Fault Data Acquisition System and Data Logger for HVDC Compact Terminals. Final Report

摘要

Unreliable and uncoordinated data are commonly the only information available to the engineer who analyzes power system disturbances. The volume of data required is generally very large, and the types of data needed are not readily collectable by station operators. A new data acquisition system that will provide operational, sequence-of-event and oscillographic fault data is now available. These data are related to a common time base and are made available to a remotely located operator within minutes after a disturbance. A prototype system designed for high-voltage direct-current (HVDC) system applications has been built, tested, and installed at EPRI's prototype dc link in New York City. The developed system is also applicable to alternating current substations. (ERA citation 05:027215)
