Adaptive Automatic Voltage Regulation in Rural 0.38 kV Electrical Networks

Abstract Development of smart grids for power supply to rural consumers assumes the creation of adaptive voltage regulation systems in 0.38 … 10 kV electrical networks as one of the directions. This paper considers a new approach to create an algorithm for controlling the technical means of regulation and voltage stabilization. The proposed adaptive voltage regulation system allows collecting and processing information on the actual voltage at the consumer inputs and automatically determine the voltage regulation coefficient. The developed mathematical model allows calculating the voltage regulation coefficient depending on the voltage at various points of the 0.38 kV electric network. In the paper there are also new methods of adaptive automatic voltage regulation in the 0.38 kV electrical networks and the requirements to the functional capabilities of this system. The article suggests technical solutions for the implementation of adaptive automatic voltage regulation system. The successful tests of experimental model of this system have been carried out.
