Integrated Data Acquisition System for HVDC Converter Stations and Large AC Substations

Abstract

Unreliable and uncoordinated data are commonly the only information available to the engineer who analyzes power system disturbances. A new data acquisition system is now available to provide operational, sequence-of-event and oscillographic fault data. These data are related to a common time base and are made available to a remotely located operator within minutes after an occurrence. Under sponsorship of the Electric Power Research Institute a prototype system, designed for HVDC system applications, has been built, tested and installed at their Prototype DC Link in New York City.
