Abstract: An energy generation system includes a turbine, an electric generator, a step-up transformer, and a converter. The turbine is operable to extract energy from a fluid flow and convert the extracted energy into mechanical energy. The electric generator is operable to convert the mechanical energy from the turbine into AC electrical energy. The step-up transformer is operable to transfer the AC electrical energy at a lower voltage from the electric generator to a higher voltage. The converter is operable to convert the AC electrical energy at the higher voltage to DC electrical energy. The converter includes a converter leg for a phase of the AC electrical energy. The converter leg has an upper arm with a first plurality of sub-modules and a lower arm with a second plurality of sub-modules. Each sub-module is operable to function as a controlled voltage source.

Abstract: Methods, systems, and computer readable media for providing protection of DC building electrical systems are disclosed. According to one aspect, a system for over-current protection of direct current (DC) building electrical systems includes a DC bus for providing DC power to a building and multiple DC feeder conductors for providing DC power to multiple locations within the building. Each DC feeder conductor is connected to the DC bus via a DC protection module having a fuse, a normally closed switch connected in parallel with the fuse, and a circuit breaker connected in series with the fuse and switch, where the switch is controllable to be closed to protect the fuse against transient current conditions and controllable to be open after the transient current conditions have subsided to allow the fuse to operate normally.
