Wireless transmission solution for offshore wind power

Offshore wind power plants are new types of power plants that use offshore wind resources to generate electricity. In the face of an increasingly difficult oil situation, countries are turning their attention to the huge wind resources of the sea. China is now also gradually involved in the field of offshore wind power generation, and has built a number of offshore wind farms, while new offshore wind power projects continue to be put into construction. During the construction of offshore wind farms, the issue of long-distance communication at sea becomes a problem that has to be faced, and due to the special circumstances, wireless communication becomes the best application choice.

Using wireless technology to build a network

To address the current network construction problems in the wind power industry, the industry‘s advanced wireless mesh network coverage technology can be used to break through the dilemma of no wireless network coverage in wind power stations and to achieve the fusion of audio and video data transmission in wind power station field operations.

Wireless mesh networks can provide anytime, anywhere network access services to meet the complex big data or high requirements for network security environment to carry out wireless data transmission. Due to its peer-to-peer nature, each mesh node can provide a variety of network services.

Wireless self-organising network equipment incorporates WiFi and wireless self-organising network technology with distributed multi-hop functionality, self-healing characteristics and good scalability, low cost, easy maintenance, etc.;

Wireless communication technology is not bound by cables, there is no construction wiring and cable aging problems, deployment is relatively simple and easy to maintain; secondly, the network scalability is good, increasing network nodes only need to increase wireless communication equipment. Therefore, the use of wireless communication networking technology to build the network infrastructure of wind farms can simplify the construction of wind farm networks, network maintenance, reduce the cost of wind farm construction, the progress of China‘s wind power business, the sustainable development of society are of great significance

Scene 1: Wireless networking in offshore wind turbines

Scenario 2: Wireless network between offshore wind turbine and patrol vessel

The land-based AP (transmitter model SY5ac) transmits WiFi and the offshore turbine AP receives it (receiver model SY5ac).

The in-cabin AP (model BL1800XY) is wired to the receiving end SY5ac and then switched to an AP base station for coverage.

The patrol vessel is equipped with the BL5000X, which connects to the in-flight AP base station (model BL1800XY) for fast signal switching.
