Abstract: Introduction was made to the key indicator and influence factors of medium-voltage system in east Inner Mongolia power grid. The reliability data from 2011 to 2015 was selected and carried out contrastive analysis. The variation trend and concrete cause of reliability data were analyzed to reflect the influence extent of medium-voltage system and to timely grasp the current circuit, the running state of power facility and the existing potential safety hazard, which provides reference functions for keeping good running state in east Inner Mongolia power grid.
Key words: power distribution reliability; power outage liability cause; evenness indices in five years; middle-voltage system; data evaluation
