Example Embodiment
[0038] Such as figure 1 Shown is the network topology of the entire wind farm communication system of the present invention. The wind farm communication system includes a wind farm ring network and a monitoring network. The wind farm ring network and the monitoring network are Ethernet, and a monitoring network connects multiple wind farm ring networks in parallel, that is, one monitoring network monitors multiple wind farm ring networks.
[0039] Each wind turbine in the wind farm is equipped with a communication controller, and the communication controller exchanges information with the main wind turbine controller connected to it. All communication controllers in a wind farm have two pairs of optical fiber communication interfaces, which are connected end to end through optical fibers to form a dual-channel, bidirectional parallel optical fiber ring network. The entire optical fiber ring network constitutes a local area network, and each communication controller constitutes a ...
