PREVIOUS EXPERIENCE

 

Consultant

(Jan 2012 – Jun 2013)

VeroTech is a Belgium based company with a focus on cutting-edge technologies. It fulfils the short-term needs of its customers by providing specialist knowledge in process improvement and development projects. Punch Powertrain is one of its customers, which is making inroads into the electric and hybrid vehicle transmission system. Despite the recent financial crisis, the company has seen growth in the number of projects it handles and therefore the number of consultants on its payroll.

 

Location: Sint-Truiden, Belgium

 

Team: 3 people with control and development engineering profiles

Highlights

ª          Implemented a real-time simulation tool for the high-speed (13000 rpm) electric motors used in the drive-train of electric and hybrid vehicles. Due to such high speeds and multiple pole-pairs, the sampling time has to be in the order of microseconds to be able to accurately simulate the electromagnetic torque production. This FPGA based tool is used for extensive testing of Motor Control Unit (MCU) software, before it can be deployed in vehicles. It allows the study of the complete operating range and signal faults that may be too dangerous to study even on a test bench.

ª          A detailed manual was written for the implemented simulation platform describing model details, simulation settings and the compilation process.

ª          Improved the simulation speed of the offline motor simulation platform, based on Simulink and SimPowerSystem, by 3 times using the S-function method.

ª          Studied control strategies to reduce the vibration and noise of the Switched Reluctance Machine (SRM) used in electric and hybrid vehicles.

ª          Defined the charging procedure, in accordance with the IEC-61851 standard, for electric vehicles developed by Punch Powertrain. These vehicles are deployed in the Limburg area of Belgium as part of a study concerning the establishment of a smart grid. Instructive documentation was compiled with a summary of the exact requirements to comply with the standard.

PhD Researcher

(Oct 2006 – Oct 2011)

Université Libre de Bruxelles (ULB) in Brussels, Belgium is a public sector university active in research in a variety of disciplines. The BEAMS (Bio- Electro and Mechanical Systems) group is active in the domain of Biomedical, Microtechnology, Electrical Energy and Embedded Electronics. The Electrical Energy group performs research in the area of power systems protection, electromagnetic computations for electrical machines and recently electrical drives for industrial use and power generation.

 

Location: Brussels, Belgium

 

Team: Electrical machines group of 4 persons

Highlights

ª          Modelling and simulation of Wind Turbine Generator Systems (WTGS) in faultless and faulty modes to study control and fault-detection algorithms. In order to study fault-detection algorithms, fault representative models of the plant are required. Short-circuit faults in generator windings are costly and develop rapidly. It is therefore necessary to detect the fault as soon as possible and take appropriate measures.

ª          Experimental study on power-electronic converters for integration of renewable-energy sources into power grids. This work involved defining and carrying out the steps to bring the generating system from cold start upto connection to the grid. The non-ideal behaviour of converters e.g. due to signal delays and dead-time is important here for control performance to avoid large disturbance on the grid as well as the generating system. These non-idealities were ascertained and included in simulation for true correlation between simulation and reality.

ª          Complete design, installation and operation of a WTGS test bench to validate the control and fault-detection methods developed in simulations. The test bench consisted of a wound-rotor induction machine as a generator and a squirrel-cage induction motor to emulate the wind turbine. The generated power is sent to the grid via a back-to-back power-electronic converter.

ª          Project management experience gained through proposal for the funding and acquisition of materials for the WTGS test bench.

ª          Good communication skills with component suppliers.
