Power quality analysis of transmission line by using UPFC controller

Project Area of Specialization Electrical/Electronic EngineeringProject Summary

Transmission system is a system which transfer electrical energy from generating station to the consumer end which is complex and requires careful design and an additional devices for proper operation and controlling of power quality of transmission line.The voltages increase at the receiving side at lightly loaded condition and decreases at heavily loaded condition due to increase of current .If the load is increasing continuously on network then it will result in shortage of reactive power .The traditional way to compensate reactive power is the use of fixed capacitor or mechanical switches but they are slow and create a delay that can damaged the system's equipment .The power electronic based equipment like FACTS(flexible AC transmission system) devices has been inserted in transmission system to improve the power quality and voltage stability of system.The active and reactive power can be controlled more efficiently and have fast switching action and enhanced the voltage stability and power quality of system .The categories of FACTS that can be inserted in transmission line are shunt like SVC,STATCOMs and series compensator like SSSC and series-shunt compensator like UPFC [2] .Unified Power Flow Controller (UPFC) belongs to 2nd generation of FACTS family which consists two voltage source converter (VSCs) and it is most versatile device and can control all the parameters of transmission line .It cani control both active and reactive power .The UPFC can enhance the power quality , increase the utilization capacity of transmission line and can mitigate the power system oscillations..

Technical Details of Final Deliverable

Now a days ,power system become more complex because the use of electricity and the consumers are increasing day by day due increase in growth ,more use electrical equipment in modern life and increase in industrial and residential growth thus, the power quality and a voltage stability of a power system become a main issue.

This project is developing simulation and hardware model of transmission line with UPFC that control the active and reactive power of transmission line and  eliminate the sag and swell from the power system.
