The functionality of electronic loads and load simulator usually overlap with each other and in the context of programmable power testing the two terminologies are usually interchangeably used.
But when it comes to certain testing applications where complex testing scenarios are required or that regulations and standards enforce a specific testing sequences, one should take attention to the differences that a simply programmable electronic load as a test bench might not be sufficient.
Here in the following context, the use case and introduction focus on the testing application of advanced load simulators and especially for scenarios where MW and MVA power rating is required.
MVA AC Load Simulators are equivalent to advanced grid simulators with weak grid emulation capability for complex grid-forming capability testing where power profile and pattern of flow, as well as electrical characteristics, are far beyond being complex but also intertwined.
AC Load Simulators at MVW power rating should be functionally competent to replicate the below advanced testing applications and use cases:
Accurately replicate complex current-drawing characteristics of modern devices like EV chargers and VFDs.
Harmonic Injection & High Crest Factor: Utilize programmable harmonic synthesis (up to the 50th order) to emulate highly distorted waveforms, evaluating EUT stability under severe Total Harmonic Distortion (THD).
Unbalanced & Asymmetrical Loading: Leverage independent three-phase control to simulate severe phase imbalances or phase loss, testing the transient regulation and robustness of microgrids and backup power systems.
Utilize real-time control algorithms for stepless, high-precision emulation of any RLC combination.
Anti-Islanding Compliance: Achieve millisecond-level RLC tuning to accurately pinpoint grid resonance points, verifying swift anti-islanding protection per IEEE 1547, UL 1741, and IEC standards.
Extreme Power Factor Stress: Emulate extreme power factors (±0.3 to 1.0, leading/lagging) to validate the reactive power compensation and load-bearing stability of grid-tied systems.
Emulate harsh, real-world conditions of distributed grids featuring low short-circuit capacity and volatile voltage.
Impedance Regulation (SCR & X/R): Customize Short-Circuit Ratios (SCR) and X/R ratios to simulate high grid impedance, validating PLL stability and mitigating Sub-Synchronous Oscillation (SSO) risks.
Transient Fault Simulation: Execute LVRT/HVRT (ride-throughs), ROCOF, and phase angle jumps to evaluate the virtual inertia response and grid recovery assistance capabilities of MW-level renewable equipment.
DC load simulators go far beyond basic electronic loads that merely draw current from a source. Instead, they feature highly dynamic electrical characteristics and complex, user-configured stepped and sequenced profiles to accurately replicate the behavior of real-world power systems.
ActionPower’s cabinet architecture is built upon multiple independent load modules designed for redundancy and incremental scalability. Beyond module-level expansion, cabinets can be paralleled to form higher-capacity load systems, allowing users to flexibly scale and reconfigure their power absorption testing infrastructure according to evolving test requirements.
