The importance of generator circuit-breaker (GCB) selection in pumped storage and synchronous condenser installation

With the increased penetration of renewables in the market and the subsequent need to ensure grid stability, pumped storage power plant & synchronous compensator projects are gaining considerable momentum in Australia. In addition, to increase system strength synchronous condensers are also being installed in our transmission networks. A critical piece of equipment for these types of projects is the generator circuit-breaker (GCB). In pumped storage power plants, the GCB allows the plant to switch from generator mode to pump mode and very severe duties specifically for doubly-fed induction machines (DFIM)  and in synchronous condenser installations it protects synchronous machines while delivering active/reactive power and a varying power factor. During this workshop we will discuss the main GCB selection criteria for these applications as well as the fault rating selection and maintenance aspects that play a key role in ensuring plant availability.
