Abstract: The present invention is concerned with the combined voltage or power flow control and damping of electromechanical oscillations in an electric power system (2) by Flexible AC Transmission System (FACTS) devices (20) or High Voltage DC (HVDC) transmission devices. To this end, information about a state or operating point of the power system is generated from suitable second system signals (y 2 ) and a control parameter (cp) of a FACTS controller (1) is derived therefrom. The control parameter and a first system signal (y 1 ) are used in the calculation of a control command (u) defining the settings of the FACTS device. Following a change in the state of the power system such as a change in the topology of a transmission network, poorly damped or even unstable oscillations are avoided by appropriate re-tuning of the control parameter of the damping or stabilizing equipment.

Abstract translation: 本发明涉及通过柔性交流传输系统（FACTS）装置（20）或高压直流（HVDC）传输装置的电力系统（2）中的机电振荡的组合电压或功率流控制和阻尼。 为此，从适当的第二系统信号（y 2> 2）产生关于电力系统的状态或操作点的信息，并且从其导出FACTS控制器（1）的控制参数（cp） 。 在定义FACTS设备的设置的控制命令（u）的计算中，使用控制参数和第一系统信号（y1> 1）。 随着电力系统状态的变化，例如传输网络拓扑的变化，通过对阻尼或稳定设备的控制参数进行适当的重新调整来避免差的阻尼或甚至不稳定的振荡。
