Transformer control system and method

Abstract

The invention provides a transformer control system and method and belongs to the technical field of transformer control. The transformer control system of the present invention comprises a first control switch, a parallel transformer group, a second control switch, a data acquisition module and a control processing module. A data acquisition module acquires the voltage and / or current signals of auser-side circuit and sends the signals to the control processing module. The control processing module generates a switch control signal according to the voltage and / or current signals of the user side and the performance parameter of the parallel transformer group to control the synchronous operation of the first control switch and the second control switch to control the working state of the parallel transformer group. The transformer control system of the invention is economical and practical, and has good safety, reliability and stability.

Description

technical field [0001] The invention belongs to the technical field of transformer control, and in particular relates to a transformer control system and a control method. Background technique [0002] In recent years, affected by factors such as the country's new rural construction, rural economic development, and the policy of sending household appliances to the countryside, the electrification level of residents' lives has gradually increased. digit growth. The rural power grid is facing a greater degree of pressure, and the load carrying capacity and voltage location capacity are obviously insufficient. Especially during peak power consumption in summer and when migrant workers return to their hometowns during holidays, the capacity of the original power transformer is likely to be insufficient, the reliability of power supply is reduced, the economic effect of operation is reduced, and even overloaded operation, etc., often cause power cuts. [0003] The solution to c...

Problems solved by technology

If the selected capacity is too small, the transformer will be overloaded and the overload loss will increase, and the final result will be to burn the transformer; if the capacity of the distribution transformer is too large, the phenomenon of "big horse and small cart" will appear, the transformer cannot be fully utilized, and the no-load loss will increase.
