Trans4data industrial Ethernet solution on power planet Distributed Control System
A power plant is an industrial facility used to generate electric power with the help of one or more generators which converts different energy sources
into electric power. As we all know, electricity is a secondary energy source according to which it is obtained from the conversion of primary energy sources
such as fossil fuels, nuclear, solar or wind energy
Distributed Control Systems (DCS) offer an extensive choice of possibilities to effectively support the implementation of complex control systems.
The capabilities of networking these systems provide unprecedented opportunities to improve productivity, reduce impacts on the environment,
and help provide energy independence. To improve the operations of infrastructures, it is essential that control systems use the latest networking
technologies that ensure the continued reliability.
At the field level the industrial switches are used to connect to IEDs and various measuring devices, such as IO sensors, thermometers, humidity controlling equipment …. through their 100Base-TX ports. Using the gigabit SFP interfaces they connect together and form rings to uplink the collected high-bandwidth data to IEC 61850-3 rated series managed switches located in site levels. The distance is extended over optical fiber by installing the SFP transceivers in giga ports. The Rapid Super Ring technology of the switches ensures the reliable data transmission where recovery time is less than 10ms. This redundancy of Trans4data switches provides the necessary level of availability for loop control of the power plant processes.
In the station level, users benefit from the MultiRing technology industrial switches to connect different stations together into another reliable ring,
from where the data is uplinked to the remote substation control centers through extended gigabit fiber ports.
The enhanced management and security of both switch series ensure the high performance of data transmission inside the networks:
specifically the VLAN and Private VLAN guarantee the isolation of traffic and enhance data security, the QoS provides data prioritization,
and IGMP snooping helps transmit data to where it is required. As the switches also offer LLDP, users can automatically perform device discovery,
topology visualization and thus easily and efficiently monitor networks.
The industrial switches are chosen to be used in the project also for the industrial-grade designs. With ruggedized IP40 enclosures and -40~80℃
operating temperature .It can resist severities in power field sites, while in station levels, the industrial switches guarantees reliable operation
by its fanless design and -40~80℃ wide operating temperature.Combining the exclusive MSR ring redundancy into their intelligent design,
the industrial switches become perfect solutions for high performance and highly reliable DCS network construction in power plants
