EVALUATION STUDY ON ASVC AND SVC FOR POWER SYSTEM OSCILLATION DAMPING

Advanced Svc Control for Damping Power System Oscillations

Dynamic reactive power compensation is used to a n increasing extent to improve voltage and reactive power conditions in ac s stems. Additional tasks can also be performed by the i ta t ic Var Compensators (SVC) to increase the transmission capacity as result of employment of SVCs for power oscillation damping. This is of particular importance in the case of weakly coupled power systems. A new ...

Damping of Power System Oscillations Using SVC With HPF Control

In large power systems, low frequency electro-mechanical oscillations often follow the electrical disturbances. Generally, power system stabilizers (PSS) are used in conjunction with Automatic Voltage Regulators (AVR) to damp out the oscillations. However, during some operating conditions this device may not produce adequate damping and other effective alterations are needed in addition to PSS....

GSA to Tune Fuzzy Controller for Damping Power System Oscillation

This paper presents a Gravitational Search Algorithm (GSA) to tune optimal rule-base of a Fuzzy Power System Stabilizer (FPSS) which leads to damp low frequency oscillation following disturbances in power systems. Usually in a rule based fuzzy control system, selection of suitable rules is more difficult, because of its complexity. Thus, to reduce the design effort and find a better fuzzy syste...
