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

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.
