Improving Loadability in Unbalanced Distribution Network using Flexible Step Voltage Regulator

2023 11th International Conference on Smart Grid (icSmartGrid), 2023
Rapid load growth is increasing the strain on the distribution network, resulting in unacceptable voltage drops. The loadability limits on the distribution network can be enhanced by using voltage control devices.

A voltage quality improvement solution using step dynamic voltage regulator

PowerCon 2000. 2000 International Conference on Power System Technology. Proceedings (Cat. No.00EX409), 2002
The quality of power supply is largely synonymous with voltage quality. Momentary voltage dips and fluctuations are some of the common power quality disturbances in the electrical supply networks. The effects of these disturbances transcend beyond just annoyances for the utility customers but may cause industrial-process interruptions which can incur ...

Control of high-step down voltage converters for voltage regulator modules

2011 8th International Conference on Electrical Engineering, Computing Science and Automatic Control, 2011
New technologies are requiring high step-down conversion voltages. A possible solution to this problem is to use several buck converters connected in cascade; however, a complex control circuitry is required. An alternative solution is to use an n-stage positive output cascade buck converter with a single active switch.

Voltage control of multiple step voltage regulators by renewing control parameters

2014 Power Systems Computation Conference, 2014
This paper presents a novel method of determining the control parameters and a voltage control method for multiple step voltage regulators (SVRs) in a single feeder. The main feature of the proposed method is the updating of the control parameters at constant intervals to minimize the amount of voltage violations and the tap operation times of the SVRs

Digital Control and Instrumentation for Step-Voltage Regulators

IEEE Power Engineering Review, 1985
Voltage regulators, LTC transformers, and switched capacitors control the voltage on a power system within defined limits. The devices used to control such equipment have used analog electronics. With developments in microprocessors, some control devices now use digital electronics because of their improved measurement accuracy, digital readout ...

Design of step dynamic voltage regulator for power quality enhancement

IEEE Transactions on Power Delivery, 2002
The design of step dynamic voltage regulator is considered for the purpose of restoring load voltage without incurring excessive phase angle shift. As a type of custom power device devoid of any significant energy-storage capability, the process of voltage restoration by the regulator has to depend on the power in-feed from an external supply system ...
