Regatron TopCon TC.ACS Full 4-quadrant grid simulators, ‘HIL mode’ 4-quadrant voltage amplifier, Programmable RLC load mode

Introducing the Regatron TopCon TC.ACS Full 4-quadrant grid simulators, ‘HIL mode’ 4-quadrant voltage amplifier, Programmable RLC load mode

REGATRON’s  3-in-1 full 4-Quadrant, Regenerative, Bidirectional Source & Sink Grid Simulators (Grid Simulator, Power Amplifier and AC load)‎ of the series TC.ACS are of a precisely engineered, high quality, modular design.

The latest multi-level inverter technology for high-resolution voltage / current patterns, allows the Simulator  to cover the entire fundamental frequency range from DC up to 1000 Hz and up to 5000 Hz modulation bandwidth. A specialized multi-processor core prepares all relevant voltage / current shapes in real-time to ensure a very stable phase relationship and event timing throughout.

Key Features

Programmable testing parameters

The multi-level inverter technology common with a remarkable high switching frequency opens up the way to a wide base frequency range from DC up to 1000Hz and an exceptionally high modulation bandwidth of 5 kHz. Therefore, harmonic distortion up to the 100th harmonic @ 50 Hz or the 83th harmonic @ 60Hz can be exactly reproduced, assisted by a comfortable Fourier tool. Of course, the system can easily and comprehensively be adapted to the various tasks to be carried out within the fields of R+D, laboratory, end-of-line testing and education. By means of the application software ACSControl, the user is enabled to program the following parameters:

• variation of basic system voltages and frequency
• settings of phase relationship
• voltage drops in the whole network or individual drops per phase
• micro ruptures and flickers
• over- and under voltages
• voltage asymmetries
• superimposed harmonic and interharmonic voltage waveforms
• variation of phase angles
• special conditions for EMC testing
• transition from feeding to refeeding operation and vice versa
• analyses of energy flow

Key Benefits

Application example: TC.ACS as an element of a Test Lab equipment

Comprehensive testing equipment for solar inverters, among others, integrates not only the grid simulation but also an additional simulation system for photovoltaic cells. The programmable TopCon Quadro DC power supplies together with the optional TC.LIN postprocessors in combination with the software tool SASControl form a finely graduated modular PV simulation environment. By using this testing equipment a PV inverter device can be comprehensively tested regarding the photovoltaic issue as well as in terms of the grid feed-in aspect.
