Cinergia GE/EL+ vAC/DC Regenerative Converter

The versatile Cinergia GE/EL+ vAC/DC Regenerative Converter combines all Cinergia models in one unit. A 4 quadrant AC Grid Emulator and AC regenerative load in combination with a bi-directional DC power supply and regenerative DC load. This makes the unit widely applicable in many applications. This includes battery testing, battery characterization, battery emulation, PV panel simulation and testing of solar inverters.

The simulation of smart grids and micro grids and the testing of bi-directional inverters are on the rise to support the electricity grid. The built-in amplifier also makes the unit suitable for Power Hardware In the Loop (PHIL) testing. In summary, a high-performance machine that feels at home in all terrains.

The Cinergia GE/EL+ vAC/DC is available in 13 models with powers from 7.5kW to 160kW. This can be expanded to >2MW by connecting multiple units in parallel.

AC MODE

With the Cinergia GE/EL+ vAC/DC in AC mode it is possible to switch the full power in both single phase and three phase. All parameters (amplitude, phase, frequency, etc.) of each phase can be set individually and can therefore be controlled independently of each other. The extensive harmonic generator makes it possible to program up to 50 harmonics (2500Hz) per phase in amplitude and phase. In addition, 20 freely selectable sub- and inter-harmonics per phase are possible. Complex test sequences can be self-configured including dips, spikes, flicker and frequency variations. Tests according to certain standards such as IEC 61000-4-11/ 13/ 14/ 18, IEC 1668 and SEMI F47 are available in sequence. But certain production test sequences are of course also possible. The sequences are stored internally and run independently of PC communication.

Acting as an electronic AC load, the required active and reactive power can be set per phase. Full inductive or capacitive loading is also possible. To serve as an RLC load, resistance (0.8 to 1000Ohm), inductance (0.1 to 2000mH) and capacitance (0 to 3.7mF) are adjustable. This is particularly important for the new standards surrounding anti-islanding testing.

DC MODE

Thanks to the unique multi-channel design, the power of the Cinergia GE/EL+ vAC/DC in DC mode can also be distributed over one or three bi-directional channels. Each channel can be individually set and controlled in CV, CC, CR or CP mode, as well as the alarm and safety limit settings. The maximum output voltage is 750Vdc as standard, but in DC mode it is also possible to connect two units in series. The combination of series and parallel connection means you have the full power of both units available over a voltage range from 250Vdc to 1500Vdc (depending on the model). It is also possible to build and execute automatic sequences in DC mode.

CONTROLS AND SOFTWARE

The Cinergia GE/EL+ vAC/DC is equipped with an intuitive User Interface, which can be operated with the built-in 4.3 inch touchscreen or with the PC software. The unit can be controlled with Modbus or Labview via the LAN connection. Optionally, extensive software is available for Battery Emulation, Batterypack Testing and PV panel Emulation.
