On October 10, State Grid Gansu Electric Power Company announced that the Wuqing converter station of the Gansu-to-Zhejiang ±800kV ultra-high voltage direct current (UHVDC) transmission project (Longdian-Ruzhe Project) commenced AC system commissioning on that day, marking the official entry into the system commissioning phase of the project.
The AC system commissioning at the Wuqing converter station effectively tests the safe and stable operation of the converter station’s “heart”—converter transformers, converter valves, and their cooling systems—enabling the AC side within the station to achieve safe grid-connected operation conditions, comprehensively verifying the equipment’s load-bearing operational capacity.
Currently, the 494-kilometer Gansu section of the Longdian-Ruzhe project has been fully connected along the line. The entire project is expected to be completed and put into operation by 2027. Once fully operational, Gansu will be able to transmit over 36 billion kilowatt-hours of electricity to Zhejiang annually, with more than 50% of that electricity from new energy sources, providing strong support for east-west energy coordination and green low-carbon transition.
The Longdian-Ruzhe Project is a key power transmission corridor connecting northwest China with eastern coastal regions, playing an important role in optimizing energy resource allocation and promoting new energy consumption. The project adopts ±800kV UHVDC transmission technology, featuring high single-transmission capacity, long distance, and low losses, and is an important component of the national “West-to-East Power Transmission” strategy.
