电力系统励磁鲁棒非线性控制研究

Robust Nonlinear Control Study for Power System Excitation

针对单机无穷大系统,基于系统的Lyapunov函数,提出了一种新的励磁鲁棒非线性控制策略.仿真结果表明,提出的励磁控制策略可提高系统对动态不确定性的鲁棒性,抑制干扰对系统的影响,提高了电力系统暂态稳定性.

Based on Lyapunov function of the system, a new robust nonlinear control strategy for single-machine infinite-bus power system excitation is proposed. Computer test results show clearly that the proposed excitation control strategy improves system robustness to dynamic uncertainties, attenuates disturbances on the system, and enhances transient stability of power system.
