A Test Platform to Evaluate Electro-Mechanical Interaction in Aircraft Generator Systems

There is a growing trend to consolidate what are traditionally pneumatic, hydraulic, and electrical systems into a single electrical power system. This simplifies engine structure and may lead to improvements in efficiency as well as reduced
maintenance schedules, however, it places greater demands on the gas turbine-generator system which supplies the electrical network. Electro-mechanical interaction occurring within the electro-mechanical system may lead to a reduced lifespan of key mechanical components and electrical network instability. This paper describes the design of a variable speed test platform to represent an aircraft gas turbine-generator system and presents practical results which demonstrate the effect of electromechanical interaction.
