The Nordex Group is investing in a new power hardware-in-the-loop (PHIL) test bench for grid compliance testing of power electric drivetrains. The test bench includes a grid emulator, allowing Nordex to simulate a wide range of grid conditions, including voltage and frequency variations, power fluctuations, weak grid conditions, and grid faults, without the need for field testing.
The power HIL test bench is developed and engineered by R&D Test Systems. The increasing complexity of grid integration drives Nordex's investment in the power HIL test bench. As renewable energy penetration increases, grid codes with different requirements are established worldwide, and the requirements are becoming stricter. Additionally, weakened grids and possible future off-grid scenarios for hydrogen production add to the complexity of grid integration. The power HIL test bench complies with the new Technical Specification IEC 61400-21-4 for test bench-based compliance testing. R&D Test Systems will deliver the power HIL test bench to Nordex in 2024.
