    摘要: A method of controlling a magnitude of an electrical parameter in a power system via a high voltage electron tube. The method includes the steps of measuring the magnitude of the electrical parameter; generating a control signal based on the magnitude of the electrical parameter and on a reference magnitude of the electrical parameter; and switching the high voltage electron tube via the control signal such that the reference magnitude of the electrical parameter is essentially obtained. A control arrangement and a power system is also presented.

    摘要: An electrical chain-link converter system includes a converter phase leg for converting a plurality of DC electrical currents from a plurality of DC power sources to an AC current of an electrical power distribution network. The phase leg includes a plurality of serially connected converter cells each of which is connected to a respective power source of the plurality of DC power sources. The system also includes a control unit associated with the phase leg, the control unit including a processor; and a storage unit storing instructions that, when executed by the processor, cause the control unit to, for each of the converter cells: obtain a dedicated voltage reference for the converter cell; and transmit the voltage reference to the converter cell.
