Abstract: The accuracy of the time-frequency test in a power system is directly related to the consistency and validity of data acquisition, storage and analysis. On the basis of introducing time-frequency test techniques and aiming at the deficiencies of the current time- frequency test in the power system, an intelligent time-frequency test and analysis system combining software and hardware was developed in this paper. Firstly, the design scheme of the hardware and its characteristics were introduced. In the following section, the development environment, function features and design processes of the software were described. Then the functions of the intelligent time-frequency test and analysis system as well as its business processes were described. Finally, the functionality and performances of the system were verified by a test example.
