    • A method for determining the contribution of a grid subsystem (12) to oscillations in grid frequency experienced by an external electrical grid (14) in an electrical power network (10). A measurement of grid frequency is taken in the grid sub-system (12) and/or the external electrical grid (14). The measurement(s) of grid frequency can be used to extract oscillations in grid frequency in the grid subsystem (12) and/or the external electrical grid (14). A measurement of active power is recorded on a transmission line (16c) between the grid subsystem (12) and the external electrical grid (14). The phase relationship between the oscillations in grid frequency and the oscillations in active power allows the contribution of the grid subsystem (2) to oscillations in grid frequency in the external electrical grid (14) to be determined.
    • 一种用于确定电网子系统(12)对电力网络(10)中的外部电网(14)经历的电网频率振荡的贡献的方法。 电网频率的测量在电网子系统(12)和/或外部电网(14)中进行。 电网频率的测量可用于提取电网子系统(12)和/或外部电网(14)中电网频率的振荡。 在电网子系统(12)和外部电网(14)之间的传输线(16c)上记录有功功率的测量。 电网频率振荡与有功功率振荡之间的相位关系允许确定电网子系统(2)对外部电网(14)中电网频率振荡的贡献。

    • An advertising device is provided having a bumper sticker assembly and an insulation assembly. The bumper sticker assembly has a first side that is semi-resistant to adhesives and a second side having an adhesive applied thereto. The insulation assembly has a flexible, planar insulation member and a panel of release material coupled thereto. Prior to use, or for storage, the advertising device is kept flat with the bumper sticker assembly releasably coupled to said release material. The advertising device may be used as a cup holder by removing a portion of the insulation assembly, thereby exposing a strip of adhesive, wrapping the advertising device around a container and adhering the strip to the bumper sticker assembly first side. Alternatively, the entire insulation assembly may be removed and the bumper sticker assembly may be used as a traditional bumper sticker.
    • 提供具有保险杠贴纸组件和绝缘组件的广告装置。 保险杠贴纸组件具有对粘合剂半耐性的第一侧和具有施加到其上的粘合剂的第二侧。 绝缘组件具有柔性的平面绝缘构件和与其连接的释放材料的面板。 在使用或存储之前,广告装置保持平坦,保险杠贴纸组件可释放地联接到所述释放材料。 该广告装置可以通过去除绝缘组件的一部分而被用作杯架,由此露出一条粘合剂条,将广告装置包围在容器上,并将条带粘附到保险杠贴纸组件第一面上。 或者,可以将整个绝缘组件移除并且保险杠贴纸组件可以用作传统的保险杠贴纸。
