Einführung
As nations transition to clean energy, the challenge of transmitting power from remote renewable sources to distant urban centers becomes paramount. A cornerstone of this effort is a new Ultra-High-Voltage (UHV) transmission corridor, the first of its kind dedicated to delivering clean energy from a massive desert solar PV base. At a critical node of this corridor sits a ±800kV High-Voltage Direct Current (HVDC) converter station, responsible for ensuring the stable, efficient flow of power across thousands of kilometers. Maisvch was entrusted to provide the mission-critical industrial network for the station’s intelligent monitoring and auxiliary control systems, guaranteeing operational integrity and compliance with the world’s most demanding power grid standards.
The Challenges: Compliance and Reliability in a High-Voltage Environment
Operating a network within an HVDC converter station presents a unique and demanding set of challenges. The immense electrical fields and potential for interference require a level of robustness far beyond standard industrial applications.
- Strict Compliance with Power Industry Standards: The national power grid operator mandates that all digital equipment must meet exacting safety and performance criteria. The networking hardware had to be certified for IEC 61850-3, the global standard for communication networks in substations. This ensures the devices can withstand high levels of electromagnetic interference (EMI), electrostatic discharge (ESD), and electrical surges common in a high-voltage environment without data loss or hardware failure.
- Zero-Tolerance for Downtime: A converter station is a critical national asset where system failure is not an option. The communication network for monitoring and control systems demanded a highly redundant architecture. A single point of failure, such as a failed switch or a broken cable, could not be allowed to bring down the entire system, as this could disrupt monitoring capabilities and compromise operational safety.
The Solution: An IEC 61850-Certified Redundant Network by Maisvch
To meet these stringent requirements, Maisvch engineered a comprehensive networking solution for the station’s intelligent inspection and auxiliary control systems. The architecture was designed from the ground up for reliability and seamless integration with the national grid infrastructure.
The solution centered on deploying approximately 200 Maisvch industrial managed Ethernet switches in a series of redundant fiber optic rings.
- Data Aggregation and Transmission: Field data from various intelligent sensors, inspection robots, and auxiliary control units is collected by Maisvch switches at the access layer. This data is then aggregated and transmitted via a high-speed Gigabit Ethernet ring backbone to the central monitoring and control center for unified dispatch and analysis.
- Guaranteed Redundancy: By utilizing a ring topology with fast-healing network protocols, the system ensures continuous data flow. If any link or switch in the ring fails, the network automatically re-routes traffic in milliseconds, maintaining system availability without any interruption to the monitoring services.
- Certified Compliance and Integration: Critically, the Maisvch aggregation layer switches are fully compliant with State Grid security monitoring standards and certified to the IEC 61850-3 standard. This certification was a key requirement, guaranteeing that the switches could operate flawlessly in the harsh substation environment and that their data could be integrated seamlessly and securely into the national power system’s SCADA network.
