TC.ACS with "Regenerative RLC-Load Mode"
REGATRON TC.ACS Series Grid Simulators now offer a brand-new operation mode: The RLC-Impedance Simulation Mode !
By this, the behaviour of one to three phase reactive circuits can be simulated in real-time within a bandwidth from DC up to 1000 Hz. TC.ACS therefore is able to replace bulky and expensive lumped components like power resistors, power capacitors and high power magnetics. Setting and tuning of simulated component values is possible in full operation by a specialized TC.ACS GUI, which allows even for programmable and automated test sequences.
RLC-Load Mode Application Example: New methods for Anti-Islanding Tests for Grid-tied Power Generator Equipment
The standards DIN V VDE V 0126-1-1 or VDE-AR-N 4105 or IEEE 1547 provide strict regulations for power generating equipment feeding the public grid. The main aim is to harmonize all important technical specifications and to prevent safety risks at “islanding” conditions. Up to now test methods using passive tuned circuits require a considerable effort both in terms of expensive components as also of work time. Power circuit simulation by REGATRON TC.ACS series allows for replacing lumped component R-L-C-circuits simply by “Simulated Impedance”. Furthermore the same TC.ACS device can be used to perform all necessary voltage and frequency tests based on the same test circuit, therefore the complete range of test requirements according to standard DIN V VDE V 0126-1-1 is being met with a fraction of expenditures both in time as in material.
