Description

technical field [0001] The present invention relates to the field of power grids, in particular to an on-load voltage regulating device, a processing method thereof, a storage medium, and a processor. Background technique [0002] At present, most of the 10KV on-load voltage regulating devices used in China are high-voltage three-phase on-load voltage regulating devices. The transformer is Y / Yo-12 connection, three-phase three-column iron core, and the three-phase load imbalance cannot exceed 25. %, there is a neutral point displacement, and the quality of the supply voltage is not high. my country's current 10KV on-load voltage regulation is limited to a small number of users who require high-quality power supply voltage, but the quality of power supply voltage for general users cannot be guaranteed. 7% of electrical equipment, causing users to consume more energy, reducing the service life of electrical equipment, forming a vicious circle, more energy consumption, more con...
