REDUCING TRANSMISSION LOSSES BY USING STATIC VAR COMPENSATOR (SVC).

Abstract

The fast growing of cities and population led the industrial section to grow as well, in addition to the domestic loads, this rapid increase in load demand forces power systems to operate under heavily stressed conditions, near critical limits due to economic and environmental constraints . To avoid power systems collapse, improve the voltage stability, and reduce the transmission lines losses, the Flexible Alternative Current Transmission System (FACTS) it used. In this dissertation the Static Var Compensator (SVC) has been represented and discussed. Sudanese national grid is undergoing changes as a result of constant power demand increase, thus stretching it beyond their voltage and thermal limit. This drastically affects the power quality delivered. Transmission systems should be flexible to respond to generation and load patterns, then incorporate this device in Sudanese grid to enhancement the performance. Simulations are carried out using (PSAT) package in (MATLAB) software. The results obtained showed the effectiveness of SVC on voltage profile, power losses and power transfer through the line in the Sudanese national grid.
