| Abstract |
In this paper a new Dynamic Interphase Power Flow Controller (DIPFC) based on semiconductor
switched devices is described. The fully developed version of this device allows the most flexible control
of the active and reactive power flow. In this article the focus is concentrated on two different variants of
the DIPFC. The first basic DIPFC variant consists of only one thyristor controlled DIPFC-module. This
system is analyzed by an analytic approach based on a transformation into space-phasor and zerosequence
networks for each switching status. The resulting state space descriptions of the different
switching states are coupled into a linear inhomogeneous boundary value problem which can be solved
analytically. A retransformation into natural co-ordinates leads to the time functions of all system
variables and further characteristic parameters like power factors or stability indicators. Therefore the
interactions of the device and the surrounding network can be verified using this calculation technique.
The second variant described in this article concentrates on a more flexible DIPFC structure made up of
two thyristor controlled DIPFC-modules. This device is analyzed based on a Matlab Simulink simulation
model which can be used to demonstrate the basic principle and the fundamental potentialities to control
the active and reactive power flow. |
