AN ADAPTIVE AUTORECLOSURE SCHEME IN A PROTECTIVE RELAY SYSTEM

摘要

The present invention relates to an adaptive auto-reclosing method. Adaptive automatic reclosing process according to the invention, operating the timer, the secondary arc detecting the extinguishing time and the optimal reclosing time, evaluating the transient stability in real time, if said transient stability FSS (First Swing Stable) is not case sangbyeol (phase-by-phase) reclosing the perform that step, and if the transient stability is FSS (First Swing Stable), and the timer of the time is said optimal reclosing time and equal to the secondary It is greater than the arc extinguishing time, and a step of performing a perfect reclosing. ; Adaptive automatic reclosing process according to the invention after disturbance by changing the reclosing method according to the types and transient stability of a failure, was reduced vibration of the grid generator angle is in serious instability to continue to increase to maintain the stability of the system It can be so. ; Relays, reclosing
