Ethernet Direct Corporation, a professional and primary provider of industrial networking and communication solutions, is pleased to share a project in wind farm application. The wind power industry involves with the design, manufacturing, construction, and maintenance of wind turbines. The wind power industry is growing at a much faster rate of 25% per year, and currently undergoing a period of rapid globalization and consolidation. The end-user is one of the world's leading wind energy consultants in offshore wind, marine renewable and solar energy. The size of on-shore/offshore projects can range from single turbine up to several hundred megawatts, with locations in North & South America, Europe, Africa, Asia and Australasia. The company ooffers the leading SCADA system used to streamline operations for large wind farms with multiple turbine types to enhance the forecasting capabilities and provide ease of operation to the end users.

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.
