UNDER FACTS AND HVDC TRANSMISSION USING MATLAB
Power today is a basic commodity. In the recent years ecological concerns and high installation costs have put constraints over construction of new plants and overhead lines in many countries, thereby forcing existing system to be used more efficiently. Conventional means result in slow overall control and in the loss of synchronism and serious over-voltages on load buses. Our main objective is to meet the electric load demand reliably while simultaneously satisfying certain quality constraints imposed on the power supply. Generally, this specified level of system reliability and quality is insured in terms of the capacity of the system to meet the aggregate load demand and the ability of the system to withstand the impact of disturbance. A new concept of Flexible AC Transmission system (FACTS) brought radical changes in the power system operation and control. A new technique using FACTS devices linked to the improvements in semiconductor technology opens new opportunities for controlling power and enhancing the usable capacity of existing transmission lines. UPFC and SSSC are examples of such FACTS devices.
