Abstract:

excitation control system plays an important role in the stable operation of synchronous generator. It can not only ensure the stability of power grid operation, but also ensure the output of higher quality power. AC acquisition is the input of excitation control and an indispensable part of the whole process. Based on this, the AC acquisition system of excitation control system based on STM32F103RCT6 is studied. The idea of modularization is adopted, and C language is used for programming. Firstly, the overall structure of the excitation control system is introduced, then the overall design of the system is carried out, and then the whole project is completed through software design and debugging analysis. The test results show that the overall structure of the AC acquisition system of the excitation control system of synchronous generator designed with STM32F103RCT6 single chip microcomputer as the core is easy to understand, the software of the AC sampling module and the effective value calculation module is also easy to realize, the accuracy in the operation process is high, and it is relatively safe and reliable.
