Flexible Alternating Current Transmission

Flexible alternating current transmission systems are used since nearly four decades and present very good dynamic performances. The purpose of this work is to study the behaviour of a system where static compensator (STATCOM) is located at the midpoint of a long transmission line functioning in disturbed modes with various levels of load caused by tripping and then, reclosing of the incoming station breaker. The studied model and starting from the analysis of various alternatives will lead to the checking of the aptitude of the STATCOM to maintain the voltage plan and to improve the power flow in electro-energetic system which is the east region of Algerian 400 kV transmission network. The steady state performance of STATCOM’s controller is analysed through computer simulations with MATLAB/Simulink program. The simulation results have demonstrated that STATCOM can be effectively applied in power transmission systems to solve the problems of poor dynamic performance and voltage regulation.   Keywords: STATCOM, reactive power, power flow, voltage plan, breaker automatic recloser.
