Abstract
The objective of this research is to develop an advanced Electric Motor Drive System (EMDS) for high-speed electric trains. Currently, most of the electric drive systems for high-speed trains are limited to 600 km/h. However, the need for a transportation system with higher speed, higher efficiency, and more reliability is pushing the market toward more advanced solutions. Hyperloop technology is considered as a new concept for the modern transportation era to transport people and freight at very high speeds (over 1000 km/h) which propels levitated vehicles inside low-pressure tubes. New, advanced propulsion systems are a key enabler for high-speed train and Hyperloop technology.
In this thesis, an advanced EMDS is developed for the Hyperloop application. To do this, first, a list of the requirements for the EMDS is defined. Based on the requirements for the motor, a topology is selected. A co-simulation optimization procedure based on the finite element method (FEM) is proposed. Key parameters of the machine are chosen as variables to optimize the machine design objectives. The co-simulation tool then is used to run a sensitivity study and an optimization of the objective functions. Subsequent to motor development, an advanced control algorithm is developed to ensure that the EMDS is stable and operates smoothly and efficiently. Due to the complexity of the EMDS in this application, a real-time simulator is needed to model and simulate the entire system. Extensive off-line and real-time simulations are carried out to evaluate the proposed EMDS performance for a typical high-speed train under various operating conditions.
