PROJECT TITLE :

Novel transformer-type adjustable reactor based on two-port network control

ABSTRACT :

In order to develop an adjustable reactor with rapid and continuous regulation and restricted harmonic output, a unique transformer-kind adjustable reactor primarily based on 2-port network management is proposed. The secondary windings of transformer encompass many switched windings (SW) and a control winding (CW). The equivalent impedance of transformer's primary winding could be regulated arbitrarily by coarse adjustment and fine adjustment. The secondary winding of the unit under thought has 5 sections that can be short circuited by thyristors. The thyristors are operated in such a way as to regulate the quantity of short-circuited sections in operation at any one time, which is used in coarse adjustment. Still fine tuning of the system is provided by current supply inverter feeding a secondary management winding, that is utilized in fine adjustment. The management system is simple and effective primarily based on the two-port network control. The planning and implementation approach of novel reactor are mentioned intimately, and a 630kVA/6kV prototype is verified to style successful through the impedance calculation. The experimental results are given to verify the continuous tuning, quick response and restricted harmonic generation of the novel adjustable reactor.
