With the advancement of the new energy security strategy and the 14th Five-Year Plan, smart grids have demonstrated enormous potential in areas such as replacing fossil fuels with electricity and constructing multi-energy complementary microgrids. Simultaneously, digital transformation has brought new momentum to smart grids, driving continuous growth in market demand. In recent years, with the rapid development of global energy transition and the digital economy, smart grids have become the mainstream of modern power systems.
The smart grid, also known as "Grid 2.0," is the intelligentization of the power grid. Based on a stable power grid framework, it uses communication network and computer information technologies to intelligently monitor power generation, storage, transmission, transformation, distribution, consumption, and dispatch, achieving a high degree of integration of power, information, and business. In the construction of the smart grid, the observability, controllability, and self-adaptive characteristics of power information all rely heavily on information and communication technologies. Industrial Ethernet technology, with its high reliability, flexibility, and scalability, plays a crucial role in optimizing the connections and information transmission between devices throughout the entire power grid system.
Advantages of Industrial Ethernet Switches in Smart Grids
Real-time stability
Industrial Ethernet switches feature high throughput, low latency, and strong anti-interference capabilities, enabling real-time data transmission and response in smart grids and ensuring their stable operation.
Security
Industrial Ethernet switches employ network isolation technology and advanced security protocols to effectively prevent network attacks. For the large amounts of sensitive data involved in smart grids, they provide data encryption and authentication functions to ensure the security of various smart grid systems.
flexibility
Industrial Ethernet switches support hierarchical network topologies, enabling different parts of the smart grid to operate independently. Furthermore, their modular design allows for flexible adaptation to the ever-changing and upgrading needs of the smart grid, enhancing the overall system's flexibility and scalability.
Supports multiple protocols
Smart grids involve a variety of communication protocols, and industrial Ethernet switches have broad protocol support to ensure smooth communication between various devices and systems.
Remote Management
Industrial Ethernet switches support remote monitoring and management, enabling real-time acquisition of device status, detection, diagnosis, and resolution of network problems, ensuring the continuous and stable operation of the smart grid, and improving the operating efficiency of the smart grid.
Digitalization
Industrial Ethernet switches can be combined with 5G technology to provide higher bandwidth and lower latency, driving the smart grid towards a smarter and more efficient future.
Shanghai Zhaoyue Communication Technology Co., Ltd. boasts extensive experience and a strong foundation in the power industry. Since entering the industrial communication field in 2003, the company has focused on the research and development and production of communication products such as industrial Ethernet switches. Subsequently, it established in-depth cooperative relationships with major domestic and international power automation companies, enabling it to rapidly grow into a leading brand in the power industry. Its products have been widely used in power plants, substations, dispatch centers, and power grid control systems in nearly 30 provinces and regions across China.
Application of Shanghai Zhaoyue Industrial Switches in Smart Grids
Smart Substation
Shanghai Zhaoyue's industrial Ethernet switches are widely used in smart substations. The Cronet CC-5428B-NS series, representing a full gigabit security switch, is specifically designed for smart substations and supports the IEC61850 protocol. It provides 24 10/100M auto-sensing Ethernet ports, 4 1000M SFP expansion slots, and supports rich Layer 2 functions. Through SNMP integration with security monitoring equipment, it transmits switch online/offline information, MAC binding information, user login information, user information changes, configuration change information, and port up/down information to the security monitoring equipment via both passive polling and active reporting. After long-term testing and operation, the equipment has proven stable, meeting the security control objectives of "effectively curbing internal intervention and effectively managing security risks," and ensuring the safe and stable operation of the power grid.

High-precision time synchronization
Time synchronization is crucial in smart grids. Every stage, from power generation and transmission to distribution, requires strict time synchronization. Time synchronization devices ensure that the time of all power plants, substations, protection equipment, and automated control systems within the grid remains consistent. This is essential for preventing grid faults and responding quickly to abnormal events. When a grid fault occurs, accurate time information helps protection equipment quickly pinpoint the fault location, enabling rapid isolation and power restoration, thereby effectively preventing the fault from escalating and ensuring the overall safe and stable operation of the grid.
Shanghai Zhaoyue Communications has launched a solution for PTP time synchronization using the MWG-2620-PTP master clock and MIE-2820-PTP switch, both based on a high-precision PTP time synchronization system using GPS/BeiDou. The MWG-2620-PTP serves as the PTP master clock, distributing the synchronized time to various terminal devices in the network via the PTP protocol. The MIE-2820-PTP switch acts as a relay device in the PTP network, ensuring accurate transmission of the time signal throughout the network.
For systems like power automation and distributed energy management within smart grids, which have even more stringent time sensitivity requirements, Shanghai Zhaoyue offers gPTP switch solutions, exemplified by the Cronet TSN-4812. Through precise clock synchronization capabilities, it achieves microsecond-level synchronization accuracy, enabling various devices in the power system to synchronously collect and process data, thus facilitating power quality monitoring and control and ensuring the stable operation of the power system.
