Modellering och hardware-in-the-loopsimulering av kontaktordynamik: Elektronik och hårdvara
Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
The subject of this master thesis is to develop a hardware-in-the-loop simulation environment representing an ABB contactor’s dynamics. A contactor is an electrically controlled mechanical switching device, used where large currents can occur. The hardware-in-the-loop concept means that hardware is connected to computer models simulated in a real-time simulator.In this thesis, the contactor is modeled by dividing it into smaller subsystems. The subsystems correspond to the contactor’s electronics, electromagnetics and mechanical components. The subsystems are mainly realized as computer models. The electronics are also partly realized as hardware, and constitutes the hardware in the setup. The models are implemented in MATLAB and Simulink, and a hardware interface is constructed to connect the hardware part to a real-time simulator from dSPACE. The focus of this report is the modeling of the electronics and the design of the hardware interface. The work was performed in collaboration with another student and his report focuses on the modeling of the electromagnetics and the mechanics as well as software implementations.Measurements are collected from a real contactor and are used to validate the hardware-in-the-loop simulations. The conclusion from the validation is that the simulated contactor behavior corresponds well with a real contactor.
