摘　　要：探讨目前的励磁控制器难以适应电网运行方式大幅度变化的原因,阐述电力系统的运行方式可以短期预测的特性,进而提出可介入式励磁控制器。所提出的可介入式励磁控制器与调度中心建立直接联系,调度中心根据电网运行方式,离线制定励磁控制策略,从全局角度出发,在线更新励磁控制器内部程序,以适应电网不同的运行方式。文中给出了一种可介入式励磁控制器的实现方案,并通过Matlab/Simulink仿真,验证了可介入式励磁控制器在提高电力系统稳定性方面的有效性。The current excitation controller can＇t adapt to the large variation of the power system operating mode, the reason for that is discussed. Based on the characteristic that the power system operating mode can be predicted for a short term, a novel excitation controller named with interventional excitation controller is presented. The proposed interventional excitation controller can directly communicate with the Dispatching Center, the Dispatching Center can establish the excitation strategy based on short-term prediction of the power system operating mode offline, and then update the program of the excitation controller online from overall situation. Thus the global optimization excitation control can adapt to the large variation of the power system operating mode. A kind of design scheme of the proposed interventional excitation controller is presented, moreover, the simulation using Matlab/Simulink is carried out, and the effectiveness of enhancing the power system stability is validated.
