Do you regularly test multiple power devices of different sizes? Perhaps you’re looking to expand your power system to accommodate higher energy demands? Then a new update for our EAC-ACS-4Q four quadrant grid emulators could be the perfect solution.
It is now possible to connect EAC-ACS-4Q four quadrant system models with different nominal powers in an asymmetric parallel configuration. For example, two 30kVA units and a 50kVA unit can be connected together in master/slave to create a 110kVA system. Previously, achieving the same output required either four 30kVA units (120kVA) or three 50kVA modules (150kVA).
The enhancement is ideal for projects where budgets may be constrained. The capability can also be retro-enabled on existing modules with a firmware update.
A high-speed communication bus controls all slave modules via a master unit. This enables consistent dynamics and bandwidth regardless of the number of modules operating in parallel. For higher power requirements, parallel configurations enable outputs exceeding 2.5MVA.
About the EAC-ACS-4Q
The EAC-ACS-4Q is a modular grid emulator with full 4 quadrant operation. Modules can sink and source both AC and DC power. All three of the unit's phases are individually programmable for voltage, frequency, phase angles, and superimposed harmonics. Optional current control is also available.
This product is widely used for single and three-phase motor testing, AC transformer evaluation, grid simulation, grid-tied inverter analysis, and aerospace electronics trials. It also supports Power Hardware-in-the-Loop (P-HIL) simulations and EMC testing solutions.
Each unit comes with an isolated analogue, Ethernet and USB interface as standard. A CANmp interface is also available, operating up to 1kHz. Up to 100 messages are user configurable. Along with the CAN ID the data length code, byte order, start bit, data type and signal factor can be adjusted by the user.
GUIs are available for grid emulation (with Fourier tool), RLC load simulation with 12 different topologies and EMC compliance testing.
On request your chosen modules can be fitted into a lab rack or flight case. Multiple modules can be fitted into the same enclosure. Lockable castors are available for mobile operation. Having a programmable power system mounted into a flight case or lab rack on castors is often advantageous, especially when several departments or test cells share the same equipment.
