Another successful milestone! Sansion Power has successfully completed the full-site commissioning of a 110kV smart substation in Xinjiang, China, marking another major achievement in complex power transmission and smart grid projects.

Following the successful completion of a challenging substation project in the high-altitude region of Tibet, Sansion Power's engineering team has continued to expand its capabilities across Northwest China.

For the Xinjiang project, all substation equipment was successfully commissioned on the first attempt, with zero rectification required and all performance indicators meeting the required standards. The substation was successfully energized and put into operation, demonstrating Sansion Power's strong technical capabilities and reliable project execution in complex environments.

The 110kV smart substation features a sophisticated system architecture, numerous equipment interconnection points and demanding commissioning requirements.

To address the challenges presented by Xinjiang's harsh environmental conditions, including strong winds, dust and significant temperature variations, as well as the complexity of intelligent electrical equipment, Sansion Power developed a dedicated commissioning plan before the project began.

Every critical stage was carefully controlled, from equipment commissioning and system integration to functional verification and final inspection.

The project was completed entirely by Sansion Power's own technical team, covering:

• Substation equipment commissioning
• Smart substation system integration
• Protection and control system verification
• Communication and interconnection testing
• Intelligent system commissioning
• Full-site system coordination and verification
• Final performance inspection

This ensured that the entire commissioning process remained safe, controlled and quality-focused.

From the high-altitude, cold and challenging conditions of Tibet to the dusty, dry and temperature-variable environment of Xinjiang, Sansion Power has successfully delivered major substation projects in some of China's most demanding regions.

The successful completion of these projects demonstrates our experience in:

• High- and low-voltage power transmission and distribution
• 110kV substation construction and commissioning
• Smart substation systems
• Power system testing and commissioning
• Complex-environment electrical engineering
• Intelligent grid infrastructure

These projects also highlight Sansion Power's ability to provide end-to-end engineering, commissioning and technical services across different geographical and environmental conditions.

The successful energization of the Xinjiang 110kV smart substation represents more than the completion of a construction project.

Compared with traditional substations that rely heavily on 24-hour on-site manual operation, the smart substation significantly reduces the need for continuous on-site staffing while improving:

• Smart grid monitoring
• Fault warning and early detection
• Remote operation and control
• Automated operation and maintenance
• Substation management efficiency
• Power supply reliability

The project also helps optimize the local power grid structure and provides safer, more stable and intelligent electricity support for regional industrial development and reliable power supply for local communities.

Sansion Power will continue to focus on power transmission and distribution projects in plateaus, deserts, border regions and other complex environments.

By continuously improving smart substation construction, commissioning and testing capabilities, we are committed to delivering more high-quality benchmark projects with professional engineering, strict quality control and efficient project execution.
