Flexible AC transmission using thyristor switched reactor

Project Title

Flexible AC transmission using thyristor switched reactor

Project Area of Specialization Electrical/Electronic EngineeringProject Summary

Summary

The main theme of this project is to make the power distribution system more effective by the means of flexibility in the transmission line. The purposed idea helps to enhance the power quality using “TSR” in case of no load or the low load on the receiving end the voltage increases due to the capacitance in the transmission line due to this the electrical equipment’s can be easily damaged to overcome this problem this purposed idea help to make the flexibility in the power transmission line.

Project Objectives

Introduction

 There are many methods which are normally used for the flexible ac transmission including the TSR,SVC,SCR and others the main methodology behind all these techniques is to improve the power quality of the any electrical system.

In case of TSR we noticed that in case of the low load on the receiving end there is a massive increase in the voltage level due to this there are chances of the breakdown of the electrical system and the appliance. The purposed ideas make the intelligent system which adds the Reactors in parallel manners with the transmission lines in case of high voltage on the receiving end. The power quality of the system is also increased due to this system and the chances of electrical failure will be low.

Benefits of the Project

Literature Review / State of the Art (Relevant Work Section) 

FACTS are AC(alternating current) transmission systems that combines electric & other fixed controls to increase stabilization & maximize capabilities of transmission of power. Basically, FACTS concept is based on the real or considerable incorporation of electric power devices and procedure into the H.V(high voltage) side of network, to make it controllable electrically. 

Basically, purpose of FACTS controllers is to increase the controlling of flow of power on the H.V(high voltage side) of system during both stable and transitory states. In “1988 Dr. N. Hingorani gave the idea of FACTS i.e theory of control of absolute network ” [1]. FACTS receives due to the many economic and technical advantages it promised
