Ethernet technology is installed for long distance monitoring, centralized control, and operating capabilities in harsh environments where the wind power farms are usually located. Wind power installations used PLC systems to link to each other and then connected to industrial Ethernet equipments. Data and voice are transmitted in the same network. The importance of installing industrial switches is to be able to visualize and control the entire wind farm plant. To prevent the loss of data transmission, redundant links are established with 300 ms.
Since wind powers are outdoor installations, industrial Ethernet switches should withstand extreme conditions, such as electromagnetic fields and high/low temperatures. A high availability of data network is required in a wind power application. Industrial standard Ethernet switches and converters from Ethernet Direct is the solution. In terms of outdoor installations, HME-623 and RUE-113 comply with IP-31 housing protection, and provide high level of immunity to electromagnetic interference & power supply surges.
For network reliability, HME-623 provides redundant self-recovery mechanism in less than 300ms while RUE-113 offers built-in Link loss forwarding which promptly alarms users in case of port breaks or power failure. Both devices are suitable for an industrial environment, and make the system completely reliable.
