Abstract: Provided are methods for controlling operation of a voltage regulator of a single-phase of a three-phase power system to regulate a measured voltage. One of the methods includes recording a first elapsed time between detecting a first excursion of the measured voltage from an in-band area to an out-of-band area, and a first return of the measured voltage to the in-band area. The method also includes recording a second elapsed time period (dip period) between detecting the first return and a second excursion of the measured voltage from the in-band area to an out-of-band area. If the second elapsed time period is less than a predetermined dip time period, causing a tap position change of the voltage regulator upon expiration of a countdown period initiated upon detecting the first excursion, thereby adjusting the measured voltage to the in-band area while allowing a voltage drop of limited length.

Abstract: A technique for downloading data from a processor unit, such as an inverter control computer associated with a locomotive control system. When the software for the inverter control computer is originally built, a programmer assigns an ID number to all of the possible instrumentation signals that can be downloaded from the inverter control computer. From the complete list of the instrumentation signals, the programmer defines a default set of the instrumentation signals that are downloaded. If a user wishes to change the instrumentation signals that can be downloaded, then the user provides a command signal to the inverter control computer that changes the set of ID numbers of the instrumentation signals to be downloaded.
