摘要：ABSTRACT: Voltage level control plays a significant role in ensuring the stable operation of power systems in the event of large disturbances and faults, and is thus a significant area of research. This paper investigates the improvement of Voltage level of a two-area multi-machine power system, using STATCOM (Static Synchronous Compensator), UPFC (unified power flow controller) which is an effective FACTS (Flexible AC Transmission System) device capable of controlling the active and reactive power flows in a transmission line by controlling appropriately parameters. Simulations are carried out in Matlab/Simulink environment for the two-area multi-machine power system model with STATCOM & UPFC to analyze the effects of UPFC, STATCOM on Voltage level improvement performance of the system. The simulation results demonstrate the effectiveness and robustness of the proposed STATCOM, UPFC on transient stability improvement of the system.
