    • A system information input means takes in system information and a system state determining means determines states of the system. A component operation state determination means determines operation states of system stabilizing components. A control plan deciding means decides a control plan of the system in consideration of operation states of the system and the system stabilizing components. In deciding the control plan, a swing mode analyzing means firstly analyzes the swing mode at each place of the system on the basis of waveforms of time domain response simulations. Then, a control allotment setting means determines control allotment for each of the system stabilizing components based on the mode analysis and a control parameter setting means control sets the control parameters of each of the system stabilizing components. If plural control plans are obtained, the optimal one is selected based on eigenvalues of dynamics of the system or by evaluating time domain system responses by simulation method. The decided control plan is output to the system stabilizing components by a control plan output means.
    • 系统信息输入装置接收系统信息,系统状态确定装置确定系统的状态。 分量运行状态确定装置确定系统稳定部件的运行状态。 控制方案决定装置考虑系统的运行状态和系统稳定部件来决定系统的控制计划。 在决定控制方案时,摆动模式分析装置首先根据时域响应模拟的波形分析系统各处的摆动模式。 然后,控制分配设定装置基于模式分析确定每个系统稳定部件的控制分配,并且控制参数设定装置控制设定每个系统稳定部件的控制参数。 如果获得多个控制计划,则基于系统动力学的特征值或通过模拟方法评估时域系统响应来选择最优的控制计划。 决定的控制计划由控制计划输出装置输出到系统稳定部件。
