Design And Simulink Research Of Angle Tapping Transformer For Power Flow Control

With the development of electrical power industry, major regional network interconnection is strengthen ceaselessly. In the great interests, but also brings a lot of problems:the irrational distribution of tide, three-phase asymmetry because of increasing electronic devices in power system. In order to minimize the use of device that may result in three-phase asymmetric in power system, to achieve tide control in power system, this dissertation studies a new concept of the angel tapping transformer.This dissertation is a part of the project of Flexible Alterative Current Distribution System (Distribution FACTS, DFACTS) which is belongs to School Fifteenth Special Science and Technology Fund. The key research is the angel tapping transformer for tide control in power distribution network, which is the innovation in this dissertation.The dissertation firstly does some research on the existing power flow control devices(UPFC and phase-shifting transformer), then the concept of angle tapping transformer is put forward with explaining the principle of controlling system flow of this device.And then proposes the physical structure of three-phase column angle tapping transformer,and does the magnetic circuit derivation. The theory feasibility are prove, its feasibility is verified by experiments.Then it mainly designs and produces the combined angel tapping transformer. Base on the software of Matlab/Simulink, establishes the Simulink model matching the body of angel tapping transformer, and focuses on closed and three-machine nine nodes power networks, calls the transformer, measures tide flow and analysis of the tide distribution before and after use of the angel tapping transformer.In the end summarizes the whole thesis.
