Abstract

In this paper, an electromagnetic transient model of Fixed Capacitor/ Thyristor Controlled Reactor (FC-TCR) is developed and applied to the study of transients due to load variations. The work is then extended to custom power equipment, namely Distribution Static Compensator (D-STATCOM) and Dynamic Voltage Restorer (DVR) aimed at enhancing the reliability and quality of power flows in low voltage distribution networks. A new PWM based control scheme that requires only voltage measurements and no reactive power measurements has been proposed for both the custom controllers. PSCAD/ EMTDC simulation tool is used for model implementation and to carry out extensive simulation studies. Comprehensive results are presented to assess the performance of each device as a potential custom power solution.
