Abstract

This work deals with power quality improvement by using TCTC & STATCOM. When the reactive power of the load is changing continuously, a suitable fast response compensator is needed. STATCOM (Static Compensator) and TCTC (Thyristor controlled tap changer) are two such compensators belonging to FACTS devices. They are used in this work. Models for the STATCOM &TCTC (Thyristor tap changer) are developed using MATLAB simulink. Smooth reactive power control is achieved by varying the firing angle of TCTC system. The aim of this work is to model and simulate thirty bus system using simulink. The simulation results of thirty bus system with STATCOM & TCTC are presented.

Keywords

Abstract

This paper deals with modeling and simulation of Solid State Circuit Breaker using MATLAB Simulink. The Solid State Circuit Breaker is developed using four power diodes and one Silicon Controlled Rectifier. The voltage across the load is sampled and is rectified to obtain the control signal. The closed loop system detects the fault and the Solid State Circuit Breaker is opened by inhibiting the pulses. The results of sustained fault condition and the closed loop condition are presented. The Solid State Circuit Breaker has advantages like arc free interruption and reduced hardware. The aim of this paper is to model and simulate the Solid State Circuit Breaker.

Keywords
