Power Amplification for Real-Time Power Simulation

Important Note: This data sheet only covers characteristics of the new, low-latency PHIL grid simulation upgrade now available for all SL1200A Series Regenerative AC / Grid Emulators. For full specifications, please see the SL1200A Regenerative AC / Grid Emulator Series data sheet.  As renewable generation, energy storage, electric vehicle charging, and other distributed energy resources (DERs) connect to the grid, engineers need test environments that can reproduce real-time, real-world grid behavior before equipment is deployed. Traditional grid test setups and power amplifiers can be limited in their ability to accurately reproduce dynamic grid conditions at the necessary speeds. Keysight Real-Time PHIL helps engineering teams evaluate complex power scenarios with a Power Hardware-in-the-Loop approach.  Keysight’s Real-Time PHIL solution is designed for engineers who need to test grid-connected equipment against fast-changing, realistic grid conditions. It supports real-time simulation workflows by combining high-power AC / DC output capability, low-latency control, high-speed measurement feedback, and flexible operation modes in one integrated grid emulation platform. The result is a practical way to validate DERs, EV charging systems, energy storage systems, grid-edge controls, and other connected energy technologies before they are exposed to real grid events.  Real-time grid simulation is increasingly important as grid-connected devices become more complex and as control interactions between DERs, inverters, EV chargers, and energy storage systems become harder to validate with static test methods. A low-latency PHIL approach helps engineers close the loop between simulated grid behavior and real power hardware so they can observe how devices respond to dynamic conditions in a controlled lab environment. Keysight’s approach helps reduce the gap between simulation and hardware validation by enabling real power exchange, fast command updates, and high-bandwidth measurement feedback in a scalable SL1200A-based platform.  Regenerative Operation Return absorbed energy back to the facility instead of dissipating it as heat, enabling efficient, long-duration testing of inverters, energy storage systems, EV chargers, and motor drives. True Four-Quadrant Operation Seamlessly source and absorb power to support realistic evaluation of bidirectional technologies, including battery systems, V2G equipment, regenerative drives, and grid-support functions. AC and DC Capability Validate AC grids, DC buses, batteries, and hybrid power architectures using a common platform, reducing test setup complexity and maximizing lab flexibility.  Keysight Real-Time PHIL adds low-latency Power Hardware-in-the-Loop capability to the long list of capabilities of the SL1200A Series Regenerative AC / Grid Emulator platform. With ≤ 21 µs actuation and measurement delay, high-speed real-time interface support, scalable AC / DC power capability, and high-fidelity dynamic response, the solution helps engineers validate complex grid behavior fast and with greater confidence. At the same time, remaining a versatile AC / grid and DC instrument.  Supplemental characteristics are not warranted but are descriptions of performance determined either by design or by type testing. Supplemental characteristics are typical unless otherwise noted and apply at the DUT in compliance to the specified load line length, with local sensing.  If you already own an SL1200A Regenerative AC / Grid Emulator please contact your local Keysight representative to inquire about on-site upgrade services for your specific model. If you do not yet own an SL1200A, please refer to the SL1200A Series data sheet to choose the model that meets your grid simulation / power amplification needs.
