Turbo Chain: A New Recovery System Beyond Ethernet ... - Technolec

Moxa White PaperMoxa Turbo Chain• Scenario 1: Wind Power SystemIn wind power applications, communication points, such aswindmills, are usually scattered throughout the entire windfarm. Redundant Ethernet network connections are an idealsolution to bring windmill nodes together and create a reliablecommunication network to remotely collect data, control theequipment, and adjust windmill settings. However, makingnecessary connections often leads to a common problem—thatring redundancy is not able to easily create the entire networkin an efficient way. To do so requires a cost-effective yetultra-flexible topology (refer to the figure below), but typicalring-technologies are too awkward, costly, and inefficient toconveniently link the nodes together. In this case, Turbo Chainis the best solution. It satisfies the application needs for areliable self-healing network (recovery time < 20 ms) andcost-saving deployment, and remains highly scalable andexpandable so that more turbines can be conveniently added inthe future.Copyright © 2009 Moxa Inc.
