Description

Technical Field

[0001] The present invention relates to the field of electrical digital transformation assessment, and in particular to a maturity evaluation method for digitalization and transparency technology of a direct current transmission converter valve hall. Background Art

[0002] The new power system emphasizes the progress of digital technology and demand-driven changes. The academic and industrial communities attach great importance to the value of massive data in the power system and are actively exploring the application of new models and methods based on data drive in the power system. With the development of "digital new infrastructure", the amount of data and data value of the power system will be further improved, which will greatly promote the digitalization and transparency of DC transmission converter stations. The power transmission and transformation system will gradually become a high-level information-physical system with complex structure, numerous equipment and complex technology. The research on its related supporting technologies is also showing an explosive growth trend.

[0003] However, digitalization and transparency construction is a complex implementation process that requires the integration of multiple digital enabling technologies and achieving the best results in the operating environment. For example, the construction of ubiquitous Internet of Things, information extraction of multi-agent systems and other technologies emphasize key issues such as information acquisition, data quality, and simulation dimensions. However, due to the lack of evaluation and feedback on the maturity of digitalization and transparency technologies by power companies, it is easy to lead to unreasonable resource allocation and insufficient efficiency, making it difficult to fully and accurately grasp the application level and construction direction of digitalization and transparency.

[0004] In view of the current construction process of the new power system, a clear and targeted definition of the digitalization and transparency maturity of the valve hall is needed to classify its capability domains in order to evaluate its construction quality and efficiency. However, the existing digitalization and transparency maturity model of the power system has significant limitations in terms of technical rigor and dimensional relevance. On the one hand, it ignores the specific real-life scenario characteristics, relevant technical organizations, and the interaction between scenario characteristics and business needs. For example, the data interaction of the cyber-physical system is no longer limited to specific physical entities and technical architectures, but requires a more intelligent, interconnected and convenient communication chain; on the other hand, it is out of touch with the existing technical theories, only involves the evolutionary process of digital transformation, and lacks theoretical support for evaluation indicators. Summary of the invention

[0005] The purpose of the present invention is to overcome the limitations of the above-mentioned existing maturity models of digitalization and transparency of power systems and to provide a method for evaluating the maturity of digitalization and transparency technology of DC transmission converter valve halls, which can evaluate the maturity of the technology in an objective and comprehensive manner, help to accurately judge the development stage and potential risks of the technology, and provide strong support for the formulation of R&D and application strategies.

[0138] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0139] Example 1

[0140] Based on the current business needs and technical status of the DC transmission converter valve hall, the present invention combines the current digital transformation trends in various industries, domestic and international digital transformation standards, and digital transformation maturity levels and their ten detailed standards. From the five levels of specification level, scenario level, field level, platform level, and ecological level, the grading and classification method and evaluation criteria for the digitalization and transparency of the valve hall technology maturity are formulated around the five evaluation domains of development strategy, new capabilities, systematic solutions, governance system, and business innovation transformation. Combined with the technical standards for the national digital transformation maturity assessment, considering that the converter valve hall has extremely complex state characteristics, multiple targeted evaluation indicators are established for different application fields of the valve hall, and different standards and weights are set to establish a targeted maturity evaluation process. The specific evaluation plan is as follows:

[0141] Step 1: Based on the existing theoretical research and application practice on the digitization and transparency of the DC transmission converter valve hall, the present invention is divided into the following six levels according to the characteristic functions and uses of the digitized and transparent DC transmission converter valve hall:

[0142] 1) Highly integrate and organize the scattered and chaotic information in an orderly, structured and standardized manner for multi-dimensional and multi-business needs;

[0143] 2) Collaborative application of physical models of DC transmission converter valve hall buildings, equipment, etc.;

[0144] 3) Integration of multi-level information, models and resources;

[0145] 4) High-fidelity dynamic visualization hooking based on entity ordering and structured information organization;

[0146] 5) Panoramic and full-state resource optimization management and efficient interaction of DC transmission converter valve hall;

[0147] 6) Highly reliable platform tools and their friendly service paradigm.

[0148] In step 1, based on the characteristics of the converter valve hall in terms of "shape, machine, electricity, control, environment, and temperature" and the operation and maintenance requirements, the converter valve hall is digitized and transparent in five maturity levels from the four dimensions of information organization, correlation interaction, integration, and functional services, focusing on the technical requirements of sensor technology, modeling technology, perception technology, visualization technology, human-computer interaction technology, information mining methods, and software platforms. Each maturity level has different capabilities, such as Figure 1 The five maturity levels are:

[0149] Level 1 (L1): Information Description

[0150] Level 1 maturity refers to the use of information technology to describe and characterize the unilateral or multi-faceted attributes and characteristics of valve hall equipment entities from one or more dimensions of operating status, physical information, and operation and maintenance rules. However, the information model of the valve hall and the equipment entity cannot achieve real-time interaction through direct data exchange, and mainly rely on manual intervention to achieve indirect information organization and knowledge interaction, including control of equipment entities and optimization and updating of digital models.

[0151] Level 2 (L2): Multi-point mapping

[0152] Multi-point mapping refers to mapping the real-time status and change process of the valve hall based on time, space and environmental constraints. This level is driven by time-sensitive status and entity-related data, and to a certain extent breaks through the limitations of three-dimensional constraints on the organization of multi-source information in the valve hall. However, the operation and maintenance status analysis and key node reasoning of the valve hall operation and maintenance still rely on manual intervention. For example, the ability to obtain and organize information on the shielding structure inside the valve tower is limited, and transparent perception of the valve hall cannot be achieved.

[0153] Level 3 (L3): Dynamic Visibility

[0154] In the third level of maturity, a relatively complete informatization organization of digital models in the information space has been achieved, and relatively complex operation processes and related information transparency can be completed. At the same time, on the basis of information transparency, the data transmission channel from valve hall information to physical models is incrementally constructed to build a dynamic two-way closed-loop interaction, thereby realizing the orderly organization and visualization capabilities of multi-source information. For example, the coupled distribution of electrical, magnetic, and thermal fields inside the dynamic visualization valve tower and their interactive characteristics further break through the limitations of space and environmental constraints on the acquisition of equipment entity information.

[0155] Level 4 (L4): Time Analysis

[0156] Time-effectiveness analysis refers to the dynamic two-way closed-loop interaction from valve hall information to physical models, realizing the integration and connection of all information elements of the valve hall, dynamically reflecting the current actual status of the valve hall, and realizing the state association and knowledge traceability of the whole valve hall through the reasonable organization and integration of the explicit mechanisms and implicit laws described by multi-source operation and maintenance knowledge. By processing the knowledge elements of the whole valve hall, efficient knowledge acquisition, time-effectiveness analysis and transparent application of the valve hall status can be met. For example, information such as the operating status, technical parameters, physical structure and environmental auxiliary control of all elements of the valve hall can be constructed, and the unified valve hall operation characteristics described by multi-dimensional knowledge sources can be integrated to facilitate proactive maintenance in advance.

[0157] Level 5 (L5): Business Collaboration

[0158] At this level, the digitization and transparency of the valve hall can not only reflect the operating status in real time and reflect the operating trend in combination with timely operation and maintenance knowledge, but also realize the dynamic reconstruction and feature description of the valve hall model and knowledge based on the updated content of the two-way interactive real-time perception and cognition of the valve hall status, so that the two can maintain dynamic consistency during long-term operation. For example, the appearance shape, physical size, physical structure, technical parameters, operating status and other types of external features and content features of the shielding equipment in the valve hall are characterized and sorted, integrated, feature revealed, visualized and functionally served, and a service function subject covering the entire business is constructed, so that multi-source information sets can be effectively circulated, thereby ensuring the effectiveness of many functional services including visualization, prediction, decision-making, optimization, etc., and realizing visible, knowable and controllable full business collaboration.

[0159] Step 2: Further analyze the four dimensions of information organization, related interaction, integration and functional services to obtain 18 related indicators that can affect the maturity level of valve hall digitalization and transparency. Use them as evaluation indicators for fine-grained maturity division, and clarify the specific requirements of each maturity level for the maturity level of the evaluation indicator:

[0160] 2.1 Evaluation indicators of information organization dimension

[0161] The information organization dimension is responsible for perceiving the information and non-electrical information elements of the valve hall and providing basic information support. Therefore, the information organization dimension needs to be evaluated and graded in terms of maturity from five aspects: information perception capability, information coverage, information organization quality, information integration capability, and physical entity completeness of the valve hall model, as shown in Table 1.

[0166] Associative interaction is an important dimension that connects information infrastructure and business needs. The scope and quality of information's full-factor expression capabilities, collaborative capabilities, data transmission capabilities, and information interaction capabilities determine whether the valve hall can provide middleware support for digital and transparent construction and meet the dynamic, changeable and complex applications in the valve hall's operation and maintenance environment. The evaluation indicators are shown in Table 2.

[0169]

[0170] 2.3. Evaluation indicators of integration dimension

[0171] The digital and transparent construction of the valve hall requires the integration of technology, information and resources based on business needs and target functions, so as to open up the overall digital and transparent architecture, form an effective technical organization, decision-making support and rich business compatibility. Therefore, the maturity level of the integration capabilities in five aspects, namely function, demand, information, technology and resources, is graded, as shown in Table 3.

[0173]

[0174]

[0175] 2.4 Evaluation indicators of functional service dimensions

[0176] The application capability, application level, application integration and flexibility of functional services are the key to whether the valve hall information elements can be fully utilized and their value can be fully utilized. Based on the previous digitalization and transparency work, this paper divides the maturity level of the valve hall data, information and knowledge visualization level, information application level, tool platform collaboration capability and information service capability, as shown in Table 4.

[0177] Table 4 Evaluation indicators of functional service dimensions

[0178]

[0179] Step 3: The application process of the maturity assessment model is divided into three stages, such as Figure 2As shown. In the first stage, evaluation experts are invited to make preliminary weight setting and maturity scoring for each single evaluation indicator. Due to subjective judgment bias of evaluation experts, unreasonable weight and maturity scoring should be avoided. In the second stage, in order to improve the consistency of setting values, it is necessary to conduct consistency evaluation of weight setting and maturity scoring for each single indicator of the maturity model. In the process of maturity evaluation, preliminary single indicator weight setting and maturity scoring should be objectively carried out based on the current development results of digital transformation through statistics, evaluation, experiment, investigation and other forms. The purpose of preliminary single indicator weight setting and maturity scoring is to set the initial consideration benchmark for maturity evaluation, so as to comprehensively consider the actual digitalization and transparency construction degree of the valve hall in the subsequent maturity evaluation process. In addition, the maturity of the evaluation indicator can be calculated separately to reflect the digitalization and transparency capabilities of the valve hall in each dimension; it can also be weighted based on the single weight and score to obtain the overall digitalization and transparency capability maturity level of the valve hall.

[0180] In step 3, A is represented as a judgment matrix of the weight setting and maturity score of each single evaluation indicator, and different evaluation indicators and maturity are compared pairwise, and a judgment matrix is ​​constructed based on the hierarchical analysis method:

[0181]

[0182] Among them, a ij It represents the comparison of the importance of indicator i relative to indicator j. The purpose of judgment matrix A is to calculate the initial weight or the maximum characteristic root of the score vector. The consistency of the initial weight and score calculated based on judgment matrix A is:

[0183]

[0184] Among them, CI is the consistency between the initial weight and the score, n is the number of evaluation indicators, λ max is the maximum eigenvalue of matrix A. On this basis, the consistency expectation CR is calculated:

[0185]

[0186] Among them, RI is the consistency index, which is calculated as follows:

[0187]

[0188] Among them, λ avg It is the average value of all eigenvalues ​​in matrix A. In this paper, the consistency expectation threshold is set to 50%, that is, when CR < 0.5, the weight and score of the evaluation index are judged to have satisfactory consistency, otherwise the experts need to reset the weight and score of the evaluation index.

[0189] In the third stage, i.e. maturity calculation, the maturity score D of the single dimension is calculated based on the initial single indicator weights and maturity scores that meet the consistency expectations. n :

[0190]

[0191] Among them, m represents the number of single evaluation indicators under a single evaluation dimension; α i represents the weight of the i-th evaluation index, β i Represents the maturity score of the jth evaluation indicator. S represents the overall final score of the digitalization and transparency maturity of the valve hall. The final result should be composed of the maturity score of the single dimension and its total weight. Since this paper sets the evaluation indicators of four dimensions, therefore:

[0192]

[0193] Among them, 4 represents the four dimensions of maturity evaluation in this paper, and ε is the scoring ratio coefficient, which represents the total weight of the nth evaluation dimension. Based on the final maturity score, the digitalization and transparency maturity of the valve hall is divided into five levels, as shown in Table 5.
