High Speed Turbo-Generator: Test Stand Simulator Including Turbine Engine Emulator
Abstract
Our research developed: a reference model of a turbo-generator system, a control model of the high speed generator test stand, and a model of a high speed generator test stand (including controls) that uses an electric machine to drive the generator as though it were being driven by the gas turbine engine. The performance of our gas turbine model was compared to that predicted by a validated commercial gas turbine simulation software and the two agreed well for operation near the design point. Agreement was less good when operating off the design point, for reasons that are well understood and are attributed to simplifications in our model. A model-based controller schema was adopted to control the synchronous motor so that it emulates the torque-speed characteristics of the gas turbine engine. Excellent agreement was found when comparing the performance of the reference system to the performance of the gas turbine emulator system when both were subjected to changes of the electrical load on the generator.
