Abstract: The voltage control technology of electric excitation synchronous generator has some shortcoming such as parameter drift, unstable workflow and voltage distortion. Which lead to the over-tolerance of control parameters, etc. In order to solve the above-mentioned problems, a digital voltage control technology for electric excitation synchronous generator is introduced. Which measures the True RMS Measurement through AD736 high precision chip, and develops the Generator Voltage Digital Controller through the voltage control technology based on double closed-loop digital PI algorithm. Finally the performance index of the controller has meeted the design requirements, and the anticipated design goal has been achieved after test and verification by experiments.
