Power system transient stability enhancement by fast valving

Power system transient stability enhancement by fast valving

Power system stability can be enhanced with use of fast valving in steam turbines. Its actuation guarantees a fast reduction of mechanical power in faults and load rejections, reducing the accelerating area (P-/spl delta/) and raising the decelerating area. This article proposes a simple mathematica...

Description
Summary:Power system stability can be enhanced with use of fast valving in steam turbines. Its actuation guarantees a fast reduction of mechanical power in faults and load rejections, reducing the accelerating area (P-/spl delta/) and raising the decelerating area. This article proposes a simple mathematical model for fast valving, which is simulated in a Brazilian thirteen bus system.
