High-Frequency Power Generation and Distribution in Multi-Megawatt Power Systems

A model of an autonomous power system that generates and distributes power at 240 Hz was developed at the University of Texas Center for Electromechanics. This high-frequency ac power system (HFAC) includes several gas turbine-generator units, two propulsion power trains, several power distribution and conversion units, a supercapacitor energy storage module, a high-power pulse load, and multiple service loads. In the paper, “High-frequency power generation and distribution in multi-megawatt power systems,” coauthored by Joe Beno, Bob Hebner, and Hamid Ouroua and presented at the 2011 IEEE Electric Ship Technologies Symposium (ESTS), April 10-13, 2011 in Arlington, Virginia, four case studies were considered. These were: partial loss of generation, application of a large step load, power restoration to a vital load, and operation of energy storage. Preliminary analysis showed that the power system remained under control during the four events. Some benefits of the HFAC architecture are highlighted in the paper, followed by analysis results of the case studies.
