Power Substation Automation

Overview

Today's demands on power substations are greater than ever before, challenging operators to ensure reliable, non-stop power supply with reduced maintenance and installation costs. In this context, the networking facilities in electric power substations are being redesigned to accommodate the desires of communities, where the high performance communication network should guarantee very strict requirements and comply with the IEC61850-3 and IEEE1613 power standards to prevent the possible power disturbances and outages. Besides, used in power utilities, the networking equipments are subjected to extremes of temperature and humidity, as well as electrical transients from high voltage switching.

Korenix introduces managed gigabit Ethernet switches for providing highly reliable network communication and real-time monitoring in critical power substation applications. The IEC 61850-3 and IEEE1613 power substation-rated JetNet 5628G modular managed gigabit Ethernet switches with 3 modular slots provide several types of fast Ethernet modules with high fiber/copper optic and gigabit port densities to deliver maximum flexibility and simple interface exchangeability for various network connection needs while reducing the overall connectivity costs. In addition to the fan-less design, ESD and surge protection, the JetNet 5628G supports various power input types, including 90~264VAC, 88~370VDC and 24/48VDC for flexible use in severe conditions of field power constructions.

In the remote sites the JetNet 5012G series are used, which collect the data from the cameras and intelligent electronic devices (IED), and transfer them to the control center through formed gigabit rings. In long-distance areas, the switches use SFP transceivers to further extend the data transmission through fiber connectivity. The high-quality traffic switching without data loss and blocking is guaranteed by the 12.8G backplane of switches with the integrated non-blocking switching function.

To provide users with easy maintenance, Korenix industrial managed switches incorporate LLDP function and perfectly work with the patented JetView Pro i2-NMS for allowing administrators to automatically discover devices and efficiently manage theperformanceof power substation networks. The non-stop operation of the network is achieved through the patented MSR redundancy technology with just 5ms recovery time. With the exclusive MultiRing technology of MSR, users can aggregate up to 12 fast Ethernet and 2 gigabit rings into a single JetNet 5628G and guarantee network reliability in applications with increased bandwidth and expended system. The switches fulfill the high-end management requirements by providing 8 QoS, 256 VLAN, IGMP Snooping, DHCP, LACP, and other advanced management and security features to ensure the high quality and reliable network communication.

Moreover, equipped with rugged design and wide operating temperature, the switches provide reliable data transmission becoming the perfect solutions to resist the severities in power substations.
