Testing and monitoring the parameters and performance of aircraft AC, DC power systems and their components are a general method for finding their anomaly states. To troubleshoot latent faults and guarantee flight security, the testing and monitoring are very important in the maintenance procedure. Virtual instrument technology, computer control technology and variable frequency speed adjusting technology, are used to implement testing and monitoring of the parameters and performance of aircraft AC, DC power systems and their components. The hardware and software design, AC generator output voltage measurement and its anomaly state discrimination are introduced. In order to improve the maintainability and scalability of the system software, LabWindows/CVI is utilized as the development tool. Laboratory. and field test results indicate that the test aecuracy and efficiency are improved; the anomaly state can be detected anti found in time, the accuracy demand of the maintenance regulation is met. This integrated detection system has been employed in the maintenance work of aircraft electrical power systems and good practical application results are achieved.
