Wind Power Network News: With the popularization of computer application technology and the development of national economic informatization, client/server computing, distributed processing, Internet, intranet and other technologies are widely accepted and applied. Terminal equipment The demand for networking (computers, mobile phones, etc.) is expanding rapidly, and the network is becoming more and more widely used in all walks of life. Among many computer networking technologies, Wireless Network, with its advantages such as no wiring, roaming in a certain area, and low operating cost, plays an irreplaceable role in many applications.
Under the trend of national policies, the rapid development of infrastructure for wind power generation, large-scale grid connection and evaluation of the Internet will immediately bring about a rigid demand for lean production. Informatization is one of the prerequisites for lean production, and the establishment of a wireless network is for information Prerequisite work for road construction. The biggest difference between wind farms and conventional power is their remote location. China Mobile, China Unicom, and China Telecom will never invest in sparsely populated wind farms to establish complete 4G and 5G signal coverage. Self-built wireless coverage will be a must for wind power companies, sooner or later. A problem.
Optional technical solution analysis
Through more than two years of in-depth research and large-scale practice, the author basically summarized three feasible routes.
Technical Route 1: Optical fiber ring (chain) network + wireless AP
Features: RRPP ring (chain) network nodes are stringed together through optical fibers to form a “hand in hand” structure. The network speed is stable, the bandwidth is high, and the cost is low. The required equipment mainly includes POE power modules, industrial-grade APs (need to be configured according to different regional climate environments), wireless controller AC, license authorization, wireless AP, domain control and centralized switch management equipment. The product components are mature and stable.
Disadvantages: There is no mature kit, and the fiber breakage of the old wind farm is serious, so this solution cannot be used.
Technical Route 2: Build a private 4G base station
Features: Establish a private base station, wireless transmission, to overcome the problem of insufficient fiber in the station.
Disadvantages: The investment is relatively high. Compared with the profit of a single wind farm, the input-output ratio is not ideal at the current level of technology, and it is not suitable for mountain wind farms.
Technical route three: optical fiber + MESH technology
Features: It can realize wireless transmission, and the cost can be the same as “optical fiber ring (chain) network + wireless AP”.
Disadvantages: There are fewer mature products, and the uncontrollability of later product maintenance is low.
