Result analysis of Power Flow Control and Line Deicing Using a Bundle-Controlled Line Impedance Modulator in MATLAB/SIMULINK

Abstract

This paper presents a flexible ac transmission system device under development for the management of power flow under steady-state and dynamic conditions, the bundle-controlled lineimpedance modulator (LIM) in MATLAB/SIMULINK. In its simplest form, an LIM is made of switching modules connected in series with transmission-line segments whose bundles have subconductors insulated from each other. A module contains one switch in series with each subconductor of a bundle and the modules are anchored to dead-end towers in place of yoke plates. Together, with the measurement of sensors and controls, these modules can be used to change series impedances of transmission lines and implement functions, such as deicing and power-flow control. Finally, the LIM performance is analysed.
