초록

A power electrical system is disclosed to connect a microturbine and an electrical machine to electrical power sources and a load. The invention permits the microturbine to be started using an external DC power source and/or an external AC power source. DC power is converted to AC power by means of a buck-boost chopper, DC bus and a DC-to-AC converter. AC power, from the AC power source, is converted to frequencies and voltages suitable to start a microturbine by a pair of DC-to-AC converters and the DC bus. The frequency and voltage levels of the AC pow...

[ What is claimed is:] [1.]1. A method for operating a turbine coupled to an electric machine comprising: using a DC power source and an AC power source to selectively apply DC power to a DC bus, using a bi-directional converter for converting DC power from the DC bus to AC power such that the frequency of the converted AC power gradually increases, applying the AC power to drive the electric machine to start the turbine; after starting the turbine, using the turbine to drive the electric machine, using the bi-directional converter for converting AC powe...
