FAQ
Q1: What is the key difference between this and a standard programmable AC source?
A: This unit offers true four-quadrant (bi-directional) power flow, meaning it can both supply power like a source AND absorb power like a load. This is essential for testing inverters that feed power back into the grid. Standard AC sources can only supply power.
Q2: Can it test for anti-islanding protection as per UL 1741?
A: Yes. It can be programmed to simulate the precise impedance changes and test profiles required for anti-islanding protection (non-islanding and intentional islanding) tests outlined in UL 1741 and similar standards.
Q3: Is it suitable for Hardware-in-the-Loop (HIL) testing?
A: Absolutely. With its fast digital control, real-time communication interfaces (like Ethernet), and optional RTDS compatibility, it is an ideal power amplifier for HIL test benches simulating complex grid environments.
Q4: What power level do I need for testing a 100kW inverter?
A: You would typically need an AC Power Unit rated higher than 100kVA. A 120kVA or 150kVA unit is recommended to provide sufficient headroom for over-current tests, reactive power testing, and to account for efficiency losses.
Q5: How is this unit different from a "grid emulator"?
A: They are functionally the same in this context. "AC Power Unit for Renewable Energy Testing" and "Grid Simulator/Emulator" are often used interchangeably. This product is specifically optimized and characterized for the rigorous demands of renewable energy and power electronics testing.
