Abstract

The invention discloses a partitional auto-coupling compensation type AC voltage-stabilizing control method. The method is realized through an AC voltage-stabilizer comprising an auto-coupling compensation type main circuit, a sampling comparison unit, a delay protective unit, a triggered strobe configuration unit, a triggering unit, an error detection judgment unit, and a protective driving unit;the auto-coupling compensation type main circuit comprises a compensation transformer, an auto-coupling transformer, a thyristor switch group and a relay protective switch; the triggered strobe configuration unit outputs a trigger control signal according to a delayed triggered strobe control value output by the sampling comparison unit, and the trigger control signal is handed over to the triggering unit to control the on-off of a thyristor in the thyristor switch group. Through the method disclosed by the invention, the partition amount of the voltage input into the voltage fluctuation range of an AC power supply can be adjusted, the compensation way and the compensation precision can be changed; when the interlocking control is realized, the protection on the thyristor switch group isstarted / stopped according to whether the triggered strobe control value is effective or not, the power supply source of the triggering unit is controlled so as to enhance the protection degree for theabnormity in the work process.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a partition auto-compensation AC voltage stabilization control method. Background technique [0002] The existing compensated AC voltage stabilizer has the advantages of wide voltage stabilization range, almost no waveform distortion, high overall efficiency and strong load adaptability. The principle is to automatically control the switching of different winding coils of the primary winding on the compensation transformer according to the level of the input voltage, using the ratio relationship between the primary side working winding and the secondary winding, or by adjusting the voltage applied to the primary winding , providing bidirectional and multi-level voltage compensation, so as to achieve the purpose of voltage regulation and stabilization. [0003] The disadvantage of the existing compensated AC voltage stabilizer is that when the motor is used to control the ...
