Abstract

The invention discloses a power distribution network contact effectiveness evaluation method. The power distribution network contact effectiveness evaluation method comprises five steps: step 1, dataacquisition; step 2, data preprocessing; step 3, construction of an association model; step 4, value analysis; and step 5, visual displaying of the data. The power distribution network contact effectiveness evaluation method has the advantages that multi-dimensional data such as power failure frequency and new energy power generation are acquired by utilizing multiple data platforms such as an electric SCADA system, a power utilization information acquisition system, a PMS system and an OMS system; analysis is carried out from five perspectives of distribution line open capacity, voltage quality, protection sensitivity, power supply reliability and new energy access; and an existing power distribution network frame is diagnosed and deeply excavated, so that the contact perception capability of the power distribution network is improved, and limited resources are utilized, and support is provided for contact construction of the power distribution network to the maximum extent, and powercustomers are better served, and the industry competitiveness of companies in the incremental power distribution network market is improved, and a virtuous circle is formed.
