access icon free Algorithm for adaptive single-phase reclosure on shunt-reactor compensated extra high voltage transmission lines considering beat frequency oscillation

Received 02/08/2017, Accepted 17/04/2018, Revised 19/02/2018, Published 25/04/2018

The existing technique of fault state recognition for adaptive single-phase reclosure is severely impacted by the transient beat frequency oscillations after the secondary arc being extinguished in a shunt-reactance compensated line, due to the resonance between the equivalent capacitors and compensating inductors. The characters of fault phase terminal voltage and neutral small reactance voltage are analysed, and the differences of fault phase terminal voltage between the two fault states at recovery voltage stage are compared. Considering that there are some misjudged zones caused by beat frequency oscillation on the fault phase voltage, the neutral small reactance voltage is taken as a base value, and the ratio which uses the difference of calculated and measured on fault phase terminal voltage to neutral small reactance voltage is detected through a beat frequency cycle. Only when all ratios are >1 at the sampling points, a permanent fault is identified. If the ratio of a sampling point is <1, the transient fault is identified, and the reclosing command is issued after a determined delay. The simulation results show that the algorithm can distinguish the fault state under different compensation degrees effectively, and be free of different loads, fault locations and fault resistances.
