Gas turbine engines are normally provided with speed reduction units when used as prime movers for electrical power generating sets. These speed reduction units have many undesirable features such as vibration, noise, frictional losses, added maintenance and high cost. The desirability of eliminating such units becomes apparent particularly when related to the continued increase in the use of gas turbines in electrical generating sets. A task was therefore initiated to investigate the feasibility of coupling a gas turbine directly to an electrical generator. This not only results in a more compact system, but also provides a means of generating high-frequency power. With static frequency-conversion equipment, a single, highly transportable electrical generating system would be available for applications requiring multiple sources of electrical power having different voltage and frequency characteristics. The results of an equipment survey and a literature search conducted by the Laboratory are presented, together with discussions on potential advantages, disadvantages, and problems or difficulties anticipated in the procurement and utilization of high-speed high-frequency power equipment.
