Abstract: The auto voltage regulation (AVR) takes an importnt roles in the excitation system of the synchronous generator. The rapid and accurate test method for the AVR is meaningful for the maintenance of the excitation system. In this ariticle, the synchronous generator Park eqution is the basic for the design of the auto-test platform. In this test platform, the computer numerical calculation, the automatic testing technology, the virtual instrument technology and the Labwindows/CVI programming technology is adopted. Through the actual test and the comparison, there are many advantages in the AVR auto-test platform, such as perfect test interms, the short test period, the good universality.
