Embodiment Construction

[0039] The present invention will be further described below with reference to the accompanying drawings.

[0040] figure 1 This is the system block diagram of the auto-compensated AC voltage stabilizer. The analog-to-digital conversion coding unit samples the voltage of the AC power supply, and outputs the voltage level code value P2 after analog-to-digital conversion; the delay protection unit inputs the voltage level code value P2, Output the delayed voltage level coding value P3 and the non-triggering zone control signal P4; the interlock control unit inputs the delayed voltage level coding value P3 and the non-triggering zone control signal P4, and outputs the triggering control signal P5; the triggering unit according to the input trigger The control signal P5 sends the trigger signal P6 to the main circuit of the auto-compensation type to control the on-off of the thyristor in the thyristor switch group; the error detection control unit judges whether the input trigger ...

Abstract

The invention discloses a method for controlling a self-coupling compensation-type alternating-current voltage stabilizer. The method includes the steps that an alternating-current power voltage is divided into a plurality of voltage level intervals, and one or more voltages of output voltages of a self-coupling transformer are selected through a thyristor switch group and stacked to serve as a magnet exciting coil voltage of a compensation transformer for voltage compensation; whether a triggering control signal for controlling the thyristor switch group is correct or not is judged; when thetriggering control signal is correct, a working power source of a triggering unit is switched on; when the triggering control signal is wrong, the working power source of the triggering unit is cut off, and the input-side power supply voltage of the self-coupling transformer is controlled to be switched off to protect the thyristor switch group. According to the voltage-stabilizing controlling method, whether logical errors of a control circuit occur or not is judged to protect thyristor switches while interlocking controlling is achieved, the protecting effort for anomalies in the working process is effectively enhanced, and the working process of alternating-current voltage stabilizing is more stable and reliable.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a control method of an auto-compensation type AC voltage stabilizer. Background technique [0002] The advantages of the existing compensating AC voltage stabilizer are that the voltage regulation range is wide, the waveform has almost no distortion, the overall efficiency is high, and the load adaptability is strong. 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 transformation ratio relationship between the primary side working winding and the secondary winding, or by adjusting the voltage applied to the primary winding. , to provide two-way multi-level voltage compensation, so as to achieve the purpose of voltage regulation and voltage regulation. [0003] The disadvantage of the existing compensating AC voltage stabilizer is...
