Toward the renewable energy era where the electricity is based 100 % on renewable energy sources, the power systems are experiencing operational challenges due to lack of short-circuit power and inertia support. This may cause a cascade failure or even a collapse of the whole system. In addressing this issue, synchronous condenser as a reborn technology which not only supports voltage regulation but also supplies inertial response and short-circuit power for the systems. This paper validates the synchronous condenser benefit at Talega substation in southern California which is equipped with a modern and advanced control technology for synchronous condensers. Based on the measurement data from phasor measurement unit (PMU), it can be concluded that synchronous condenser is a critical key for the system frequency stability improvement and short-circuit power support of renewable-based systems.
A distinct challenge for any electric utility company, be it investor owned, publicly owned or a cooperative, is to be in compliance with regard to testing requirements of modern protective relays. Documented, periodic testing of relays and other IEDs (Intelligent Electronic Device) in power substations must be carried out in order to comply with the requirements of the local regulatory council.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
