Abstract:
1. A substation of a long distance, megawatt power transmission and distribution network, comprising: a) a single phase isolating high frequency high kilovolt transformer having at least one input primary winding coupled through a circuit breaker to a long distance, megawatt power distribution line and at least one output secondary winding; b) an input solid state high frequency high kilovolt switching network comprising a plurality of semiconductor switching devices, the input switching network defining at least one input node for receiving an input power waveform from the transmission network and at least one output node connected to the at least one primary winding of the transformer; c) at least one output solid state high frequency high kilovolt switching network comprising a plurality of semiconductor switching devices, the output switching network being connected to the at least one secondary winding of the transformer and defining at least one output node from which an output power waveform is taken from the substation; and d) control means for controlling the switching devices of the input and output switching networks to generate the output power waveform at the at least one output node from the input power waveform applied to the at least one input node.
