摘要
对单机无穷大系统,通过适当的坐标变换,基于耗散系统的概念,提出了一种新的通过干扰抑制实现的励磁鲁棒非线性控制策略,在实现过程中不需要任何线性化方法。该控制策略可提高系统对动态不确定性的鲁棒性,可抑制干扰对系统的影响。仿真结果表明,提出的励磁控制策略可提高电力系统暂态稳定性。
With suitable co-ordinate transformation, based on the concept of dissipative system, a new robust nonlinear control strategy via disturbance attenuation for power system excitation is proposed without linearization treatment. The proposed controller improves system robustness to dynamic uncertainties and attenuates disturbances on the system. Computer test results show clearly that the proposed excitation control strategy can enhance transient stability of power system.
