A voltage regulator (VR) is an equipment that maintains the voltage level in a predefined value in a distribution line in spite of the load variations within its nominal power. Three different types of connections are analyzed: 1) wye-connected regulators, 2) open delta-connected regulators and 3) closed delta-connected regulators. To calculate the power flow, the three-phase backward/forward sweep algorithm is used. The methodology is tested on the IEEE 34 bus distribution system. ©2008 IEEE.p. 1 - 6engDistribution systemsThree-phase power flowVoltage regulatorsDistribution linesDistribution networkElectrical distribution systemLoad variationsPower flowsSweep algorithmsVoltage levelsDistributed parameter networksDistribution of goodsLocal area networksVoltage controlVoltage stabilizing circuitsElectric potentialTrabalho apresentado em evento10.1109/TDC-LA.2008.4641843WOS:000263861200156Acesso aberto2-s2.0-67650475164
