Resumo: | This master’s thesis presents the development of an electric traction system for urban vehicles using controller hardware-in-the-loop (CHIL) simulation and focusing on the electrical system components. For the purpose of obtaining a simulation model, the traction system is modeled following the forward facing methodology and the vehicle longitudinal model is used to represent the vehicle dynamics. The studied system comprises a single traction motor in a longitudinal architecture applied to the Renault Twizy vehicle, which is a passenger car. The main components of the traction system are designed following the latest trends, with a supply voltage of 400 V and the inverter switching at 10 kHz. The traction machine is a permanent magnet synchronous motor (PMSM) with a rated power of 11 kW, similar to the traction system of the previously mentioned vehicle model. Based on this, a field oriented control method is proposed to achieve speed regulation with a flux-weakening technique switching in when the demanded voltage is higher than the voltage supplied to the inverter. In order to develop realtime simulations, a OP5700 simulator manufactured by OPAL-RT Technologies is used, which is available at the Instituto Nacional de Ciência e Tecnologia em Geração Distribuída de Energia Elétrica (INCT-GD), benefiting from toolboxes that allow the representation of high frequency events with high accuracy. Moreover, an interface board was designed to connect the simulator to a digital signal processor (DSP) where the control system is programmed. The simulation results validate the designed traction system and the proposed real-time simulation approach. The presented work aims to establish a base of knowledge for the development of a power hardware-in-the-loop (PHIL) simulation platform of electric traction systems, which would be an alternative to implementing prototypes of these systems using only physical components. |
