(Editors at Energy Analytics Institute, 3.Jan.2025) — Harbin Electric Corporation, involved in power generation technology, achieved a significant milestone in hydropower technology with the successful welding and manufacturing of the world’s largest single-capacity and largest-sized impulse turbine runner.
The engineering feat led to the launch of the globe’s first 500 MW single-capacity impulse hydroelectric generator set at the Zhala Hydropower Station, Harbin said 3 Jan. 2025 in an official statement.
“The achievement marks a major breakthrough in China’s research and development of high-head, large-capacity impulse hydropower units, positioning the country at the forefront of global innovation in this field,” Harbin said.
The hydraulic turbine runner functions as the “heart” of the hydroelectric generator unit at the Zhala Hydropower Station, a critical component of Electricity Transmission of China’s Xizang project. The runner supplies the essential power for the unit to achieve a rated output of 500 MW.
Under the direction of the project’s owner China Datang Corporation, Harbin Electric Machinery Company has independently developed the state-of-the-art impulse runner, boasting energy conversion efficiency that meets world-class standards.
The runner is constructed with a forge-welded structure that includes one hub forging and 21 bucket forgings, resulting in a post-welding weight of 90.8 tons.
