  • Publication number: 20190288509
    Abstract: A method of discharging a Modular Multilevel Converter (MMC) includes a plurality of phase legs connected in delta configuration. Each leg includes a plurality of series connected submodules, each submodule including an energy storage. The method includes disconnecting the MMC from an electrical grid, discharging the energy storages by means of a circulating current, and reconnecting the MMC to the electrical grid. The discharging includes, for each phase leg, setting a voltage reference, and sequentially selecting submodules in zero state by means of a sorting algorithm for switching each of the selected submodules to plus or minus state until the voltage deviation from the set voltage reference of the energy storage of each submodule in the phase leg is within a predefined range.

  • Patent number: 10416221
    Abstract: The present invention provides a method for current for fault identification in a transmission line and an apparatus thereof. The method comprises the following steps: measuring the real-time values of the currents and the voltages of the other unbroken healthy phase conductors when a single-phase fault occurs; calculating the inductive voltage and the capacitive coupling voltage according to the measured currents and voltages respectively; comparing the capacitive coupling voltage with the inductive voltage multiplied by a factor, in which the multiplication result is used as a self-adjusted threshold based on the real time load condition of the transmission line; and identifying the fault type based on the maximum of the capacitive coupling voltage and the multiplication.

  • Patent number: 10416209
    Abstract: A system and a method for determining the power loss of a transformer. The method includes measuring voltage and current at the primary side of the transformer, calculating input power by multiplying the measured current and voltage on the primary side of the transformer; measuring voltage and current at the secondary side of the transformer, calculate a nominal error ratio, calculating output power by multiplying the measured current and voltage on the secondary side of the transformer. The method further involves calculating a first corrected power loss by means of multiplying the input power with the nominal error ratio and subtract the output power.

  • Patent number: 10418917
    Abstract: A method for generating a combined output waveform (VOUT) in a power inverter system (100) is disclosed. The power inverter system comprises a voltage equaliser (120) having an energy storage element adapted to be charged by a combined output voltage from a plurality of switching units and to add an adjustable voltage to the combined output waveform. A voltage of the combined output waveform is measured, a difference (?) between the measured voltage of the output waveform and a voltage of a target waveform (UT) is determined, and a voltage (UCORR) corresponding to the determined difference is added, by the voltage equaliser, to the combined output waveform so as to improve the matching of the combined output power waveform and the target power waveform.
