State Grid Xinjiang Extra High Voltage Branch ±800kV Tianshan Converter Station

Functional Improvement Project for Oil Chromatography Online Monitoring Devices at #1, #2, #3, and #4 Main Transformers and Tuning Transformers. CYG supplied four sets (12 units) of SE3000 Dissolved Gas-in-Oil Online Monitoring Devices for the Tianshan Converter Station, a core hub of the "West-to-East Power Transmission" strategy. The company provided full-process services including customized configuration, system integration, commissioning, and technical support. This achieved real-time monitoring of all gas components dissolved in oil and intelligent diagnosis, facilitating the upgrade of intelligent grid operation and maintenance, while simultaneously providing technical references for overseas projects facing similar climatic conditions.

  • Operation Mode: 7×24-hour uninterrupted operation, with 12 full-load analysis cycles per day

  • Communication Standards: Supports IEC 61850, I2 protocols, and adapts to RJ45, RS485, and fiber optic interfaces

Flag-of-China-01-1

This project represents a benchmark application of the SE3000 device in the core scenario of ultra-high voltage (UHV) converter stations. By overcoming the challenges of extreme environmental adaptation, the project gained high recognition from top-tier users. It not only lays the groundwork for the promotion of similar technologies at domestic UHV sites but also provides technical references for substation projects in overseas regions with identical climatic conditions, holding significant market benchmark value.

Project Details

Serving the national "West-to-East Power Transmission" strategy, the project provided a solution to the pain point of delayed oil chromatography analysis at the Tianshan Converter Station. The team conquered the extreme environmental challenges of Hami by implementing relay protection-grade chassis, sandstorm-resistant air conditioning, and modular design. Utilizing an expert system with dual diagnostic models, the devices met the requirements for high-frequency operation and precise early warning, maintaining stable operation to date. The devices were seamlessly integrated into the station's existing systems and commissioned with high quality on schedule, ensuring the safety of core UHV equipment and setting a model for the intelligent upgrading of energy infrastructure.
