The power transmission and transformation industry constantly faces new challenges, aiming to provide reliable power supply systems for end users. Various factors, such as equipment failure, adverse environmental factors and unforeseen events, as well as severe electromagnetic interference within substations, can lead to prolonged interruptions in normal power supply services. Therefore, reasonable and effective monitoring of each substation is essential, and providing a reliable and efficient substation network communication platform in extremely harsh environments is particularly important.
IEC61850-3 / IEEE1613 are stringent standards for substation control and protection.
In a substation environment, numerous EMI and environmental factors exist, such as electrical and electromagnetic interference, surges, lightning strikes, static discharge, vibration, and shock. These factors can all lead to information errors or equipment damage during electronic communication. Furthermore, the climatic conditions in substations are exceptional. Substation monitoring rooms are frequently exposed to severe weather conditions such as wind and rain, and these rooms typically lack temperature control equipment. Therefore, network equipment in this environment must be able to adapt to unpredictable and rapid changes in temperature and humidity.
When it comes to network applications in substation automation systems, companies typically require network equipment to meet the IEC 61850-3 and IEC 1613 substation industry application standards. IEC 61850-3 and IEC 1613 standards define the environmental standards and EMI (electromagnetic interference) immunity requirements for the error-free normal operation of network equipment within substations. IEC 61850-3 defines the application standards for "Substation Communication Networks and Systems," while IEC 1613 defines the environmental standards and testing requirements for "Substation Network Communication Equipment."
To build flexible network structures in substation environments and meet the requirements of long-distance or medium-distance data transmission, most substation applications require fiber optic transmission or a combination of fiber optic and Ethernet cables. For short-distance Ethernet interconnects, twisted-pair cabling is typically used, while fiber optic transmission is more suitable for long-distance, wide-area communication. Therefore, administrators in relevant enterprises often use a mix of various cable types to provide long-distance, high-speed, high-bandwidth network transmission. In the high-risk environment of substations, network devices must provide reliable data transmission without any data loss or collisions. Therefore, network redundancy technology must be employed to improve network reliability. Finally, for substation applications, switches must at least provide relevant network control and security management functions, including multicast filtering, QoS, VLANs, and ACL access control lists.
The JetNet 5628G series meets the IEC 61850-3 & IEEE 1613 substation application standards.
The Korenix JetNet 5628G Gigabit Modular Managed Industrial Ethernet Switch has successfully passed all tests for network communication equipment used in substation environments, meeting the IEC61850-3 standard and IEEE1613 environmental certification.
