A synchronous condenser is also termed as asynchronous capacitor. This device is generally used to control the grid voltage. Moreover, it also adjusts conditions on the electric power transmission grid. The field of the synchronous machine is usually organized by a voltage regulator in order to either produce or absorb reactive power which is needed to adjust the grid's voltage or to enhance power factor. The synchronous condenser systems deliver an extremely reliable and effective solution to address reactive compensation and voltage sustenance necessities. Moreover, it also provides an optimized solution for cost to the transmission operators as well as performance and operational flexibility. These devices are a key component of the HV transmission substations. They deliver enhanced voltage regulation and stability by providing continuously adjustable reactive power and improved short-circuit strength. Major cooling types of synchronous condenser commercially available are hydro...
