ActionPower India's grid simulators replicate real-world grid distortions and weak grid conditions in coordination with your EUTs for validating their interoperability and interconnection compliance.
NEXUS is a next-generation modular, bidirectional AC power supply and grid simulator designed for the rigorous testing of grid-tied inverters, electric vehicles, and renewable energy systems. NEXUS features a fault-tolerant redundant architecture and advanced regenerative technology that efficiently returns absorbed energy back to the facility grid.
The CORTEX AC is an advanced programmable AC power source and regenerative grid simulator engineered for comprehensive compliance testing of renewable energy systems and EV charging infrastructure. It delivers exceptional waveform precision and dynamic control, allowing users to accurately replicate complex grid anomalies and extreme operating conditions.
Ultimate high-power from a single integrated cabinet - defined exclusively by ActionPower as the tower-type programmable power supply. TITAN provides compatibility between high-power and performance, further with scalability of up to 10 MVA to match utility-scale power rating testing applications.
Built-in pre-compliace testing sequences for one-click automation setup in compliance with IEEE 1547, UL 1741 & IEC series, user-defined distortion and weak grid conditions through SCR and X/R settings, integrated islanding test mode and RLC modelling... all within ActionPower 2020.
Voltage sags and swells represent sudden reductions or increases in grid voltage, often caused by faults or large load switching. ActionPower’s grid simulators allow you to recreate these conditions to test how inverters and other on-grid devices respond to under-voltage and over-voltage events per standards like IEC 61000-4-11.
Simulating slow frequency drift or abrupt step changes enables testing of devices' frequency tracking capabilities and ride-through performance. This is essential for compliance with grid codes such as IEEE 1547, particularly under weak grid conditions or high renewable penetration.
Unbalanced voltages between phases can occur due to asymmetrical loads or faults in the grid. Our AC grid simulation systems replicate unbalance scenarios to test the impact on three-phase equipment, especially in PV inverters and energy storage systems.
Phase angle shifts can result from synchronization issues or switching events. ActionPower’s grid simulators support precise control of phase angle displacement, helping verify inverter synchronization behavior and response during grid reconfiguration or transition events.
Modern grids often contain harmonic distortion due to nonlinear loads. Our systems simulate individual or grouped harmonic components up to the 50th order, including interharmonics, allowing full-spectrum EMC and power quality compliance testing per IEC 61000-4-13.
Sudden disconnection (grid loss) followed by reclosure represents a critical test condition for grid-tied systems. ActionPower’s grid emulator simulates both clean and disturbed reconnection events to evaluate protection, synchronization, and ride-through behavior.
By injecting fault conditions such as Line-to-Ground (L-G), Line-to-Line (L-L), or three-phase faults (L-L-G), you can validate fault ride-through (FRT) response and system protection behavior in accordance with utility interconnection requirements.
ActionPower enables precise setup of islanding scenarios by decoupling the grid while adjusting load/generation balance. This is crucial for testing anti-islanding protection mechanisms (passive and active) in PV inverters per UL 1741 and IEC 62116.
To verify the stability of grid-tied inverters in remote or weak grid areas, ActionPower simulators provide advanced grid impedance modeling. By adjusting the Short Circuit Ratio (SCR) and X/R ratio, users can simulate low-strength grids to evaluate control loop stability and oscillation risks.
With built-in programmable waveform libraries and pre-defined test sequences based on global standards (IEEE, IEC, GB), our simulators help automate complex test routines. Users can also define custom waveforms to recreate specific grid anomalies observed in the field.
