UN 0004a-P V.1 HEIR 316364 Function of R1: (1) Measurement and comparison unit. Measure the generator voltage signal, convert it into DC voltage signal proportionally, compare with the given DC voltage, and send the motor voltage deviation signal. In order to share the load of reactive power reasonably and stably, the differential adjustment unit should be set up.
(2) comprehensive amplification unit. It is composed of comprehensive amplification link, proportional integration link and adaptor link. The comprehensive amplification step will be a variety of basic measurement output, feedback and auxiliary limit generation, as well as the stability and compensation reaction of various DC signals are amplified comprehensively, output to the proportional integration step. The proportional integral link is processed and output according to the predetermined regulation law. The adaptor process amplifies the signal voltage into a phase shift control signal voltage to control the excitation voltage.
(3) phase shift trigger unit. Accept the output signal voltage of the integrated amplifier unit and change the amplitude of the thyristor trigger control Angle to control the excitation voltage.
(4) stabilized power supply. Convert the input AC and DC power sources into the voltage – stable power sources required by the excitation regulator. The input AC and DC power supply should be able to switch automatically in time.
