Automated testing of Medium Voltage Drive Hardware in Loop systems

ABB Medium Voltage (MV) drives offer flexible and reliable modular design for single as well as multi motor applications with power range from 3 to 36 MW. In order to validate the complex converter topologies and control methodologies of MV drives, a powerful multi core real time simulator is used for Hardware in Loop (HiL) testing. The Medium Voltage Drive Hardware-in-Loop (MVDHiL) system is preferred over traditional analogue test or field test as it offers flexibility, cost benefits and no high voltage risks. This paper describes about the MVDHiL set up for ABB ACS1000 Drive and discuses manual and automated testing of MVDHiL with lab results.
