Abstract

The invention discloses a control method and system for dual transformers, which is used for detecting a running state of the system and selecting a corresponding scheme according to the running state. When a low-voltage side of each transformer losses voltages and trips, power supply can be automatically restored within relatively short time, a power supply worker does not need to run to a site for manual operation, and reliable, safe and economic running is truly achieved.

Description

technical field [0001] The invention relates to the field of automatic control of power systems, in particular to a double transformer control method and system. Background technique [0002] With the development of the economy, the user's demand for electricity has increased, and higher requirements have been put forward for the reliability of power supply. In many places in China, dual transformers serve as backup for each other to supply power to users, and the switching of these transformers is done manually. Since no intelligent control measures are taken, once a fault occurs inside the transformer or its high-voltage side, fast fault isolation and user power supply restoration cannot be achieved. Contents of the invention [0003] The purpose of the present invention is to provide a double transformer control method, overcome the existing problems in the prior art, and provide a method capable of intelligently monitoring and controlling the operation status of the d...
