[0002] Automatic control software such as automatic generation control and automatic voltage control is a core component of the power dispatching automation system, and plays an important role in improving power quality and ensuring power grid safety. In recent years, there have been many abnormal control incidents in power grid automatic control software at home and abroad due to abnormal operator input and program deployment errors by operation and maintenance personnel. Therefore, it is urgent to improve the skills of power grid automatic control business practitioners and strengthen the risk prevention and control level of automatic control software.

[0003] Personnel qualification certification methods are targeted at a wide range of fields, but there is no method specifically for the qualification certification of power grid automatic control business personnel. At present, the competency examination for power grid automatic control practitioners is mainly a written test with fill-in-the-blank questions and answers. It cannot simulate various operating conditions of automatic control software, nor can it test the ability of practitioners to handle faults and anomalies. It lacks the practical operation ability of digital system automatic detection business personnel.

[0004] In addition, for practical exams, there is a lack of a method for generating a complete qualification certification case library that comprehensively considers business types and personnel types, as well as an automated, time-sequenced, and logical triggering mechanism for cases.

[0023] Glossary: AGC (Automatic Generation Control); AVC (Automatic Voltage Control); BDI agent, agent belief-desire-intention (BDI) model.

[0024] Example 1 The new power system places higher requirements on automatic control software, and software quality issues will seriously affect the safe and stable operation of the power grid. The existing power grid automatic control business personnel qualification certification examination cannot fully simulate the actual operation of automatic control software and evaluate the ability of practitioners to deal with faults and abnormalities.

[0025] like Figure 1 As shown, a digital qualification certification method for power grid automatic control practitioners includes: S1.

[0026] The digital qualification certification method provided by the present invention realizes comprehensive qualification certification of power grid automatic control practitioners through digital means, improves the objectivity and accuracy of certification, and promotes the skill improvement and career development of practitioners.

[0027] In an optional embodiment, the present solution further provides a digital qualification certification method for power grid automatic control practitioners, comprising the following specific steps: S100, determining the type of practitioners to be certified and the corresponding automatic control software type; In step S100, the qualification authentication environment includes a qualification authentication hardware environment and a qualification authentication software environment; The hardware environment for qualification certification includes: general examination templates and special examination templates; among them, the special examination templates correspond to the specific business direction of practitioners; The qualification certification software environment is built as follows: Based on the virtualized container image method, a modular container image of the qualification certification examination main program is created on the cloud platform virtual cluster host; wherein, the qualification certification examination main program includes a business subroutine and a business simulation task submission listening service; the business subroutine is used to simulate and implement the automatic control software function, and generate simulation events during the examination process; the business simulation task submission listening service is used to process the simulation events occurring during the examination process, and forward the simulation interaction data between the business subroutine and the practitioners, so as to realize the decoupling of the business subroutine and the practitioners' operations; based on the modular container image, and the basic power grid model data and power grid control model data required by the automatic control software, an examination environment template library is constructed for different automatic control software.

[0028] Optionally, the general examination is mainly used to evaluate the mastery of basic platform functions by power grid automatic control practitioners, which are the basic knowledge and skills that all relevant practitioners need to have when performing daily work. For the general examination template, it is necessary to configure a relational database server, a basic platform server, and a workstation, etc.; among which, the basic platform server includes various functional components of the basic platform.

[0029] Optionally, the special exam conducts an in-depth assessment of specific business directions in the field of power grid automatic control, such as AGC (automatic generation control) and AVC (automatic voltage control). For the special exam template, it is necessary to configure the relational database server, basic platform server, special application server and workstation, etc. Among them, the relational database server is pre-installed with the models required for the relevant special exams, the basic platform server is deployed with various functional components of the basic platform, the special application server is deployed with the application to be tested, such as AGC and AVC software, and the workstation is deployed with power system simulation tools and plant simulation tools.

[0030] Optionally, the qualification certification software environment is built based on virtualization container technology (such as Docker).

[0031] S200, based on the type of practitioners and the type of automatic control software, generating corresponding qualification certification examination cases in a pre-set qualification certification environment; In step 200, the qualification certification examination cases include application foundation qualification certification cases and application software qualification certification cases; the application foundation qualification certification cases include basic software and basic platform operation cases; the application software qualification certification cases include control software functions and event simulation.

[0032] S300, obtaining operation-related data of practitioners under the qualification certification test case, triggering the qualification certification test case based on the operation-related data, and determining the operation result of the automatic control software corresponding to the qualification certification test case triggering; In step S300, the qualification certification test case is triggered in the following manner: Obtain the operation-related data of practitioners and determine the operation status of the power grid under the operation-related data; based on the belief-desire-intention BDI agent model, define each simulation event type and set trigger conditions for each simulation event type under the current qualification certification test case; determine the trigger result of the simulation event type based on the operation-related data, the power grid operation status and the trigger conditions; wherein the belief-desire-intention BDI agent model includes a perception parser, a decision analyzer and an effect feedback device; the perception parser is used to obtain the operation-related data of practitioners and the operation status of the power grid under the operation-related data; the decision analyzer includes a belief layer, a desire layer and an intention layer; the belief layer stores the operation-related data of practitioners and the operation status of the power grid under the operation-related data; the desire layer is used to construct a specific simulation scenario based on the agent's desire; the intention layer is used to trigger the simulation event type based on the data stored in the belief layer and the simulation scenario constructed by the desire layer.

[0033] Optionally, this solution implements case event injection triggering based on BDI agent.

[0034] The perceptual parser serves as the input interface of the intelligent agent, which is used to receive various forms of information from the user (such as voice, text, etc.) and parse this information to convert it into a form that the intelligent agent can understand.

[0035] The effect feedback device serves as the output interface of the intelligent agent and is used to feed back the decision results or behaviors of the intelligent agent to the user in a way that the user can understand.

[0036] The decision analyzer is the core of the BDI agent, including beliefs, desires and intentions. Figure 3 Among them: Belief is the agent's understanding and knowledge of the environment, including the state of the power grid, the state of the equipment, and the state of communication. As the basis for decision-making, belief is stored in state cognition and provides the agent with the information needed for decision-making. Desire is the goal and motivation of the agent, such as changing the operation mode of the power grid, adjusting the state of the equipment, or executing dispatch commands. The desire layer converts the agent's goals into specific simulation scenarios and strategies, and predicts and evaluates the effects of different decisions through simulation. Intention is an action plan formed based on belief and desire. The intention layer converts desire into specific action instructions, such as triggering switching operations, handling equipment failures, or responding to dispatch commands.

[0037] The belief layer corresponds to the grid state, equipment state and communication state of the qualification authentication element layer, and the simulation implementation layer corresponds to state cognition, which stores all relevant information and data about the grid, which can be used to support the decision-making process of the intelligent agent. The desire layer corresponds to the change of grid operation mode, equipment shutdown / commissioning (equipment state change) and dispatching order of the qualification authentication element layer, and the state that the system hopes to achieve. These wishes of the intelligent agent can be converted into specific simulation scenarios and strategies, and the performance of the grid under different operations and decisions can be predicted through simulation, as well as the effect of these operations and decisions on realizing the wishes of the intelligent agent. The intention layer is an action plan formed based on its beliefs and wishes, corresponding to the simulation events such as the switching operation event trigger, equipment failure event trigger and dispatching order trigger of the qualification authentication element layer. Through the BDI intelligent agent model, the case simulation events are automatically and logically triggered.

[0038] S400: Based on the practitioners' operation-related data and the automatic control software running results, a comprehensive assessment is conducted on the practitioners to obtain the practitioners' skill assessment results and skill portraits.

[0039] Step S400 specifically includes: extracting the operation-related data and feature data from the automatic control software operation results; wherein the feature data is feature data that can affect the evaluation of qualification certification results; comparing the extracted feature data with the standard answers to the qualification certification test cases to obtain the answer comparison results of practitioners; conducting a comprehensive evaluation of the candidates based on the answer comparison results and a pre-established evaluation index system and evaluation rules to obtain a skill evaluation and skill portrait of the practitioners.

[0040] In order to further explain and illustrate the scheme of the present invention, in an optional embodiment, the present invention also proposes a digital qualification certification method for power grid automatic control practitioners, which realizes rapid deployment of the examination environment, automatic generation of examination cases and accurate assessment of candidates' skills through a qualification certification examination environment construction method for power grid automatic control business processes, examination case generation based on knowledge reasoning technology and intelligent agent technology, event automatic triggering method and unstructured operation analysis and evaluation method.

[0041] Specifically, the present invention provides a digital qualification certification method and system for power grid automatic control practitioners. The system builds hardware and software environments through templates, supports rapid customization and generation of diverse test cases, can automatically trigger case events and intelligently evaluate students' skill levels, and generate skill portraits.

[0042] like Figure 2 As shown, the method comprises the following steps: 1. Build a qualification certification environment.

[0043] Specifically, in this solution, the qualification certification environment includes the qualification certification hardware environment and the qualification certification software environment.

[0044] (1) The hardware environment for qualification certification includes the following: It should be noted that the field of automatic control software presents a diverse ecology, covering various types such as AGC and AVC. Different automatic control software manufacturers have designed different control strategies, operation interfaces and usage methods based on their own R&D concepts and proprietary technologies, resulting in significant differences in function implementation and user interaction between different software. Therefore, in this solution, different hardware solutions need to be configured for various types of qualification certification services, and various environmental templates are formulated in advance. Each type of template provides multiple sets of solutions based on the number of manufacturer versions.

[0045] 1) General exam template The general examination refers to the basic platform functions that power grid automatic control practitioners should master. Each general examination qualification certification environment should be equipped with a relational database server, a basic platform server (including various functional components of the basic platform) and a workstation.

[0046] 2) Special exam template Special examinations refer to targeted examinations taken by power grid automatic control practitioners for their own business. For example, AGC practitioners only need to take the AGC application software practical certification examination, and AVC practitioners only need to take the AVC application software practical certification examination.

[0047] Each special examination qualification certification environment should be equipped with a relational database server (with the models required for the relevant special examinations downloaded in advance), a basic platform server (to deploy the various functional components of the basic platform), a special application server (to deploy the applications to be tested, such as AGC and AVC software) and a workstation (to deploy power system simulation tools and plant simulation tools).

[0048] (2) Establishment of qualification certification software environment; Specifically, based on the business characteristics of AGC and AVC and the business responsibilities of engineering implementation personnel and operation and maintenance personnel, a variety of examination environment templates are constructed to form a qualification certification examination environment template library, which serves as the basic environment for conducting qualification certification examinations.

[0049] like Figure 3 As shown in the figure, this solution builds the certification exam software environment based on virtualized container image technology.

[0050] Specifically, a virtualized container image is a lightweight, portable software package that contains everything needed to run an application (code, runtime, libraries, environment variables, and configuration files). Users can run applications in the same way in any environment, thus avoiding the problem of only being able to run on dedicated machines.

[0051] This solution is based on containerization technology to design, orchestrate and configure the qualification certification examination environment, and uses container technologies such as Docker to create and manage modular container images on cloud platform virtual cluster hosts.

[0052] Among them, the qualification certification examination main program includes business subroutines and business simulation task submission monitoring services. The construction of business subroutines includes business simulation software bodies such as AGC and AVC, which can simulate and realize the functions of automatic control software. Its program dependency library includes the dependencies required by business subroutines and operating system dependencies such as Linux. The business simulation task submission monitoring service can handle simulation events that occur during the examination and forward simulation interaction data, realize the decoupling of business subroutines and personnel operations, and improve the overall flexibility of the system.

[0053] After the container image is established, a test environment template library is built for different automatic control software. The template library includes modular container images and the basic power grid model data and power grid control model data required by the automatic control software. The template library management module is used to implement the full life cycle management of the test environment template library, including creation, online, update, label management, version management, and offline management. When deploying the qualification certification test environment, the test environment template is selected and quickly loaded according to the type of candidate. The cloud platform virtualization cluster is used to divide virtual computing resources and automate and distribute case images. During multiple rounds of examinations, virtualization technology is used to achieve rapid recovery of basic software, basic platforms, and applications, and to achieve "on-demand construction and one-click deployment" of the qualification certification test software environment.

[0054] 2. Generation of qualification certification examination cases.

[0055] Specifically, when the qualification certification examination is actually implemented, corresponding qualification certification examination cases are generated according to the type of automatic control software and the type of practitioners. In this scheme, two types of qualification certification examination cases are included: application foundation type and application software type.

[0056] During the engineering implementation and operation and maintenance of automatic control software, the work content of professionals is closely related to the functions of the basic platform, and the basic platform is the key support for the successful execution of tasks by automatic control software.

[0057] Basic application cases include basic software and basic platform operation cases; basic software operation cases include basic platform functions such as message bus, service bus, system management, log management and permission management, and platform operation event simulation. The qualification certification of engineering implementation and operation and maintenance personnel needs to examine their mastery of the basic platform functions; basic software cases include routine operations and exception handling of operating systems and relational databases; basic platform cases include routine operations and exception handling of basic services at the platform layer of power dispatching automation systems (D5000 systems and new generation systems).

[0058] Application software cases include control software functions such as AGC and AVC, and event simulation. The cases must include power grid models, continuous operation data, AGC / AVC control models, and simulation events.

[0059] As an example, the power grid model includes a variety of power equipment such as transformers, transmission lines, loads, busbars, circuit breakers, capacitors, reactors, energy storage equipment, renewable energy equipment, and protection and automation equipment. The electrical characteristics and parameters of these devices are used to accurately simulate the operation status and performance of the power grid. Continuous operation data is based on historical data uniformly stored in the center, and continuous operation data is generated by interpolation using power system simulation tools. The AGC / AVC control model is obtained from the actual system or the corresponding control strategy is established according to the standard model, and the control parameters and control mode can be modified. The initial construction of model data (including basic power grid model, control model and operation data) can uniformly adopt the actual power grid model data of a certain province. In the later stage, in order to ensure the fairness of the examination, the standard model data formulated by the qualification certification center is adopted. The standard model data can be generated according to the actual power grid operation model data through model splicing, model clipping, model equivalence, data proportional adjustment and other methods. Simulation events include load disturbance, interconnection line power fluctuation and other data fluctuations and calculation functions, RTU (remote terminal unit) data dead number, jump, AGC exit and other abnormal and fault conditions simulation, inspecting personnel's system routine business operation and fault abnormality handling capabilities.

[0060] The specific simulation events are shown in Table 1.

[0061] Table 1 Simulation events for the automatic control practitioners qualification certification case

[0062] 3. Case event injection trigger; like Figure 4 As shown in the figure, a BDI agent case event injection structural model is constructed; among them, the perception parser and the effect feedback are the interaction modules between the agent and the external environment. The perception parser receives the user's needs in various forms such as voice and text, and the effect feedback refers to the behavior trigger, which feeds back information or behavior to the user; the decision analyzer is the main body of the BDI agent, and the belief is the agent's understanding and cognition of the environmental state, corresponding to the operating state of the power grid, control software and other systems; the desire is the agent's planned goal and motivation, which is composed of the information base, including database, experience base, rule base, etc.; the intention is the planning and decision-making of the demand using its own beliefs and desires.

[0063] The relationship between the elements of each layer of the BDI model and the qualification certification system is as follows: Figure 5As shown. The BDI concept layer includes beliefs, wishes and intentions. The belief layer corresponds to the grid state, equipment state and communication state of the qualification authentication element layer, and corresponds to state cognition in the simulation implementation layer. It stores all relevant information and data about the grid, which can be used to support the decision-making process of the intelligent agent. The wish layer corresponds to the change of grid operation mode, equipment shutdown / commissioning (equipment state change) and dispatching order of the qualification authentication element layer. These wishes of the intelligent agent can be converted into specific simulation scenarios and strategies. Through simulation, the performance of the grid under different operations and decisions can be predicted, and the effect of these operations and decisions on realizing the wishes of the intelligent agent can be evaluated. The intention layer is an action plan formed based on its beliefs and wishes, corresponding to the simulation events such as the switching operation event trigger, equipment failure event trigger and dispatching order trigger of the qualification authentication element layer. Through the BDI intelligent agent model, the automatic and logical triggering of case simulation events is realized.

[0064] 4. Intelligent assessment generates student skill profiles.

[0065] like Figure 6 As shown, in order to solve the problems of diversity of examination cases and examination process operations, and heavy workload of manual scoring, an intelligent evaluation system is built, and an intelligent evaluation method for qualification certification examinations for automatic control business practitioners is proposed.

[0066] First, we process the data of various processes, such as the operations of candidates and the results of software operation during the examination. Through the standardized collection and analysis of multimodal data during the qualification certification examination, we transform the personnel's answering process and results into structured data such as simulated operation sequence and knowledge assessment for different forms of practical examinations and paper answers, and realize the automatic transformation of unstructured operations into structured records.

[0067] Then, feature extraction is performed. A training and exercise record rule matching model and a knowledge and skills information rule matching model can be constructed to automatically compare standardized records with standard answers to qualification certification exam cases by extracting key process data that affects the evaluation of qualification certification results. For records that the system cannot automatically identify, model optimization is performed based on expert experience.

[0068] Finally, considering the basic software implementation and operation and maintenance skills, application business operation skills, software anomaly and fault handling skills, a comprehensive evaluation index system and evaluation rules are established from the perspectives of the speed, correctness, and standardization of the test operation, including operation accuracy, power grid safety, operation standardization, knowledge proficiency, fault handling effectiveness, and operation speed.
