Application of Fault Location Method Based on multi-source fault information in Repair of Distribution Network

摘要

Fault location method based on multi-source fault information in repair of distribution network is proposed to make the precision and speed of fault location higher. Firstly a topology description and storage method which is appropriate to distribution network fault location is proposed. Then, based on the topological structure of distribution network, fault information on the distribution network is integrated processed. Fault information grouped and priorities are identified using the association of distribution equipment. Low-voltage fault location is achieved by applying fuzzy set theory in fault message omissions and misstatements situations. Finally, an example demonstrates the effectiveness of this method.
