China has been rapidly expanding wind and solar power capacity, particularly in its northern and western regions with abundant natural energy resources. This expansion creates challenges for grid integration due to the intermittent nature of renewable sources and the need for reactive power management. Synchronous condensers, first used in the 1920s, help handle unused reactive power that oscillates between source and load.
The state-run China Electric Power News said on April 10 that a 35-kilovolt direct-connection rotating machine developed by Dongfang Electric Machinery had successfully passed testing earlier that day. The successful test made Dongfang's synchronous condenser the first in the world to reach such a high voltage, eliminating the need for intermediate step-up transformers to achieve direct grid connection, the report said. This has been driven by the rapid installation of wind and solar power, particularly in the country's northern and western regions, with their abundant natural energy resources. Synchronous condensers were first used in the 1920s to handle the unused reactive power that oscillates between source and load in hydroelectricity generation, according to energy equipment manufacturer GE Vernova.
