A method and apparatus for an electrical bus leveling unit are provided. The electrical bus leveling unit includes a first power supply configured to generate electrical energy having a first set of electrical parameters and a power converter electrically coupled to said power supply. The power converter is configured to be coupled to an electrical bus couplable to a second power supply. The electrical bus leveling unit also includes a controller including a processor that is communicatively coupled to the power supply and the power converter The controller is configured to receive information relating to the operation of the electrical bus from a plurality of sensors, control an output of at least one of the power supply and the power converter to transfer electrical energy to the electrical bus when the second set of electrical parameters on the electrical bus is outside a predetermined range.

A method for providing cooling and power is provided. The method includes providing a cooling unit that includes a first turbine rotatably coupled to a generator by a first shaft and providing a power unit that includes a second turbine rotatably coupled to a compressor by a second shaft. The method further includes coupling the power unit in flow communication with the cooling unit to form a turbine assembly, wherein the first shaft and the second shaft are independently rotatable relative to one another.

Method and system for providing cooling and power

A turbo-generator machine for producing a supply of cooled air and a supply of electric power has a permanent magnet generator fixed to a shaft which is driven by a turbine rotor, the turbine serving to expand air which is supplied thereto. Magnetic bearings support the shaft radially for rotation about a precisely established axis while a magnetic thrust bearing keeps the shaft in a precisely fixed axial position. Power for the magnetic bearings is supplied by the turbo-generator during operation. Generator air gap is sized in coordination with the magnetic bearing air gap, and the generator stator and shaft are sized to minimize leakage flux from the generator to minimize interaction between the permanent magnet rotor and the magnetic bearings.
