| In this paper, the Chengde city 10 kv power supply reliability distribution network promotion strategy is studied. Firstly, the reliability and reliability of power supply and the reliability of power supply are reviewed and summarized, and the theoretical support and experience of the power supply reliability assessment are summarized; secondly,on the basis of literature research, through the construction of Chengde 10 kV distribution network reliability evaluation index system, Delphi method is used to determine the index weight value, were analysis of the present situation of Chengde city distribution network power supply reliability level; then select index, constructed the distribution network of Chengde city the potential risk evaluation index system, refine the effects of power distribution network of Chengde city an potential risk of all, determine the index weight by AHP, and the Chengde city distribution network power supply was carried out to evaluate the safety, the construction of the model; finally, according to the two evaluation results of the above, from the technical level and management level, put forward to improve the power supply reliability of distribution network 10 kV strategy in Chengde city. The results will help city county distribution network power supply reliability evaluation, network security evaluation, potential risk analysis, and reliability level of ascension and provides reference, is of positive significance. |
