Abstract: The invalid adjustment of automatic voltage control system in power grid increases the maintenance costs of primary equipment in substations, furthermore, the primary equipment can't be used due to the exceeding number of adjustment, which decreases the voltage qualified rate. Through the statistics and analysis of past adjustment of automatic voltage control system in Anshun power grid, the reasons that cause invalid adjustment are found out, and various methods of reducing the number of invalid adjustment are put forward, and the effectiveness of the method is verified in practice.
Key words: Automatic voltage control; Invalid device adjustment;Energy saving; Lean management
