Abstract

FACTS - an acronym for flexible alternating current transmission systems is a new solution to the operational problems that is will rely on the upgrading of existing transmission level by using the latest power electronic equipment and methods. Among these is the shunt-connected SVC (static V AR compensator) for voltage control which is was first demonstrated in Nebraska and commercialized by GE in1974 and by Westinghouse in Minnesota in 1975 [2]. SVC is a static var generator or absorber whose output is adjusted to exchange capacitive or inductive current to maintain or control specific parameters of the electrical power system (typically bus voltage). Its also can be used to control the V AR compensation, damping oscillations, transient and dynamic stability and voltage stability. The main objective of this project is to improve the voltage level of the system using an SVC. In this thesis, 2 bus and 11 bus system will be designed and simulate in steady-state and transient condition using the Power System Computer Aided Design (PSCAD). Both of the system in each condition again will be simulated, this time the system was installed with SVC. The simulation of the performance comparisons between without and with SVC shows that the system is more efficient when it was installed with SVC. The voltage waveform shows that the voltage level of the system with SVC is close to 1 pu.
