    • An electrical power distribution system having geographically separated plural generation stations and geographically separated loads is improved by dynamically offsetting a nominal real power operating point of a main control system driving a power control element that variably feeds electrical power onto a network of transmission lines between the stations and the loads in response to deviations in frequency and/or phase of alternating current power on the network. The generation station can include an actuator control circuit for driving the control element in response to a power setting signal, the actuator control circuit incorporating a delay component, an offset signal connection downstream of the actuator control circuit bypassing the delay component. Preferably the system further includes means for monitoring a threshold level of the deviations, and means for inhibiting the means for dynamically offsetting until the deviations exceed the threshold level. Thus the real power compensation is applied selectively under high levels of power transfer between geographically distant locations, when the system has a dominant characteristic frequency of oscillation that is lower than an ordinarily dominant local characteristic frequency of the system. Also disclosed are methods for improving stability of a power distribution system.
    • 通过动态地偏移驱动功率控制元件的主控制系统的标称有功功率工作点来改善具有地理上分离的多个发电站和地理上分离的负载的电力分配系统,该功率控制元件可变地将电力馈送到站之间的传输线网络 以及响应于网络上的交流电力的频率和/或相位的偏差的负载。 发电站可以包括用于响应于功率设定信号驱动控制元件的致动器控制电路,所述致动器控制电路包括延迟部件,绕过延迟部件的致动器控制电路下游的偏移信号连接。 优选地,系统还包括用于监视偏差的阈值水平的装置,以及用于抑制用于动态抵消的装置,直到偏差超过阈值水平的装置。 因此,当系统具有低于系统通常占优势的局部特征频率的主要特征频率时,实际功率补偿被选择性地应用于地理位置较远的位置之间的高电平电力传输。 还公开了用于提高配电系统的稳定性的方法。
