   摘 要 提出了一种能够有效提高舰船电力系统稳定性的分散鲁棒控制策略。采用发电机机端电压的相角和幅值表示发电机与系统其他部分的相互联系,并且针对由调速器的不稳定调节造成的发电机输入机械功率的波动,以及由电网中无功功率和有功功率的突然变化引起的发电机端电压波动进行了仿真研究,结果表明了这种控制策略的有效性。
 Abstract :A new robust control scheme ,which can be used for decent ralized generator excitation systems and can effectively improve operation stability of warship elect ropower system ,is proposed. By using generator’s terminal voltage magnitude and phase angle to present the interaction among generators ,decent ralized generator excitation control in a multi2generator power system is achieved. The control is realized by utilizing a interference rejection control based on a robust control design approach. Simulation result s show that the proposed robust excitation control strategy can overall improve warship elect ro2power system’s stability.
