Reactive power compensation in distribution system

Thyristor controlled reactor is designed and analyzed to compensate the reactive power demand in balanced and unbalanced loads. The arc furnaces in the region of Aliağa-İzmir are considered the load in this type.This system is preferred in the application of reactive power compensation if the load is varying faster such that the traditional reactive power compensation algorithms having mechanical contactors are not fast enough. The system proposed here is used either with a fix capacitor or with the passive filter circuit.Simulations are carried out in MATLAB / Simulink and PSCAD. The application software is converted from MATLAB into TMS320F2812 eZdsp. The system is built at 3 kVAR rating in the Electrical Machines Laboratory. The PSPICE program is also used to design electronic circuit implemented in this work.
