[0001] This utility model belongs to the field of power system automation and intelligent monitoring technology, and in particular relates to a substation monitoring system based on topology. Background Technology

[0002] As the power grid expands, the number and complexity of substations are also increasing. Existing substations often contain various equipment, such as monitoring equipment, environmental monitoring equipment, and power monitoring equipment. Traditional monitoring and management methods rely on manual data recording and on-site inspections of each device, which cannot effectively obtain the operational status of each device or enable remote control and monitoring. Furthermore, data from each substation needs to be manually entered into the system, and then stored and processed by a physical server. This requires a powerful physical server, increasing costs. Moreover, if there is only one server, data loss is likely if the server fails. Therefore, traditional monitoring methods are insufficient to meet the needs of efficient, real-time, and accurate monitoring of a large number of substations.

[0003] With the continuous development of technologies such as big data and cloud computing, data processing and intelligent management have become important development directions for the power industry. Therefore, this utility model provides a substation monitoring system based on a topology structure. Summary of the Invention

[0024] Among them, cloud servers are used to provide functions such as data storage and data computing, and can work with data servers to achieve comprehensive management of device-level data.

[0025] The primary communication protocol for the Internet is the IEC 104 protocol (IEC 60870-5-104). The IEC 104 protocol combines the transport layer functions provided by IEC 60870-5-101 (IEC 101 for short) and the TCP / IP protocol, and is suitable for equipment control, information transmission, and status monitoring in industries such as power and urban rail transit. This system employs a high-efficiency data transmission network, such as Ethernet based on the TCP / IP protocol or other industrial communication protocol networks, to ensure fast and accurate data transmission.

[0026] The devices at the device layer communicate with each other through a data transmission network, enabling real-time data sharing and interaction. Multi-protocol gateway devices are used to uniformly convert different communication protocols at the device layer into Internet Protocol (IP) protocols, such as converting the protocols of different devices like PLCs, air conditioners, and elevators into the IEC 104 standard, for unified management and monitoring.

[0027] The management layer 1 includes terminal devices 11 and mobile terminal devices 12, which are connected to the Internet 22. Terminal devices 11 and 12 are used to monitor equipment data in real time and send control signals to the controllers of corresponding devices, thereby achieving remote control. Terminal device 11 can be a computer or similar device, and mobile terminal device 12 can be a mobile phone or similar device. On-duty personnel connect to the data transmission network through terminal devices such as computers or mobile terminal devices such as smartphones or tablets to receive and send data in real time. Through remote monitoring and control functions, on-duty personnel can monitor the operating status of power equipment in real time, promptly detect faults or anomalies, and take corresponding measures.

[0028] The equipment at the equipment layer is interconnected through a high-efficiency data transmission network, namely the Internet, forming a unified information sharing platform. On-duty personnel can monitor various power parameters, environmental conditions, fire risks, energy consumption data, and other information within the substation in real time through terminal devices or mobile terminals.

[0032] The environmental monitoring equipment 32 includes an air conditioning controller 321, a water level detector 322, a fan controller 323, a temperature and humidity sensor 324, a submersible pump controller 325, a louver controller 326, and a smoke sensor 327. The environmental monitoring equipment is responsible for monitoring environmental parameters such as temperature, humidity, and gas concentration within the substation. Staff at the workstation can send control signals to the air conditioning controller, submersible pump controller, louver controller, and other controllers in real time based on the environmental data monitored on-site, in order to adjust the environmental conditions and provide a suitable operating environment for the equipment.

[0033] It is important to note that data acquisition is the foundation and a crucial step for data transmission in intelligent power equipment. Real-time data such as voltage, current, and power are collected through sensors and other devices. This sensor-collected data forms the basis of the substation equipment status monitoring data, and its accuracy, timeliness, and stability must be ensured. Data acquisition can be performed via wired or wireless methods. Wired methods, such as using an RS485 interface, transmit data to the data acquisition unit. Wireless methods, such as using Bluetooth, Wi-Fi, or wireless sensor networks like 4G / 5G, transmit data to a multi-protocol gateway device, which then performs protocol conversion.

[0034] The power monitoring equipment 33 includes a comprehensive protection device 331, a switch status detection module 332, and a power monitoring multi-functional instrument 333. The power monitoring equipment can acquire parameters such as voltage, current, and power of the power grid in real time, and monitor these parameters through terminal devices or mobile terminal devices to ensure the stable operation of the power grid. The power monitoring multi-functional instrument is a conventional multi-functional instrument.

[0039] In this invention, data preprocessing is a crucial step in improving data quality and usability, primarily including data cleaning, data denoising, and data fusion. First, errors, interference, and redundant information are removed from the data to ensure accuracy. Noise reduction algorithms are used to remove noise, improving the signal-to-noise ratio and bringing the data closer to the true value. Then, data collected from multiple sensors are integrated to obtain more comprehensive and accurate data, providing a more reliable basis for fault prediction and equipment maintenance. The above data processing is mainly performed by a data server or cloud server. Based on the existing system, various tools for collecting and integrating dispersed data are developed to form a unified data specification management standard. An object-based data processing mathematical model is established to realize the interrelation of system information, forming a management center for the information area. General scheduling data visualization technology is used to provide users of power automation systems with convenient data analysis, processing, and handling methods. A scheduling data comprehensive processing information system based on user-defined rules is developed and implemented to achieve data reuse and unlock its potential value. Finally, horizontal scheduling data interface technology is developed to avoid multiple data overlaps and duplicate outputs by improving and unifying external scheduling interfaces. A standard interface for vertical data scheduling between upper and lower levels is established, constructing a pyramid-shaped, three-dimensional data system across a wide area to ensure smooth data flow between systems at all levels. Encryption technology is used to encrypt and decrypt data, ensuring it is not eavesdropped on or tampered with during transmission. Secure data transmission protocols and network protection systems are established to improve the system's resistance to attacks. Efficient data compression and transmission algorithms are used to reduce data transmission latency and bandwidth consumption.

[0040] This invention achieves real-time data sharing and interaction between various systems through a high-efficiency data transmission network, the IEC 104 protocol, a multi-functional protocol gateway, data acquisition equipment, and support for terminal and mobile devices. This invention not only significantly reduces the workload of power system operators and improves work efficiency, but also lowers substation operating costs and improves energy utilization efficiency through intelligent and automated management methods.
