business expansion and power connection project implementation and meeting the customer's power demand. The evaluation indicator framework includes project implementation benefits, project implementation complexity, project time limit compliance, and project customer satisfaction.

[0059] Secondly, quantitatively analyze the project collaborative contribution indicators.

[0060] 1. Project implementation benefits mainly include the project power connection capacity level and the project distribution network operation balance level.

[0061] (1) The power connection capacity is the overall capacity level of the project after all power connection works are completed and the customer's power facilities are connected to the grid. 10kV, 35kV, and 110kV projects are divided according to voltage levels, and new installation and capacity expansion projects are determined according to project acceptance types: single-post and non-single-post projects are determined according to project power type, and single power and dual power projects are further distinguished. The project power connection capacity level is:

[0062] C pj =C pd / C pt / C at / C vl

[0063] Among them, C pj is the project connection capacity level, C pd The capacity reported for the project, C pt is the power type capacity of the project, C at is the project acceptance type capacity, C vl It is the voltage level capacity of the project.

[0064] The calculation formula for project capacity is as follows:

[0065] For low voltage users, E i C iee is the capacity of the i-th device.

[0066] For users above T i P ta It is the sum of the nominal apparent powers of the receiving transformers connected to the power system.

[0067] (2) The project distribution network operation balance level indicates the impact of the project capacity access on the distribution network operation stability. It is measured by the project capacity to the total distribution network capacity margin. The higher the proportion, the better the project distribution network operation balance level (cannot exceed the total distribution network capacity). The project distribution network operation balance level is:

[0068] L pb =C pd / C tdn

[0069] Among them, L pb is the project distribution network operation balance level, C pd For project power connection and installation capacity, C tdn It is the total capacity of the distribution network in the substation area.

[0070] Specifically, the total capacity of the distribution network in the substation is based on the rated capacity and load rate of the main transformer of the distribution network in the substation. The load rate refers to the ratio of the actual load of the transformer to the rated capacity, which is generally about 80%. For example, a 1000kVA distribution transformer can supply 800kVA of capacity at a load rate of 80%. Therefore, the total capacity of the distribution network in the substation can be calculated according to 800kVA. Therefore, the total capacity of the distribution network in the substation = 80% * rated capacity of the main transformer.

[0071] 2. Project implementation complexity

[0072] The complexity of project implementation is mainly calculated based on the comprehensive load level of electrical equipment and the project engineering volume. The comprehensive load level of electrical equipment is calculated based on the type and power of the customer's electrical equipment. The comprehensive load level of electrical equipment is:

[0073]

[0074] Among them, L cl is the comprehensive load level of electrical equipment, is the maximum power sum of all electrical equipment, P drs is the probability of each device running simultaneously, is the sum of the power factors of each device, L dnm It is the maximum load of the distribution network.

[0075] The project volume is:

[0076] Q p =L c / M c

[0077] Among them, Q p is the project volume, L c is the cable length, M c It is the overall construction mileage of the project.

[0078] 3. Project time limit achievement

[0079] C pt =(TLAR ba +TLAR sr +TLAR pc +TLAR dr +TLAR ii +TLAR ca +TLAR cp ) / 7

[0080] Among them, TLAR ba TLAR is the time limit compliance rate of business acceptance link sr TLAR is the time limit achievement rate of the power supply plan response phase pcTLAR is the time limit achievement rate of supporting engineering links. dr TLAR is the time limit achievement rate of the facility review phase ii TLAR is the time limit achievement rate of the intermediate inspection link ca TLAR is the time limit compliance rate of the completion acceptance phase. cp It is the time limit compliance rate for meter installation and power connection.

[0081] Among them, the time limit achievement rate of each link = the achievement rate of each link * the proportion of link duration.

[0082] 4. Customer Satisfaction

[0083] Customer satisfaction is the overall level of customer satisfaction with the project power connection service, which is based on the customer's complaint rate and satisfaction evaluation, and is based on the customer's telephone interview records. Customer satisfaction is:

[0084] S c =T cs / T tv

[0085] Among them, S c For customer satisfaction, T cs is the number of visits to satisfied customers, T tv is the total number of visits.

[0086] Finally, determine the weight design of each indicator.

[0087] The analytic hierarchy process and Delphi method are used to design the weights of each indicator.

[0088] The first step is to establish a hierarchical model. The hierarchical model can divide complex problems into three levels according to the purpose of evaluation, namely the target level, the criterion level and the indicator level. Based on this, the synergy quality and efficiency indicator system of the power expansion project is divided into two levels. The first level is the target level, namely the synergy quality and efficiency of the power expansion project, and the second level is the criterion level, including four evaluation dimensions: project implementation benefits, project implementation difficulty, project time limit compliance, and project customer satisfaction.

[0089] The second step is to construct a judgment matrix. The judgment matrix of the hierarchical analysis method is shown in Table 1. In the construction matrix, experts in this field compare the importance of indicators in pairs based on theory and experience, and assign scores to them. The scores are based on the 1-9 scale proposed by Professor Sate, as shown in Table 2:

[0090] Table 1. Judgment matrix constructed by AHP

[0091]

[0092]

[0093] Table 2 Definition of Sate Standard

[0094]

[0095] The third step is hierarchical single sorting. Hierarchical single sorting refers to the process of calculating the relative importance weights of each factor at each level according to a certain calculation method and performing consistency checks. The weight calculation process is as follows (n is the order of the judgment matrix):

[0096] (1) Calculate the product M of each row element in the judgment matrix A i :

[0097]

[0098] (2) Calculate M i The nth root of

[0099]

[0100] (3) Vector After normalization, the result is the weight of each indicator factor:

[0101]

[0102] (4) Perform consistency check. In the above scoring process, there may be some contradictions due to human subjective influence, so the matrix needs to be checked for consistency. The steps are as follows:

[0103] 1) Calculate the maximum eigenvalue of the judgment matrix:

[0104]

[0105] 2) Calculate the consistency deviation index:

[0106]

[0107] 3) Calculate the random consistency ratio CR:

[0108]

[0109] If CR < 0.1, it means that the matrix meets the consistency test, where RI is the average random consistency index, which can be obtained by querying the average random consistency index table, as shown in Table 3:

[0110] Table 3 Average random consistency index

[0111] Degree 1 2 3 4 5 6 7 8 9 RI 0 0 0.52 0.89 1.12 1.26 1.36 1.41 1.46

[0112] Step 4: derive the calculation results. This embodiment uses Yaahp as an auxiliary software for the analytic hierarchy process (AHP), which can accurately and quickly calculate the weights of each indicator. Based on the existing expert scoring data, the judgment matrix is ​​constructed with the help of Yaahp software. The weights of each indicator derived by Yaahp are shown in Table 4:

[0113] Table 4 Weight distribution table of project expansion synergy quality and efficiency evaluation indicators

[0114]

[0115] Finally, based on the relevant indicators of project implementation benefits, project implementation difficulty, project time limit achievement and project customer satisfaction, combined with the set weights, the project business expansion and power connection synergy quality and efficiency value is calculated.

[0116] In order to illustrate the feasibility of the present invention, the data of business expansion and power connection in a certain city in September 2023 are selected. The project data, engineering data, and electrical equipment data are shown in Tables 5, 6, 7, 8, 9, and 10:

[0128] Table 10 Electrical equipment data

[0129]

[0130]

[0131] Carry out quantitative calculation of each indicator. Calculate the results of each indicator based on the extracted data.

[0132] (1) Project benefits.

[0133] Project power connection capacity level = project reported capacity / single-post project capacity / newly installed project capacity / 10kV project capacity = 0.00000011%.

[0134] Project distribution network operation balance level = project power connection capacity / total distribution network capacity in the substation = 48%

[0135] (2) Difficulty of project implementation.

[0136] The comprehensive load level of electrical equipment = the sum of the maximum power of all electrical equipment * the probability of simultaneous operation of each equipment * the sum of the power factors of all electrical equipment / the maximum load of the distribution network = 1.67

[0137] Project engineering quantity = project cable length / project overall construction mileage = 12.44%

[0138] (3) Project time limit compliance rate = average time limit compliance rate of all links = 13.38%

[0139] (4) Customer satisfaction = number of satisfied customers / total number of visits = 100%

[0140] Evaluate the synergistic contribution of each project. Calculate the synergistic quality and efficiency of the project business expansion and power connection according to the weight of each indicator = 0.00000011%*10%+48%*10%+1.67*10%+12.44%*10%+13.38%*30%+100%*30%=0.57

[0141] The project contributions are ranked based on the results, and the contribution degree of each project is ranked, so as to reward excellent projects and warn lagging projects.
