Voltage Regulation and Load Control
Transactions of the American Institute of Electrical Engineers, 1934Some of the problems involved in supplying electric power to the business sections of large metropolitan areas are dealt with in this article which describes the development and operation of new methods of voltage regulation and load control by means of which improved conditions are being obtained on the distribution system in New York City.

WHEN THE submerged melt welding process was first introduced 15 years ago, one of its most attractive features was the extremely large welding currents that could be used for making heavy welds in one pass. At that time there were a number of automatic welding machines available for arc welding with bare-wire or coated electrode. None of these machines,

Voltage Control of Vapor Rectifiers
Transactions of the American Institute of Electrical Engineers, 1934Some of the changes to be introduced into the mathematical treatment of rectifier circuits when the fring of the anodes of a rectifier is advanced or retarded by control of the arc are described. The points considered and illustrated by theoretical curves include commutation between anodes, regulation, and wave shape of the output voltage for the more ...

Distribution Feeder Voltage Regulation Control
IEEE Transactions on Industry Applications, 2009Step voltage regulators are the work horse of distribution feeders for maintaining the voltage at every customer's meter to be within the ANSI standards. A step voltage regulator can be viewed as a tap changing autotransformer. This paper will apply a model of the step voltage regulator. The IEEE 13 Node Test Feeders will be used to demonstrate how the

Voltage-Controlled and Current-Controlled Low Voltage STATCOM: A Comparison
RE&PQJInverter-based converters interconnecting DC microgrids and AC-microgrids/grids are in a strong expansion. Besides power exchange, the inverter can be requested to furnish ancillary services and, among them, power factor compensation. This work presents a comparison between voltage control and current control in a low voltage inverter in a STATCOM ...

Economical wide-band voltage-controlled voltage source
International Journal of Electronics, 1980An economical non-inverting voltage-controlled voltage source (VCVS) which employs only two operational amplifiers and two resistors is given. The proposed amplifier has a larger bandwidth than that obtained using the uncompensated the Reddy (1976) and the Geiger (1977) VCVS structures.

Voltage control in medium-voltage distribution networks
14th International Conference and Exhibition on Electricity Distribution (CIRED 1997 - Distributing Power for the Millennium), 1997Voltage control becomes increasingly important in medium-voltage distribution networks. A new tool to optimise voltage control in the medium-voltage distribution network and thus enable utilities to obtain, maintain and guarantee systematically an optimal quality of supply has been developed.
