Research On The Application Of Hybrid Simulation Training Substation

Electricity is the main power source for national production.For power grid companies,the quality and reliability of power supply are continuously improved to ensure the economic efficiency and safety of production.With the growing scale of power grids and the increasing complexity of technology,the requirements for professional skills of power grid employees are also increasing.The direct response in substations is becoming more and more automated,and the amount of information is getting larger and larger.This requires substation operation,follow-up maintenance automation operation and maintenance technicians to keep pace with the times,and constantly improve the technical level through training and learning,and make a good equipment setting.Inspection and maintenance work to ensure the safety and stability of the power grid.However,in the existing three basic substation simulation training systems,the physical simulation system has a high construction cost,and it is not easy to expand and upgrade.The digital simulation system is not intuitive enough,requiring the operator to have a certain computer basis,and it is difficult to develop.Therefore,the development and improvement of the digital-physical hybrid simulation system is more in line with the actual production training needs.In this context,this article is entitled "Application Study of Hybrid Simulation Training Substation",and it is planned to further study the mechanism and application of hybrid simulation training substation.Through studying the overall scheme design of the hybrid simulation training substation,the overall structure and functional requirements of the system are clarified.At the same time,the technical support required for constructing the high-level mixed-imitation substation is clearly established.The key technologies are analyzed and analyzed to determine the solution and ensure the system construction.The feasibility of the final implementation of the hybrid construction simulation substation system construction in conjunction with the actual construction project,requires that the above system structural design content be followed,according to the specific substation functional requirements,to solve the main technical points,and to simulate and test the practicality of the design program and effectiveness.First,the overall architecture of the hybrid simulation training substation that is commonly used at present is introduced,including the coordination work principle and overall function implementation of each part of the substation,and then the hardware system and the software system configuration are further elaborated and elaborated.Technical support forresearch.Through the above-mentioned work,it is possible to have a macro-framework understanding of the hybrid simulation training substation,and at the same time clarify the research direction based on technical support.Then,based on the key technical support mentioned above,we will focus on further theoretical research on the primary system modeling based on real-time digital simulation technology,and adopt a more comprehensive and highly precise electromechanical-electromagnetic transient hybrid simulation algorithm.The electromagnetic transient simulation model and the electromechanical transient simulation model were established.The corresponding solving methods of the two types of simulation models were analyzed,and the data interaction principles on both sides of the electromagnetic and electromechanical were briefly analyzed.Finally,using the Huizhou Longyuan Training Base as an application pilot,the theoretical research of the above-mentioned hybrid simulation model was applied to the construction project of the hybrid simulation training substation of the base.The project is aimed at the current training of professional transformers to take theoretical study and on-site training.The status of training with long learning and training time,lack of systematicness and continuity,and poor training results.It is planned to develop and construct a digital and physical hybrid simulation training system covering 500 kV substations and 220 kV substations.According to the project requirements and in combination with the above theoretical points,this study completed the simulation of a system modeling of the Longyuan training base,and after corresponding completion of the secondary equipment configuration work,the simulated function test of the hybrid imitation substation training system was performed.Focusing on the simulation results of grid fault simulation,the simulation results show that the mixed imitation training system built according to the actual conditions of the training base in Huizhou Longyuan can accurately simulate various types of operations or faults,and the main technical difficulties are basically solved and can meet the needs of substations.The training needs of operation and maintenance automation operation and maintenance technicians.
