Deployment Solution for Industrial Ethernet Switches in the Energy Industry (Wind Power/Photovoltaic): Practical Insights from a Seasoned Perspective

In the energy industry, particularly in the fields of wind power and photovoltaics, industrial Ethernet switches are emerging as the core components for building intelligent and efficient communication networks. As a practitioner with years of experience in the industrial Internet of Things, I understand the importance of deploying industrial Ethernet switches to achieve optimal performance and reliability in complex and ever-changing energy environments. This article will share deployment solutions for industrial Ethernet switches in wind power and photovoltaic scenarios.

1. Wind Power Scenario: Building a Solid Foundation for Communication in Extreme Environments

1.1 Environmental Adaptability: The Dual Challenge of Wide Temperature Range and Protection

Wind farms are typically located in open areas, facing multiple challenges such as extreme temperature variations, intense lightning strikes, mechanical vibrations, and electromagnetic radiation. For example, in Arctic or desert regions, industrial Ethernet switches need to have a wide operating temperature range from -40℃ to 85℃ and an IP40 or higher protection rating to withstand sand, dust, and rain erosion.

Practical Case: A certain offshore wind power project adopted PUSR's USR-ISG series industrial Ethernet switches. Their fanless design, all-metal enclosure, and wide temperature characteristics ensure stable operation in extreme environments.

1.2 Redundant Network Design: Ensuring "Zero Interruption" in Communication

In wind farms, the distance between wind turbines and the control center can be tens of kilometers. A single link failure may lead to data loss. By deploying switches that support ring network self-healing protocols, such as the USR-ISG series, path switching within 20ms can be achieved in case of fiber optic cable breaks, preventing the loss of inspection data.

Deployment Key Points:

• Ring Topology: Adopt a ring network structure to ensure that a single point of failure does not affect overall communication.
• Redundant Power Supply: Dual power input design to avoid network interruptions due to power failures.
• Fast Self-Healing: Choose devices with a self-healing time ≤50ms to ensure real-time transmission of critical data.

1.3 Security Protection and Remote Operation & Maintenance: The "Invisible Shield" for Data Security

Wind farm equipment is distributed across a wide area, making remote monitoring and data security crucial. The USR-ISG series switches support VLAN isolation, ACL access control, and IP/MAC binding functions, effectively preventing unauthorized access and data leakage. Additionally, through port mirroring and traffic control functions, network status can be monitored in real-time, simplifying the operation and maintenance process.

Practical Case: A certain wind farm achieved real-time data collection and remote monitoring of wind turbine data by deploying USR-ISG switches, improving operation and maintenance efficiency by 40% and reducing fault response time to minutes.

2. Photovoltaic Scenario: Achieving Efficient Data Collection in Complex Environments

2.1 Device Compatibility: Connecting the "Last Mile" of Photovoltaic Systems

Photovoltaic power plants involve various communication protocols among inverters, combiner boxes, DC cabinets, and other equipment. Industrial switches are required to achieve unified access. The USR-ISG series switches support multiple protocols such as Modbus and Profinet, enabling seamless integration of equipment from different manufacturers and reducing integration costs.

Deployment Key Points:

2.2 Long-Distance Transmission: The "Data Bridge" Spanning Geographical Barriers

Photovoltaic power plants cover large areas with equipment distributed across a wide range. Industrial switches are required to achieve long-distance data transmission. The USR-ISG series switches support single-mode fiber optic transmission up to 20 kilometers, ensuring real-time data return from deep underground or remote areas.

Practical Case: A certain photovoltaic power plant adopted USR-ISG switches to connect inverters and the control center through a fiber optic ring network, achieving real-time data collection and remote monitoring, and improving power generation efficiency by 5%.

2.3 Data Security and Operation & Maintenance Management: The "Invisible Guardian" for Photovoltaic Assets

Photovoltaic power plant data involves core information such as power generation efficiency and equipment status, requiring security protection and remote operation and maintenance through industrial switches. The USR-ISG series switches support mirror monitoring, traffic control, and a graphical management interface, enabling real-time monitoring of network status and simplifying the operation and maintenance process.
