针对单机-无穷大电力系统,对自并励励磁系统的仿真进行了研究。通过采用一种非线性自整定参数技术优化常规PID控制,显著提高了仿真机的励磁控制系统的性能,并通过比较发电机升压过程的响应特性,证明了所提控制方法与常规PID控制比较更有简便易行、良好精度和稳定性的特点。
Aimed at the single-infinite-infinite power system, the simulation of self-excited excitation system is studied. By adopting a nonlinear self-tuning parameter technology to optimize the conventional PID control, the performance of the excitation control system of the simulator is significantly improved. By comparing the response characteristics of the generator boost process, it is proved that the proposed control method is better than the conventional PID control More simple, good precision and stability characteristics.
