  • Automatic voltage regulator, automatic voltage regulating method, generator excitation system, and power generation system
    Patent number: 10177697
    Abstract: In one embodiment, an automatic voltage regulator includes a detection instruction unit configured to monitor a generator output voltage, and output an instruction signal when the output voltage of the generator 12 deviates from a predetermined range, the instruction signal being a signal of instructing detection of a specifying parameters generated in a generator field circuit of a generator excitation system; a field-parameter detection unit configured to detect the specifying parameters following to the instruction signal; and a comparison calculator configured to calculate a comparison value between the specifying parameters and a predetermined allowable upper-limit voltage-value of each component constituting the generator excitation system.
