The paper develops analytical expressions for the admittances and impedances of a Static Synchronous Compensator (STATCOM) as a function of frequency. The expressions include the conventional positive and negative sequence admittance as well as transfer admittances where a positive sequence current generates a negative sequence voltage at another frequency. These results are then corroborated using the tool of electromagnetic transients simulation. The expressions are shown to be valid for six-pulse as well as higher pulse number configurations. The impact of the STATCOM's control system on the admittance is also investigated.
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.
