Leveraging its advanced technology, high reliability, and wide market recognition, our SID-2AS synchronizing device fully meets the stringent requirements of the Qinghai Hainan Base Qinghai–Henan DC photovoltaic project, providing an all-scenario, intelligent synchronizing and grid-connection solution for the project.

To address the extreme environmental conditions of the Qinghai Hainan Base—high altitude (3,000 m) and low temperatures down to –30°C—the SID-2AS synchronizing device adopts dual-channel software and hardware interlocking and multi-level fault-tolerant technologies, ensuring fault-free operation under harsh conditions and meeting the project’s demanding reliability requirements.

Facing the project’s complex grid-connection scenarios—including three 330 kV collector substations (with breaker-and-a-half schemes and double-busbar configurations) and multiple photovoltaic array sections across different contract packages—the solution integrates the SID-2X-B synchronizing point selector with automatic multi-point selection. This enables the SID-2AS to automatically adapt to different substation synchronizing parameters. Through digital phase-angle calculation and voltage compensation, the system rapidly accommodates diverse wiring configurations, significantly simplifying commissioning.

By achieving full-process automation—from parameter matching to grid connection—the solution reduces manual intervention risks and enhances operational efficiency.

Through the combined advantages of high reliability, intelligent adaptation, and automated closed-loop control, the solution helps the project achieve a 30% improvement in grid-connection efficiency and a 20% reduction in operation and maintenance costs under the challenging “desert–Gobi–wasteland” environment, providing a replicable benchmark for similar large-scale renewable energy transmission projects.
