  • Publication number: 20200153359
    Abstract: In a method of compensating for a DC offset of a high-voltage AC output from a Modular Multilevel Converter (MMC) including at least one phase leg, the MMC is connected to a three-phase high-voltage AC grid via a grid transformer. The method includes, in at least one DC offset correcting device, measuring the DC offset by in each of the at least one DC offset correcting device: obtaining a high-voltage AC signal in the MMC, removing high-voltage AC components from the obtained high-voltage AC signal by means of a passive higher-order filter to obtained an analogue filtered signal, converting the analogue filtered signal to a digital signal by means of an analogue-to-digital converter, removing remaining AC components from the digital signal by means of a digital filter to obtain the DC offset, and in a controller comparing the obtained offset with a reference value and forming a control signal based on said comparing.

  • Patent number: 10651755
    Abstract: The present invention proposes a hybrid converter branch operating mode for a Modular Multilevel power Converter MMC with MMC cells in distinct subsets operating according to a “pulse blocked” cell operation mode with DC cell voltage increase or according to a “bypass” cell operation mode without DC cell voltage increase. Repeated cell subset assignment and corresponding alternation of cell operating mode allows to reduce or at least manage a mean deviation of the cell capacitor DC voltages of the converter cells. The invention also reduces no-load losses of the MMC in standby mode and a charging voltage in an MMC charging mode.

  • Patent number: 10644538
    Abstract: An IEC 61850 Network Control Center (NCC) server is provided at a gateway intelligent electronic device (IED) of a Substation Automation (SA) system. The NCC server serves, via the MMS/TCP/IP part of IEC 61850, process data from substation Intelligent Electronic Devices IEDs to a NCC. The NCC server uses functional names for gateway Logical Nodes (LN) corresponding to substation LNs. The functional names are devoid of any reference to a substation IED related name of the substation LNs, but can be automatically translated to substation IED related names in case of changing SA communication and substation IED architecture. Thereby, functional names as defined by the substation section within a SCD file of the SA system are used for the communication link between the gateway IED and the NCC.

  • Patent number: 10642237
    Abstract: The present application relates generally to Volt-VAR optimization for power distribution systems having advanced metering infrastructure (AMI). Distributed energy resources (DER) such as photovoltaic arrays are becoming prevalent in distribution systems. These DER systems inject power into the distribution system which can cause unfavorable changes, such as a rise in voltage across the feeder lines of the distribution system. Existing control proposals suffer from a number of shortcomings, drawbacks and disadvantages. In some instances, traditional controllers for distribution systems with DER systems may require information related to the arrangement of the distribution system which is unknown and cannot be provided by the advanced metering infrastructure. There remains a significant need for the apparatuses, methods, systems and techniques disclosed herein.
