Highlights

PHIL-Based Automated Anti-Islanding Test Solution

As distributed energy resources (DERs) proliferate, ensuring grid stability and safety becomes increasingly critical. Validating the inverter's anti-islanding features and algorithms is vital to ensuring safe operation and compliance with grid codes.

Anti-islanding testing has traditionally been a time-consuming, equipment-intensive process, including manual tuning of a load bank containing resistors, inductors, and capacitors (RLC). The Keysight SL1221A automates anti-islanding testing using real-time simulation and power hardware integration. This approach reduces manual effort, improves repeatability, and accelerates time to certification.

  • Automated anti-islanding testing aligned with IEEE 1547.1-2020 / UL 1741 SB standards
  • Patent-pending resonant RLC autotuning eliminates manual tuning and reduces test time
  • PHIL-based real-time simulation ensures reliable and fast testing
  • Compact, integrated test setup reduces lab space and energy consumption
  • Seamless software integration with KS8400B PathWave Test Automation for streamlined workflows and reporting
