Virtual instrument based excitation system testing device

This utility model relates to a testing device of generator excited system based on virtual instrument technology, solving that problems that all the functions of prior measuring device are implemented with hardware or built-in software form, the data processing function is insufficient, the running speed and reliability are poor; moreover, the manufacturing technology of these instruments is complicated, the manufacturing cost is high and these instruments are imported mostly. This utility model can gather, analyze, process, display, store and telecommunicate the testing data of generator excited system accurately and conveniently, thus the information for automatic test and diagnosis of generator excitation can be provided, and the stable operation of electric power system is guaranteed. The superiority and technical effects of this utility model are that the hardware equipment is combined with software programming; installation is simple and configuration of parameters is clear; data gathering is simple and testing panel is realistic and the testing operation is flexible, thus the running speed and reliability of testing system are greatly enhanced.
