Amplifier Mode for PHIL with Low Latency

The 9510 is externally controllable via a low latency, per-phase analog input. This feature amplifies control signals from real-time simulation systems for Power Hardware In the Loop (PHIL) testing. The dual range output ensures the maximum flexibility and accuracy in PHIL simulations.

LVRT & Area Electrical Power System Disturbance Simulation

The 9510 Grid Simulator can directly simulate common power line disturbances, such as Low Voltage Ride-Through (LVRT) test patterns, through a combination of macros and user-definable wave shapes. Macros are pre-programmed sequences of settings where which entered through a menu driven interface, downloaded to the grid simulator, and are executed to provide precise control of the output(s). This method is used to generate LVRT test patterns, sub-cycle, and multi-cycle changes to the output covering nearly every need.

Example Waveforms

Simulate a wide range of waveforms including LVRT patterns, transient anomalies, voltage harmonics, or any other irregularity which can be drawn as a single cycle.
