TC.ACS Series

TC.ACS is a series of full digital, full 4 quadrant 3-phase AC power sources with exceptional programming features. Each TC.ACS unit represents a three-in-one configuration:

• Versatile synthesized 3-phase grid simulator with 4 fully controlled active outputs. Operation mode setting per comprehensive software tools. Note the fully active N-connection available at the Simulator Port.
• Built-in full 4-Quadrant 1 to 3-phase power amplifier with outstanding qualities, 3 independent and galvanic isolated amplifier inputs, especially suited for high bandwidth HIL applications within the power laboratory, assisted by an external RT processor.
• Programmable RLC-load mode (electronic AC load with grid recuperation) to substitute real and bulky resistors, inductors and capacitors. Reactive power is recuperated into the 3-phase grid with maximum efficiency.

Applications
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 recuperation operation and vice versa
• Analyses of energy flow

Hardware
The modular structure based on 30 kVA or 50 kVA units allows for a flexible adaptation to the customer's power requirements. By simply connecting basic units in a parallel mode, systems of up to 1000kVA can be set up. The hardware is operating in all 4 quadrants and is able to fully refeed into the power system. Apart from testing power feedback units, the system also enables the operation of linear and nonlinear feeding systems for measuring and evaluation purposes. An operation in single phase mode is also possible down to DC mode.

User Software ACSControl
The tailor made software tool ACSControl enables the operator either to manually operate the system or to program and run automated test sequences and to use the functionality of data acquisition of the system. Moreover the software offers some screens for parameterising, sequencing, visualising of the current system data and test results as well as for recording and documentation of test results. ACSControl allows also for switching over between the 'Simulator Mode' and the 'Amplifier mode' of the system.
