Improved static VAR compensator control. Final report
This project examines many of the control aspects of static VAR compensators (SVCS) important for transmission-system applications. Underlying principles and control-design guidelines are given for each of five topics: (1) voltage regulator stability, (2) power swing damping enhancement, (3) second-harmonic interactions, (4) unbalanced faults, and (5) use of mechanically-switched capacitors versus all-thyristor control. Two additional aspects of SVC application emerged during this research: the potential for interaction between the SVC and subsynchronous-torsinal modes of vibration on turbine-generators and interactions between the SVC voltage regulator and subsynchronous resonances associated with series-compensated ac lines.
