本文提出了一种考虑不同电压调节器模型的配电系统三相潮流。电压调节器（VR）是一种设备，其将配电线路中的电压水平维持在预定义值，而不管其标称功率内的负载变化。分析了三种不同类型的连接：1）Y形连接调节器，2）开放三角形连接调节器和3）封闭三角形连接调节器。为了计算潮流，使用三相向后/向前扫描算法。该方法在IEEE 34总线配电系统上进行了测试。
In this paper a three-phase power flow for electrical distribution systems considering different models of voltage regulators is presented. 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.
