Control system for vector regulation of power flows in medium voltage network

Abstract

Abstract The article is devoted to the device for automatic control of power flows in smart grids of medium voltage. A description of proposed method of vector regulation of power flows in a power transmission line using a solid-state voltage regulator (SSVR) is given. SSVR allows one to adjust the current in the line by introducing an additional EMF and changing the voltage drop across a network choke with known electrical parameters. A vector diagram of voltages and currents is given, explaining the principles of forming parameters of the current of the network choke. The Vector In and Vector Out virtual instruments for controlling the SSVR input and output voltage converters respectively are developed in the LabVIEW. Virtual instruments regulate the parameters of the vectors and implement the control of electrical potentials on the network choke. The test results of the developed control system confirmed the effectiveness of vector regulation.
