INFLUENCE OF TCSC CONTROL SYSTEMS ON OSCILLATION DAMPING

Abstract

In the world, special attention is paid to determining the stability margins of electrical systems in connection with the high growth rates of demand for electricity. In this regard, special attention is paid to research aimed at improving the stability and dynamic properties of electric power systems, including through the use of modern control methods based on intelligent systems. The application of HVDC and FACTS transmission technologies have added new control methods to the power system, increased the throughput of electrical networks, and improved monitoring capabilities. Power system stabilizers (PSS) are traditionally used to damp electromechanical low-frequency oscillations in the frequency range 0.2–1.5 Hz. This paper proposes the use of thyristor-controlled series capacitors (TCSC) control systems as a oscillations damper.
