Title: Akira Isono: Innovator in Generator Control Technology
Introduction
Akira Isono is a notable inventor based in Hitachi, Japan, recognized for his contributions to generator control technology. With a total of six patents to his name, Isono has made significant advancements in the field of electrical engineering, particularly in the management of generator excitation.
Latest Patents
Isono's latest patents include a method and apparatus for controlling the excitation of a generator. This innovative system samples the voltage, current, and field voltage of a generator connected to an electric power system at predetermined intervals for analog-digital conversion. The data is then processed by a digital computer, which not only computes the Automatic Voltage Regulator (AVR) output but also monitors fault occurrences and variations in generator output. After a fault, the system intensifies field excitation until the generator output power peaks, subsequently reducing excitation to below pre-fault levels once recovery is achieved. Another significant patent is the excitation control apparatus for a generator, which features a terminal voltage control unit that manages field current based on the difference between terminal voltage and reference voltage signals. This apparatus includes various compensation functions to enhance generator performance.
Career Highlights
Throughout his career, Akira Isono has worked with prominent companies such as Hitachi, Ltd. and Hitachi Engineering Co., Ltd. His experience in these organizations has allowed him to develop and refine his innovative ideas in generator technology.
