Real-time emulation for power equipment development. Part 2: The virtual machine

摘要: For pt.I see ibid., vol.145, no.2, p.92-7 (1998). Power electronic control of electromechanical systems has become common. These employ components which switch at high frequency and have very complex interactions. The load they supply is often intricate in itself difficult (or impossible) to create an experimental environment. It would be advantageous replace the electromechanics with a solid-state equivalent can flexibly programmed emulate real system. paper concerned describing this idea, illustrating concept by emulating electric motor its associated mechanical load. phrase 'virtual machine' been coined describe gives/takes power from converter match as closely possible electrical machine virtual effectively dynamically controllable source/sink capable providing bidirectional level interface converter. Using machine, tested diverse applications under wide variety loading conditions without need for any electromechanics. Test results show that close agreement between possible. limits imposed practical implementation are also examined.
