1. Composition of the excitation regulator Generator semiconductor excitation regulator is mainly composed of three basic units: measurement comparison, comprehensive amplification and phase shift trigger. Each unit is composed of several links. 1) The measurement comparison unit consists of voltage measurement, comparison setting and adjustment. The voltage measurement section includes measuring rectification and filtering circuit, and some have positive sequence voltage filters. The measurement comparison unit is configured to measure the converted DC voltage proportional to the generator terminal voltage and compare it with a reference voltage corresponding to the rated voltage of the generator to obtain a deviation of the generator terminal voltage from its given value. The voltage deviation signal is input to the integrated amplifier unit, and the positive sequence voltage filter can improve the accuracy of the regulator when the generator is running asymmetrically, a...
