Abstract: A method is disclosed for monitoring at least one subsea electric machine supplied by a system for electric power transmission. The system has a power supply, a controller and an AC power line connecting the at least one machine with the power supply. The method comprises the steps of: receiving at the controller, high speed data from at least one subsea sensor arranged between the subsea side of the AC power line and the at least one subsea electric machine, wherein the high speed data includes measurements of an electrical parameter for the at least one machine; and comparing the one or more measurements to a predetermined value. Asystem for electric power transmission arranged for operating at least one subsea load or electric machine is also described.

Abstract: The invention concerns a system for operating an electric machine and a method for protecting an operation control unit in such a system. The system comprises an operation control unit (20), an alternating current cable (16) connecting the machine (30) with the operation control unit and an electric short-circuiting arrangement (26). This arrangement is connected to terminals of the operation control unit facing the cable and short circuits these terminals based on a detected overvoltage.
Abstract translation: 本发明涉及一种用于操作电机的系统和用于保护这种系统中的操作控制单元的方法。 该系统包括操作控制单元（20），连接机器（30）与操作控制单元的交流电缆（16）和电气短路装置（26）。 这种布置被连接到操作控制单元的面向电缆的端子，并且基于检测到的过电压使这些端子短路。

Abstract: The invention comprises a drive controller arranged to provide electrical power from a power supply (10) to a machine (8) or load, over a long AC power cable of the order of kilometers. The drive controller (4) is arranged with circuits and/or control processes to provide AC current at a constant ratio of voltage and frequency to said machine (8) or load. The drive controller maintains voltage and frequency at the machine terminals despite fluctuations in voltage and/or frequency that would ordinarily be caused by the load. This is done by estimating the voltage and current at the machine terminals and adapting the drive controller output accordingly to actively vary the converter output dependent on the load of the machine or other load. In other aspects of the invention a method and a computer program for carrying out the method are described.
Abstract translation: 本发明包括驱动控制器，该驱动控制器被布置成通过大约数量级的长的交流电力电缆提供从电源（10）到机器（8）或负载的电力。 驱动控制器（4）布置有电路和/或控制过程，以向所述机器（8）或负载提供恒定电压和频率的AC电流。 尽管通常由负载引起的电压和/或频率波动，驱动控制器仍保持机器端子的电压和频率。 这是通过估计机器端子处的电压和电流来实现的，并相应地调节驱动控制器输出，以根据机器或其他负载的负载主动地改变转换器输出。 在本发明的其他方面，描述了用于执行该方法的方法和计算机程序。
