Feedback Control Strategy for Transient Stability Application

Blog Article

Power systems are subjected to a wide range of disturbances during daily operations.Severe disturbances, such as a loss of a large generator, a three-phase bolted fault on a generator bus, or a loss of a transmission line, can lead to the loss of synchronism of a generator or group of generators.The ability of a power system to maintain synchronism during the few seconds after being subjected to a severe disturbance is known as transient stability.

Most of the modern methods of controlling 4-Wheel Rollators transient stability involve special protection schemes or remedial action schemes.These special protection schemes sense predetermined system conditions and take corrective actions, such as generator tripping or generation re-dispatch, in real time to maintain transient stability.Another method is the use of a real-time feedback control system to modulate the output of an actuator in response to a signal.

This paper provides a fundamental evaluation of the use of feedback control strategies to improve transient Comforter Set stability in a power system.An optimal feedback control strategy that modulates the real power injected and absorbed by distributed energy-storage devices is proposed.Its performance is evaluated on a four-machine power system and on a 34-machine reduced-order model of the Western North American Power System.

The result shows that the feedback control strategy can increase the critical fault clearing time by 60%, thereby improving the transient stability of the power system.
