Technical Field

[0001] The invention belongs to the field of fault detection, and in particular relates to a management system for power grid fault detection and power grid fault management. Background Art

[0002] The management system of power grid fault detection and power grid fault management is designed to solve the problems of fault detection and fault management in power systems. The power system is one of the most important infrastructures in modern society, but due to various reasons, such as equipment aging, natural disasters, human operational errors, etc., power grid failures occur from time to time. Once a failure occurs, it may cause power outages, equipment damage, or even safety accidents, which will have a serious impact on social production and life. Therefore, the development of an efficient power grid fault detection and management system is crucial to ensure the safe and stable operation of the power system.

[0003] Intelligent fault detection technology: With the development of technologies such as the Internet of Things, big data, and artificial intelligence, power grid fault detection technology has developed rapidly. Traditional fault detection mainly relies on manual inspections and equipment monitoring, which is inefficient and prone to omissions. The intelligent fault detection system based on the Internet of Things technology can monitor the operating status of power grid equipment in real time, and use big data analysis technology to deeply mine equipment operation data, so as to more accurately predict potential fault risks and realize timely detection of power grid faults.

[0004] Intelligent fault management technology: In terms of power grid fault management, traditional methods mainly rely on manual intervention, but with the development of intelligent technology, intelligent fault management technology has also developed rapidly. Using artificial intelligence, remote monitoring and other technical means, it is possible to quickly locate and diagnose power grid faults, assist operation and maintenance personnel to respond and handle them quickly, thereby shortening fault handling time, reducing power outage time, and improving the reliability and stability of the power grid.

[0005] Integrated management platform: With the continuous expansion and complexity of the power system, the demand for power grid fault detection and management is also growing. The integrated management platform can integrate fault detection, fault diagnosis, fault handling and other links to achieve full-process management and monitoring of power grid faults. Through the integrated management platform, it is possible to achieve real-time monitoring of the status of power grid equipment, rapid transmission of fault information, and intelligent decision-making for fault handling, thereby improving the efficiency and accuracy of power grid fault handling.

[0006] Therefore, the management system of power grid fault detection and power grid fault management is based on the combination of modern information technology and the needs of power system operation and management. It aims to improve the safety, reliability and stability of the power system and provide more scientific and intelligent technical service support for power grid operation and management. Summary of the invention

[0007] The present invention proposes a management system for power grid fault detection and power grid fault management, which solves the problems of fault detection and management in the power system, simulates the power grid scenario through an experimental platform, adjusts parameters in real time and feeds back data to ensure the stability and reliability of power grid operation.

[0008] The technical solution of the present invention is implemented as follows: a management system for power grid fault detection and power grid fault management, including a 380V management experimental platform and a 10KV fault experimental platform, wherein two main circuits are set in the 380V management experimental platform for power supply, the two main circuits are respectively connected to two fast switches, and the outlets of the two fast switches are respectively connected to user equipment, and the 10KV fault experimental platform is composed of two sections of independent busbars, each section of the busbar is not less than 5 circuits or more of the outgoing line circuit, the outgoing line circuit is composed of at least two levels of busbars, each outgoing line circuit is connected to different resistors and then grounded, and the resistance value of the grounding resistor is adjustable;

[0009] In the 380V governance experiment platform, the parameters are adjusted in real time through fast switches and adjustable reactors, and the 380V governance experiment platform is suppressed by generating overvoltage. The 380V governance experiment platform will feedback the change data in real time and display the real-time data in the operation interface;

[0010] The 10KV fault experiment platform is connected to the power grid, and switched between the power grid and the 380V governance experiment platform through a switching switch. When the fluctuation of the power grid exceeds the design threshold, the switching switch is connected to the 380V governance experiment platform. After adjusting the fluctuation parameters in the experimental fault platform, the adjusted data is transferred to the 380V governance experiment platform, and the fluctuation parameter data is rechecked on the two independent busbars in the 380V governance experiment platform. The fluctuation range is determined by comparing the re-checked data, and the source of the fault is pre-checked according to the fluctuation range, and the source of the fault is displayed through the operation interface after the table is organized.

[0011] Compared with the existing technology, the power grid fault detection and governance management system has the following differences: the traditional power grid fault detection system can usually only be simulated and tested in theoretical models or some actual scenarios, while the system provides a complete experimental platform, including a 380V governance experimental platform and a 10KV fault experimental platform. These experimental platforms can simulate the operation of the power grid more realistically, improving the credibility and effectiveness of the experiment. The system realizes real-time adjustment of parameters through equipment such as fast switches and adjustable reactors, and can generate overvoltage for suppression. Traditional systems usually require manual adjustment of parameters, which is inefficient and has a long response time. Real-time adjustment and feedback enable the system to respond more flexibly to various situations in power grid operation, improving the system's adaptability and resilience. When the system detects that the power grid fluctuation exceeds the design threshold, it can automatically switch to the 380V governance experimental platform for adjustment, determine the fluctuation range by rechecking the data, and pre-check possible fault sources. This pre-check function can help operation and maintenance personnel to promptly discover potential fault points and prepare countermeasures in advance, thereby reducing the impact of faults on the power grid.

[0012] By providing a complete experimental platform, the operation of the power grid can be simulated more realistically, making the experimental results more credible and providing a more accurate reference for power grid fault detection and management. The real-time adjustment and feedback functions enable the system to flexibly adjust parameters according to actual conditions, improve the system's adaptability to various power grid operation conditions, and ensure the stability and reliability of the power grid. The pre-check function can help operation and maintenance personnel discover possible fault points in advance and take timely measures to repair them, reducing the impact of faults on the power grid and ensuring the normal operation of the power system. The system improves the efficiency and accuracy of power grid fault detection and management through a complete experimental platform, real-time adjustment and feedback, and fault source pre-check functions, providing more scientific and intelligent technical support for power grid operation and management.

[0013] As a preferred implementation, the overvoltage amplitude, duration, grounding properties, fault line selection results and fast switch action time are displayed in the operation interface, and after obtaining the fault source sorting table, the data in the fault source table is arranged in descending order according to the matching degree.

[0014] As a preferred implementation, the grounding resistor provided in the 380V governance experimental platform adopts an adjustable grounding resistor, and the resistance value adjustment range is: 0 to 100 kilo-ohms.

[0015] As a preferred implementation, when the two independent busbars in the 380V governance experimental platform recheck the fluctuation parameter data, the adjusted fluctuation parameters are sent to the two independent busbars respectively, and the two independent busbars recheck them respectively, and after the recheck is completed, the fluctuation range of the fluctuation parameters is obtained by taking the average.

[0016] After adopting the above technical scheme, the beneficial effect of the present invention is: by real-time monitoring and adjusting the grid parameters, timely discovering potential fault risks and taking measures to deal with them, the impact of faults on the operation of the grid can be effectively reduced, and the safety and reliability of the grid can be improved. The system can quickly respond to grid fluctuations, pre-check possible fault sources, and provide accurate information for operation and maintenance personnel, which helps them quickly locate and solve faults, thereby shortening fault handling time, reducing power outage time, and improving the efficiency of fault handling. Through automated fault detection and governance, the dependence on manual intervention is reduced, the operation and maintenance costs and human resource investment are reduced, and the operation and maintenance efficiency is improved. The system provides a complete experimental platform and real-time data feedback function, which helps operation and maintenance personnel to understand the operation status of the grid more comprehensively, adjust parameters in time, optimize the grid operation management strategy, and improve the efficiency and stability of grid operation. By recording and analyzing fault data and processing processes, data support and reference can be provided for the continuous improvement of the power system, helping to optimize equipment configuration and operation management processes, and continuously improving the operation level and service quality of the power grid. The setting of the power grid fault detection and governance management system can effectively improve the safety, reliability and operation efficiency of the power grid, and provide important support for the stable operation and continuous improvement of the power system.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example:

[0021] like Figure 1As shown, a management system for power grid fault detection and power grid fault management includes a 380V management experimental platform and a 10KV fault experimental platform, wherein two main circuits are set in the 380V management experimental platform for power supply, the two main circuits are respectively connected to two fast switches, and the outlets of the two fast switches are respectively connected to user equipment, and the 10KV fault experimental platform is composed of two sections of independent busbars, each section of the busbar is not less than 5 outgoing line loops, the outgoing line loop is composed of at least two levels of busbars, each outgoing line loop is connected to different resistors and then grounded, and the resistance value of the grounding resistor is adjustable;

[0022] In the 380V governance experiment platform, the parameters are adjusted in real time through fast switches and adjustable reactors, and the 380V governance experiment platform is suppressed by generating overvoltage. The 380V governance experiment platform will feedback the change data in real time and display the real-time data in the operation interface;

[0023] The 10KV fault experiment platform is connected to the power grid, and switched between the power grid and the 380V governance experiment platform through a switching switch. When the fluctuation of the power grid exceeds the design threshold, the switching switch is connected to the 380V governance experiment platform. After adjusting the fluctuation parameters in the experimental fault platform, the adjusted data is transferred to the 380V governance experiment platform, and the fluctuation parameter data is rechecked on the two independent busbars in the 380V governance experiment platform. The fluctuation range is determined by comparing the re-checked data, and the source of the fault is pre-checked according to the fluctuation range, and the source of the fault is displayed through the operation interface after the table is organized.

[0024] This management system is designed to detect and manage power grid faults. It is divided into two parts: the 380V management test platform and the 10KV fault test platform. In the 380V management test platform, there are two main circuits for power supply, each of which is connected to a fast switch, and its outlet is connected to the user equipment. The parameters are adjusted in real time through the fast switch and adjustable reactor, and the platform is suppressed by generating overvoltage. The platform will feedback the change data in real time and display it in the operation interface. The 10KV fault test platform consists of two independent busbars, each of which includes at least 5 outgoing line loops, each of which consists of at least two busbars and connected to different adjustable grounding resistors. Next, the fault test platform is connected to the power grid and switched between the power grid and the 380V management test platform through a switching switch. When the power grid fluctuation exceeds the design threshold, the switching switch will be connected to the 380V management test platform. After adjusting the fluctuation parameters in the fault test platform, the adjustment data will be transmitted to the 380V management test platform. The two independent buses recheck the data, determine the fluctuation range, and pre-check the source of the fault. Finally, the sorted fault source table is displayed through the operation interface. This system can quickly detect and manage power grid faults through real-time monitoring, adjustment and feedback, thus improving the stability and reliability of the power grid.

[0025] In this management system, the 380V governance experiment platform and the 10KV fault experiment platform work together to provide a comprehensive solution for power grid fault detection and governance. Through real-time adjustment of fast switches, adjustable reactors and grounding resistors, the system can quickly respond to power grid fluctuations and perform corresponding suppression and adjustments. At the same time, through the display and organization of the operation interface, users can easily obtain real-time data and fault source information, which facilitates the diagnosis and handling of faults.

[0026] The entire workflow can be divided into three stages: real-time monitoring, fault response, and data collation. First, the system monitors grid fluctuations and parameter changes in real time. Once an abnormality is detected, it will respond immediately and make adjustments. Secondly, the system suppresses and governs the grid according to the adjustment parameters of the experimental platform. Finally, the system determines the source of the fault and the fluctuation range by comparing and collating the data, and displays and summarizes them. This complete set of processes enables the system to efficiently detect and govern grid faults, improving the reliability and stability of the grid.

[0027] This management system achieves rapid detection and management of power grid faults through the cooperation of the experimental platform and parameter adjustment. It also provides users with clear fault information through the display and organization of the operation interface, providing important support for power grid operation and management.

[0028] The operation interface displays the overvoltage amplitude, duration, grounding properties, fault line selection results and fast switch action time, and after obtaining the fault source sorting table, the data in the fault source table is arranged in descending order according to the matching degree. This management system has several significant differences and advantages in power grid fault detection and management. First, the system uses experimental platforms with rapid response capabilities, such as 380V management experimental platforms and 10KV fault experimental platforms, and realizes real-time adjustment and control of power grid parameters through fast switches, adjustable reactors and other equipment. This real-time response capability far exceeds that of traditional systems, allowing rapid response when power grid fluctuations or anomalies occur, thereby ensuring the stability and safety of the power grid.

[0029] The design of the operation interface is more intuitive and user-friendly, and can clearly display important parameters such as overvoltage amplitude, duration, grounding properties, fault line selection results, and fast switch action time. In addition, for the sorting table of fault sources, the system also arranges the data in descending order by matching degree, so that users can locate and solve power grid faults more quickly. This interface design and data sorting method greatly improves the user's operating efficiency and the accuracy of fault diagnosis. The main purpose of this setting is to improve the practicality and operating efficiency of the system. Through the intuitive and clear operation interface, users can quickly obtain key parameters and fault information, so as to diagnose and handle faults more efficiently. At the same time, the descending order of fault sources also allows users to prioritize the most likely faults, saving time and labor costs. This system setting has obvious advantages in real-time monitoring, data display and fault diagnosis, can more effectively deal with power grid faults, improve the operating efficiency and reliability of the power grid, and meet the needs of modern power systems for intelligent and efficient management.

[0030] The grounding resistor set in the 380V governance experimental platform adopts an adjustable grounding resistor, and the resistance value adjustment range is: 0 to 100 kilo-ohms. Traditional grounding resistors are usually fixed values ​​and cannot be adjusted. However, the grounding resistor of this experimental platform adopts an adjustable design, and its resistance value can be adjusted within the range of 0 to 100 kilo-ohms. The highlight of this design is its flexibility and adjustability. Traditional fixed grounding resistors can only work under specific conditions, while adjustable grounding resistors can be flexibly adjusted according to actual needs to adapt to different working conditions of electrical systems.

[0031] This adjustable grounding resistance setting has several significant functions and advantages. It provides greater flexibility and adaptability to meet the grounding needs in different scenarios. By adjusting the resistance value, the connection quality between the grounding resistor and the ground can be effectively controlled, thereby ensuring the safety and stability of the electrical system. Secondly, the setting of adjustable grounding resistance can help with experiments and research. During the experiment, it may be necessary to simulate the behavior of the electrical system under different grounding conditions, and the adjustable grounding resistance facilitates this need. In addition, by adjusting the value of the grounding resistance, system performance testing and optimization can also be performed, thereby improving the efficiency and reliability of the electrical system.

[0032] The application of adjustable grounding resistance in the design of 380V governance experimental platform is to improve the flexibility, adaptability and practicality of the system. Such a design can better meet the grounding requirements of electrical systems under different working conditions, and also provide more possibilities and convenience for experiments and research. Therefore, the setting of adjustable grounding resistance plays an important role in improving the performance and safety of electrical systems.

[0033] When the two independent buses in the 380V governance experimental platform recheck the fluctuation parameter data, the adjusted fluctuation parameters are sent to the two independent buses respectively, and the two independent buses recheck them respectively, and after the recheck is completed, the fluctuation range of the fluctuation parameters is obtained by taking the average. The traditional method is usually to send the fluctuation parameters through a single bus for detection, and then determine the fluctuation range of the fluctuation parameters based on the single detection results. However, this experimental platform adopts the method of sending the adjusted fluctuation parameters from two independent buses respectively, and obtaining the fluctuation range of the fluctuation parameters by taking the average. The highlight of this design is that it is more accurate and reliable.

[0034] This method has several significant effects and advantages. By sending the fluctuation parameters through two independent buses and taking the average, the measurement error that may exist in a single bus can be better avoided, and the accuracy and reliability of the fluctuation parameter data can be improved. The use of two independent buses for re-inspection can better verify the consistency and stability of the fluctuation parameter data, thereby improving the credibility of the test results. By taking the average to obtain the fluctuation range of the fluctuation parameters, the fluctuation parameter data sent by different buses can be more comprehensively considered, reducing the errors and deviations caused by a single measurement data.

[0035] The method of using two independent buses to send fluctuation parameters respectively and obtaining the fluctuation range of the fluctuation parameters by taking the average is to improve the accuracy and reliability of the fluctuation parameter data. Such a design can better avoid measurement errors, verify data consistency, reduce errors and deviations, and thus improve the credibility of the fluctuation parameter data. Therefore, this setting plays an important role in improving the measurement accuracy and reliability of fluctuation parameter data.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
