Abstract

The invention relates to the technical field of power, and more specifically, relates to a self balance control method for a commutation switch based on self induction of a transformer area load. Themethod comprises steps: data before and after the action of the commutation switch are collected; a commutation switch action model is constructed; a three-phase voltage estimation system after the action of the commutation switch is obtained; and finally, the data before the action of the commutation switch at present are inputted to the three-phase voltage estimation system, and thus, a commutation switch action scheme can be obtained. Local in-situ three-phase balance of the commutation switch without communication can be realized.

Description

technical field [0001] The present invention relates to the field of electric power technology, and more specifically, to a self-balancing control method for commutation switches based on station area load self-sensing. Background technique [0002] Traditional commutation switches need to rely on communication, and are not suitable for scenarios with long power supply radius or many urban occlusions. At the same time, without knowing the state of the head end of the phase change switch and other phase change switches, how to ensure the action effect of the phase change switch after it is actuated is a difficult problem. Contents of the invention [0003] The purpose of the present invention is to overcome the inability to guarantee the action effect of the commutation switch after the action, and to provide a self-balancing control method for the commutation switch based on the self-sensing load of the station area, which can realize the localization of the commutation sw...
