Nonlinear Control Design of Shunt Flexible AC Transmission System Devices for Damping Power System Oscillation
Problem statement: The disturbance in the complicated network of power system may cause in nonlinear response. Static Synchronous Compensator (STATCOM) is a power electronic based device that has the capability of controlling the line current. This study applies the STATCOM to decrease the over line current in power system during dynamic state. Approach: This study proposes the control strategy...
متن کاملFlexible AC Transmission System Controllers: A State of Art
Electricity market activities and a growing demand for electricity have led to heavily stressed power systems. This requires operation of the networks closer to their stability limits. Cost effective solutions are preferred over network extensions. The flexible alternating current transmission system (FACTS), a new technology based on power electronics, offers an opportunity to enhance controll...
متن کاملCritical Review on Power Oscillation Damping Controllers
This paper presents a complete overview of power frequencyoscillations in power system and the root causes of their generation and how they can be damped. Various methods are been presented to tackle with these oscillations can be damped efficiently and the importance of selection of stabilizing input signal for FACTS devices to damp oscillations and how they can be choosen .
متن کاملOptimum Power Oscillation Damping Improvement Using an Add-on Self Tuning Control System for Upfc Application
This project presents a new addon self tuning control scheme to supplement its conventional PI control system in damping low frequency inter area power oscillations. Low frequency (0.1 to 0.8 Hz) inter-area oscillations are often observed when power systems interconnected through weak tie lines are subjected to disturbances such as faults, line outages and sudden load changes. Power System stab...
متن کاملDesign of A Self-Tuning Adaptive Power System Stabilizer
Power system stabilizers (PSSs) must be capable of providing appropriate stabilization signals over abroad range of operating conditions and disturbances. The main idea of this paper is changing aclassic PSS (CPSS) to an adaptive PSS using genetic algorithm. This new genetic algorithm based onadaptive PSS (GAPSS) improves power system damping, considerably. The controller design issue isformula...
