Power Quality Improvement Using Upfc

ABSTRACT This project deals with digital simulation of 14-bus top administrator governance employ UPFC to improve the agency quality. The 14-bus system with and without UPFC ar stickeringed and simulate victimisation the blocks of MATLAB/SIMULINK. It is the most complex power electronic system for prevailling the power flow in an electrical power system. The real and reactive powers can be easily controlled in power system using a UPFC system. The circuit model for UPFC is developed using rectifier and inverter circuits. Voltage sag mitigation using UPFC is presented. Real and Reactive power with and without UPFC are studied. 1.INTRODUCTION Flexible AC Transmission Systems (FACTS) base on power electronics offer an prospect to enhance controllability, stability, and power transfer capability of AC ancestral disease systems. In recent years, different FACTS controllers, which are be as power elec tronics-based systems or other static equipments that allow control of one or more AC transmitting parameters, hand over performed a wide variety of compensating functions. In general, FACTS controllers can be classified into two distinct genesiss.

The foregoing generation is based on the line-commutated thyristor devices with only gate throw but no gate turn-off capability. Application of this technology started with the tranquil Var Compensator (SVC) in the 1970s, followed by the Thyristor- Controlled Series Capacitor (TCSC). The newer generation of FACTS Controllers is based on the self-commutated voltage-sourced converters (VSC), which utilize thyristors/transistors with gate t urn-off capability, such as GTOs, MTOs, IGCT! s, and IGBTs. The voltage-sourced converter (VSC) technology has been successfully applied in a number of installations world-wide of Static Synchronous Compensators (STATCOM), Back-To-Back STATCOM, Unified office Flow Controllers (UPFC), and transmutable Series Compensators (CSC). The family of VSC-based FACTS controllers also...If you want to get a full essay, put in it on our website: OrderEssay.net
