As the development of new energy accelerates, wind power, as an important component of green energy, places higher demands on the stability, security, and intelligence of communication networks. Recently, ONV Guangwangshi successfully completed the data and video surveillance system upgrade project for the Changtu Wind Power Company in Liaoning Province. By deploying high-performance industrial switches, they helped the client build a highly reliable, easily manageable, and sustainably scalable communication network platform.

Upgrading Wind Farm Communication Systems Is Urgent

The Changtu Wind Power Project is located in Changtu County, Tieling City, Liaoning Province, in a region rich in wind resources in Northeast China, making it one of the area’s key wind power projects. As the site expands and the need for intelligent management grows, the existing monitoring system faces the following challenges:

· Insufficient network bandwidth, resulting in severe video stuttering and latency;

· Lack of unified power supply and centralized management for multiple camera deployments;

· Poor interference resistance of network equipment, leading to frequent disconnections during extreme weather;

· Absence of remote operation and maintenance capabilities, driving up maintenance costs.

To address these issues, Changtu Wind Power initiated a comprehensive upgrade of its data and video surveillance systems, focusing on enhancing network architecture stability, integrating device power supply, and improving remote centralized management capabilities.

Guangwangshi’s Solution:

Layered Deployment to Build an Efficient Communication Network

ONV Guangwangshi tailored a dual-layer core-access network architecture, with real-time management via a network management platform. The “access layer” employs a ring topology with redundant paths to enhance network reliability, while the “core layer” utilizes routing protocols and access management strategies to optimize data forwarding efficiency and terminal connectivity stability.

Access Layer: Deploy High-Performance e-Network Industrial Switches

High-performance e-network industrial-grade switches—4 electrical ports/2 optical ports or 8 electrical ports/2 optical ports—are used, supporting multi-gigabit access and fiber uplinks to meet the data collection needs at multiple points across the site, as well as the requirements for remote power supply at monitoring locations.

Core Layer: All-Optical 10-Gigabit Three-Layer Routing Core Switch

A high-performance all-optical 10-gigabit three-layer routing core switch with 8 electrical ports and 24 optical ports, capable of 10-gigabit uplinks, is deployed to enable unified scheduling and centralized forwarding of data from multiple subsystems.

Intelligent Cloud-Controlled Hub

Empowered by both the ONV-NMS Management Platform and a mobile app:

▷ Platform side: Visualized management of the entire network’s device topology, with automatic diagnosis of abnormal alerts.

▷ Mobile side: Real-time push notifications of device alarms, triggering immediate operational responses with zero delay.

Remote centralized operations and maintenance reduce costs and boost efficiency, saving over 500,000 yuan annually in on-site inspection expenses.

The entire network boasts excellent scalability and compatibility, leaving interfaces open for future integration of additional sensors and wind turbine monitoring devices, thus laying a solid foundation for the wind farm’s intelligent upgrade.

Stable Performance in Harsh Environments

This project covers multiple areas including wind turbine towers, step-up substations, distribution rooms, and office spaces, where conditions are complex, with large temperature fluctuations and strong electromagnetic interference. Guangwangshi switches operated stably under extreme conditions, demonstrating the following advantages:

· Industrial-grade protection ratings, suitable for wide temperature ranges;

· Robust anti-interference design ensuring stable data transmission;

· Support for redundant ring network technology, enabling fault recovery within seconds;

· Integrated PoE power supply, reducing cabling costs and improving deployment efficiency.

Project Outcomes | A New Smart, Efficient, Low-Maintenance Model for Wind Power Communications

Following the system’s launch, Changtu Wind Power achieved significant improvements in several key areas:

1. Video surveillance smoothness improved by over 90%, with no stuttering or latency;

2. Unified management efficiency of network devices increased by 70%, significantly reducing manpower required for remote operations;

3. Integrated power and network deployment lowered overall cabling costs;

4. Enhanced system stability, maintaining normal operation even in extreme weather;

5. Reserved capacity for future smart wind farm expansion, supporting the connection of more intelligent devices.

6. Outstanding cost-effectiveness: Compared to smaller brands that fall short in quality and reliability—such as poor anti-interference performance and frequent malfunctions—and larger brands whose high prices result in low return on investment, Guangwangshi’s solution strikes an optimal balance between industrial-grade performance and reasonable pricing, offering customers a highly cost-effective choice that significantly enhances overall investment value.

Empowering Green Energy, Setting a Benchmark for Intelligent Wind Power Communications

The successful deployment of this Changtu Wind Power video surveillance system not only validates the exceptional performance of ONV Guangwangshi industrial switches in complex industrial environments but also provides a replicable reference model for digitalization and intelligent upgrades across the wind power industry.

In the future, ONV Guangwangshi will continue to deepen its expertise in the new energy sector, helping wind, solar, energy storage, and other green energy projects build efficient, secure, and intelligent communication infrastructures, jointly shaping a sustainable energy future.
