Study of voltage level sequence of distribution network in Zhengzhou new district based on AHP

In order to improve the power quality and solve the problem of the low load capacity of 10kV distribution network, the paper analyzed the advantages of using 20 kV voltage grade in distribution network and described the present technical characteristics of distribution network in Zhengzhou. Meanwhile, a complete methodology of comprehensive evaluation of the voltage level sequence is introduced based on AHP. When the method is applied in Zhengzhou new district, through technical-economy comparison of the two voltage levels sequence based on the load density, obtained the conclusion of boosting medium voltage level and put forward the rationalization proposal and basis for the rational scheming of the voltage level in Zhengzhou New district and similar areas.
