    摘要: A protection arrangement for a multiphase uninterruptible power supply system including a vacuum circuit breaker connected in series with an inductive element, where the inductive element includes, for every phase, two series-connected magnetically coupled windings separated by a tap point. The protection arrangement includes one first group of protective components per phase, each first group including a first protective component having a first end connected to a link between the vacuum circuit breaker and the inductive element and a second end connected to a corresponding tap point, where at least one protective component in each first group is a surge arrester.

    摘要: A photovoltaic power plant system for power generation, comprising one or more photovoltaic clusters and one or more modular multilevel converters. Each photovoltaic cluster includes a number of photovoltaic strings connected to one or more MPPT DC/DC, converters connected to a common LVDC, bus. Each photovoltaic cluster includes a DC/DC converter including an input connected to the LVDC bus, and an output connected to a MVDC collection grid. Each of the one or more modular multilevel converters includes an input connected to the one or more photovoltaic clusters via the MVDC collection grid and an output connected to a transmission grid.
