<p>A METHOD AND APPARATUS FOR CONTROLLING A REGENERATIVE DRIVE HAVING LINE AND LOAD CONVERTERS CONNECTED BY A DC LINK, THE LOAD COVERTER FOR CONNECTION TO AN AC MACHINE, AND THE LINE CONVERTER FOR CONNECTION TO AN AC SOURCE/SINK BY MEANS OF LINE REACTORS, THE DRIVE FOR CAUSING REAL POWER TO FLOW IN THE LINE REACTORS TO CONTROL THE DC LINK VOLTAGE AT A SELECTED DC VOLTAGE AND FOR DETERMINING WHEN A COMMANDED LINE CONVERTER VOLTAGE EXCEEDS A SELECTED MAXIMUM LINE CONVERTER VOLTAGE FOR ALSO CAUSING REACTIVE POWER TO FLOW IN THE LINE REACTORS TO REDUCE THE LINE CONVERTER VOLTAGE REQUIRED TO CONTROL THE REAL POWER FLOW.</p> |
