Study on Control Method of Exciting System of AC Generator/Motor in Converter Set

In the paper, study on the exciting system control of AC generator/motor in a converter set is carried out, the control of the exciting current while the AC generator/motor is as a generator running parallel with a power net and in the process that the AC generator/motor is transited from its generating condition into its motor condition is analyzed. Design and operation specifications of the converter set are put forward in light of the commission functions of it, and a exciting current control system with high reliability and good performance for AC generator/motor of the converter set is developed.
