The world's largest single-capacity reactors officially began operations in Shanghai on Wednesday, following a successful 24-hour trial period, according to the State Grid Shanghai Municipal Electric Power Company.

The reactors, installed on the Shanghai Yuan Dong-Ting Wei 500 kV transmission line project, address the growing challenge of short-circuit currents in the city's expanding power grid. These currents have become more frequent as Shanghai's 500-kilovolt (kV) network continues to grow in both capacity and scale.

The project includes 24 large-capacity series current-limiting reactors. These units will stabilize current flow, protect power equipment, and enhance the power system's operational stability.

"The successful implementation of this project has solved Lin-gang Special Area's mounting challenges in short-circuit current level, improved the area's power supply reliability, as well as ensured Shanghai power grid's stability and power supply safety," said Zhang You, a project manager of the State Grid Shanghai.
