Power Electronic Modelling and Emulation of an Electrostatic Precipitator

In this paper a power electronic emulation of an electrostatic precipitator is presented. Precipitator power supplies can be tested under real power and operating conditions up to 200 kVA. Energy consumption of the system is very low, because the energy which is drawn by the emulation converter is fed back into the power grid. Therefore, just the power losses have to be provided by the grid. It is possible to implement different precipitator models to verify real plant operation conditions or to optimize parameters for new precipitator designs. Precipitator power supplies can be tested as well in static as in dynamic operation points to verify the proper function of the device in the laboratory.
