Improvement of Transient Stability of Power System by System Damping Series Resistor (SDSR)

摘要

The system damping resistor is one of the method for improving the transient stability of power systems. The main circuit is the simple construction so that is low cost and is few abnormal surge, and is superior in ability of economy, reliability and maintenance. Conventionally, most of all system damping resistors have adopted the paralleled resistor, whereas the series resistor is used little.In this paper, we investigate the characteristics of the series resistor by comparing with the paralleled resistor. The new control method for system damping series resistor is proposed for improving the transient stability of power systems.
