Present achievements and prospects of adaptive auto-reclosure;

The adaptive reclosure of double circuit lines on the same tower and its field test technology are introduced.

Aiming at the limitation of traditional adaptive reclosure,a neural network-based method has been proposed and a three-layer BP neural network has been designed.

A novel method of identifying permanent fault for single-phase adaptive reclosure in transmission lines with shunt reactors is proposed.

Single-phase adaptive reclosing based on phase angle of fault

Through the comprehension of information on double circuit lines, criterion for unserious permanent fault, auxiliary criterion and principle for reclosing according to phase order are combined perfectly, which realize the function of adaptive reclosing on double circuit lines on the same tower, and raise the power system stability in the maximum limit.

This paper provides a new idea and approach for adaptive reclosing in traction supply system.

Virtual technology of self-adaptive reclosures for transmission lines;

We proposed the self-adaptive reclosure with the Bergeron model for UHV long transmission lines.

A new scheme used in single-phase adaptive reclosure is proposed.

ATP simulation results show that the proposed scheme can reliably and effectively distinguish permanent fault from transient fault,and apply to the single-phase adaptive reclosure in transmission lines with shunt reactors.
