Smart Power Transmission System Using FACTS Device

Making of smart grids puts mounting pressure on the nation’s aging electric power transmission system. Just planting additional towers and stringing more line won’t practice the nation’s electric power transmission infrastructure to meet up the energy challenges ahead. Smart grids stand geared up to play a much larger role in the energy equation for reduction of transmission line losses with the range of technologies and methodologies now on hand. The FACTS controllers come out with the capability of enhancing transmission system control, reliability, and operation. Shunt Flexible AC Transmission Systems (FACTS) devices have been used in power systems since the 1970s for the improvement of its dynamic performance. This paper will discuss and express how Static Synchronous Compensator (STATCOM) has effectively been applied to power system for efficiently regulating system voltage and thus increase system load ability. This paper investigates the effects of (STATCOM) on voltage st ability of a power system at different positions. STATCOM plays an important role in controlling the reactive power flow to the power network, when it is placed in a long transmission line. The simulation analysis of this paper can be used as guideline for power industry. The study is thereby simulated usin the MATLAB/SIMULINK software and simulation results show that STATCOM is effective in midpoint voltage regulation on transmission line. In this paper comparison is also performed between STATCOM and SVC under fault condition and it isproved that STATCOM have the capacity to provide more capacitive power for the period of a fault than SVC. It is also displayed that STATCOM shows faster response than SVC.
