Wind power has the fastest growth in the new energy and renewable energy industry, with an annual growth rate of 35%. The annual growth rate in the United States, Italy and Germany is more than 50%. China is rich in wind energy resources with reserves of 3.2 billion kilowatts, and its exploitable installed capacity is about 5.3 billion kilowatts, ranking the first in the world. It is the same level as the exploitable hydropower installed capacity of 380 million kilowatts, and has the potential of commercialization and large-scale development. The Chinese government attaches great importance to the wind power industry, and the short-term goal is to achieve 1.2 million kilowatts of grid connected wind power installed capacity. In the process of network construction of wind power plant, the unique characteristics of the industry, such as the physical distance of the unit and the electromagnetic interference on site, have become the watershed to test the performance of industrial Ethernet equipment of different manufacturers. According to the requirements of wind power plant, the network must have the characteristics of real-time acquisition function, scalability, high reliability, high bandwidth, high-quality network signal transmission and redundancy backup. Combined with the actual situation of the network, the industrial Ethernet switch and optical fiber transceiver of Huashu communication are used to build an industrial optical fiber network.
