China's Gas Power Generation Company Achieves Stable & Reliable Data Communication Using Korenix's Ruggedized Networking Switches and Computers!

Korenix JetNet switches and JetBox embedded computers have recently been used by a Chinese Gas Power Generating company to provide precise data transfer and maintenance of its overall system. The Modbus TCP/RTU gateway function enabled JetBox 5300 embedded computers to communicate data between various installed Modbus RTU units and SCADA Server. Additionally, through offered fiber ports and the MSR ring redundancy, JetNet 4508f-s switches reliably extended data throughout the widely distributed Power Generation System area while easily integrating with HMI systems via the Modbus TCP/IP. With their smart interface design and ruggedized hardware features Korenix solutions provided cost-effective and highly reliable data communication in China's Power Generation System.

Gas power generation systems are becoming more complex by time as they continue integrating latest cutting-edge technological innovations to provide more efficient operation within systems. With this complexity providing real-time remote management and uninterrupted data transfer is becoming more crucial. This said network administrators are implementing Modbus devices and HMI systems to enhance the network management of the whole Generating system. Considering the severe conditions on the power generation plants, a significant factor for communication device vendors becomes the rugged design that should endure all the environmental impacts, such as vibration, temperature extremes, electromagnetic interference, etc….

A Gas Power Generation System provider in China overcame all these challenges when re-designing its network infrastructure by choosing Korenix' JetNet and JetBox series data communication solutions.

The gas power generation system consisted of 3 main areas that have to be controlled and monitored remotely from the supervisory & control center: the Power Generation station, Gas Pumping station and the Water Flow control area.

To collect all the information from these stations, Korenix JetBox 5300 series embedded computers have been a perfect fit: they are used as Modbus RTU to Modbus TCP gateways to send data from water and gas flow meters, valve controllers, generators… using the RS232 and RS485 serial ports.

To transfer the data from widely distributed areas, the network designer chose to implement Korenix JetNet 4508f-s single-mode fiber switch model, which extends the data collected from JetBox computers up to 30KM through fiber optic ports. Additionally, using Korenix' unique MSR ring redundancy technology, the switches ensure the real-time and reliable data transfer without any loss or system operation failure.

Another key reason for the System Integrator to choose JetNet 4508f-s model has been its support of the Modbus TCP/IP interface, which helps easily integrating the device with existing HMI system in the control room or filed site monitoring system, and therefore managing and maintaining the network more efficiently.

Last but not least, the rugged design of both the JetNet switch and the JetBox computers helps users to install them under tough conditions such as the extreme temperature range (JetNet 4508f-s offers -40~75°C and JetBox 5300 -40~80°C operating temperature ranges), the vibration and electromagnetic interference, and offer stable operation without possible system failure.
