摘　　要：针对电力系统在发生突发故障后失去同步性的问题,论文采用直接反馈线性化(DFL)技术设计了鲁棒非线性励磁控制器,实现了对电力系统稳定性的增强和容量调节。可以为特定的应用问题选择不同的控制回路。在单机无穷大(SMIB)电力系统模型上进行了仿真,结果表明,在不考虑故障和网络参数变化的情况下,系统的暂态稳定性得到了优化。In order to solve the problem of power system losing synchronization after sudden failure,a robust nonlinear excitation controller is designed by using direct feedback linearization(DFL)technology,which can enhance the stability of power system and regulate its capacity.Different control loops can be selected for specific application problems.The simulation results on the single machine infinite bus(SMIB)power system model show that the transient stability of the system is optimized without considering the changes of fault and network parameters.
