Design And Implementation Of Generator-Transformer Based On ARM

Generator-Transformer is the basic measurement instrument for energy measurement and relay protection in the electric power system. Its characteristic of volt-current is very important for the Generator. In this paper, embedded technology is applied to develop the device for measuring the volt-current characteristic of Generator-Transformer. The device gains an advantage over the old-fashioned ones based on the 8-bit Single Chip Micyoco. In this thesis, ARM processor which has high ratio of performance to price,μC/OS-II real-time operating system which is free and stable are introduced.The system mainly complete the functions of test online, setting parameters, inquiry data, communication by UART and also. This paper finishes the software design and implementation of such functions. Especially, the design of displaying the volt-current characteristic line in the function of test online is completed based on the study in the work flow of the display controller, and then the result is accordance with the actual one and the dynamic line for monitoring the status of power equipment. In addition, it is also introduced how to simulate the virtual environment of measurement on PC machines in the paper, which used for the communication between the system and the PC machines by UART.In the end, we can draw the conclusion that the generalization of the new instrument facilities the test of power mutual inductor greatly and enhances the power system productivity with the high measurement accuracy based on the practical application of this instrument in one year.
