Wintop Optoelectronics Supports Efficient Operation of 500MW Wind Power Project in Inner Mongolia

1.jpg

In recent years, wind power, as an important backing force for clean energy, has entered a new phase of large-scale, clustered, and intelligent construction. As the installed capacity of wind farms continues to grow, with wind turbines distributed over wide areas and individual units often located several to more than ten kilometers from the booster station, wind turbine operation data and video monitoring services require long-distance, real-time, and stable transmission. This imposes higher standards on the communication network’s reliability, electromagnetic interference resistance, and redundancy protection mechanisms.

The 500MW Wind Power Project in Ulanqab, Inner Mongolia, is one of the key projects in the national clean energy strategic layout and is also a representative project for Ulanqab City to build the "Northern Wind Power Equipment and Energy Demonstration Base." The project has a total installed capacity of 500MW, with 120 large wind turbine units constructed, generating over 1.5 billion kWh annually. It can save about 450,000 tons of standard coal and reduce CO2 emissions by approximately 1.2 million tons each year, playing an important role in optimizing the regional energy structure and promoting green and low-carbon development.

Located in the heart of the Inner Mongolian plateau, the project area has abundant wind resources but complex environmental conditions, including harsh winters, frequent sandstorms, and large temperature differences between day and night, imposing very high protection requirements on wind turbine equipment and communication systems. As a typical large-scale onshore wind farm, the project covers a wide area with numerous devices and densely distributed data nodes. The entire communication system needs to perform multiple tasks such as wind turbine status monitoring, operation data collection, control command issuance, and centralized dispatch across long distances and complex terrain.

Leveraging more than twenty years of industrial communication expertise in the power and new energy industries, Wintop Optoelectronics provided the project with a full-site industrial communication network solution and core switching equipment support. It established a highly reliable, low-latency, and self-healing fiber optic ring communication system to ensure stable aggregation of wind turbine operation data and video monitoring information to the booster station and centralized control center, providing a solid communication foundation for the safe and efficient operation of the wind farm.

Project Challenges and Requirements

The wind farm is located on the Inner Mongolian plateau, characterized by large temperature differences between day and night, frequent sandstorms, and complex electromagnetic environments. Equipment must operate stably long-term under extreme temperatures from -40℃ to +75℃ and ensure communication link stability and real-time data transmission amid strong winds, lightning, and intense electromagnetic interference.

At the system architecture level, the project involves a multi-tiered network structure including the main control center, centralized control stations, booster stations, and multiple wind turbine end stations. Communication equipment must support multi-ring network redundancy mechanisms, fast self-healing capabilities, and remote centralized management to address the wide distribution and difficult maintenance of the wind farm.

Furthermore, to ensure high timeliness for power dispatch and turbine status monitoring, the on-site communication equipment requires millisecond-level fault switching and long-period fault-free operation, placing stringent demands on the industrial switches’ system stability, interface compatibility, and protection level.

Wintop Optoelectronics Solutions

Addressing the stringent requirements of the 500MW Ulanqab Wind Power Project for high-altitude adaptability, large-scale turbine-end access, remote centralized operation and maintenance, and link reliability, Wintop Optoelectronics provided a full-site communication network solution composed of multiple models of industrial-grade switches. A highly reliable communication system structured as "Turbine-End Access Layer — Site Aggregation Layer — Booster Station Monitoring Center" was built to achieve real-time interconnection of turbine status data, video monitoring, and dispatch control commands.

In the on-site network architecture, Wintop industrial switches are mainly deployed on communication links from wind turbine substations to the booster station:

At the turbine-end access layer, 120 RS6112-4GF8GT and 120 RS215-1GF4GT industrial switches are deployed, respectively responsible for local aggregation and uplink access of wind turbine operational data and video monitoring signals;

On the booster station side, 4 CM6124-16GF8GT units are deployed as aggregation switches, performing hierarchical aggregation of two monitoring networks (wind turbine operational data network and video monitoring network) and unified uplink to the monitoring system, enabling centralized management and coordinated control of the entire site network.

The solution employs ERPS (Ethernet Ring Protection Switching) redundancy mechanisms to support millisecond-level self-healing under link failures. When any node or fiber link is interrupted, system communication remains stable without interruption, providing strong assurance for remote control and safe dispatch of wind turbines.

Considering the harsh local environment with sandstorms, freezing temperatures, high altitude, and complex electromagnetic conditions, all devices use industrial-grade wide temperature design (-40℃ ~ +85℃) and feature multiple protections including lightning, surge, static electricity, and salt fog resistance, ensuring stable 7×24-hour long-term operation under harsh conditions.

Through this deployment, Wintop Optoelectronics successfully built a communication network system for the wind farm that is highly reliable, resilient, scalable, and easy to maintain, providing a solid communication foundation for efficient grid integration, centralized monitoring and management, and intelligent operation and maintenance of the wind farm.
