The GSZ Series is Regenerative Grid Simulator with an optional load and PHIL interface capability. This comprehensive grid simulator is designed for the testing and verification of all grid-tied applications. Simulate any grid condition and test to global regulatory compliance standards such as IEEE 1547, UL 1741, IEC 61000-3, IEC 61000-4, and more. The GSZ series’ high power density provides 30kVA/kW up to 55kVA/kW in a single cabinet and can parallel up to 550kVA/kW.
This comprehensive platform is optimized for PHIL, has three powerful DSPs to cover advanced applications, and eliminates the need for add-on equipment. Simulate almost any power disturbance and distorted waveforms. Regenerative power allows sourcing and sinking of current up to 100% of rated power.
The GSZ Regenerative Grid Simulator supports both low and high voltage ranges for AC or DC. Test accurately with seamless transition of voltage ranges. The constant power voltage range for both higher current at lower voltage and higher voltages at lower currents eliminating the need to switch between voltage ranges. This prevents potential disruptions in output power.
For real-time Power Hardware in the Loop (HIL) simulation applications, the GSZ Grid Simulator offers a high speed set of analog inputs and outputs with fast output response. This analog interface provides high speed input for controlling frequency, voltage or current and waveshape. Voltage and Current output capture signals are returned to the Real Time Simulation System.
The Regenerative Grid Simulator – GSZ Series has a built-in waveform digitizer and scope with fast transient capabilities at 200us time resolution supporting LIST, PULSE and STEP modes. Waveform generation includes ten Standard, Sine, Square, Triangle, Clipped and Harmonics AND inter-harmonics generation.
The increasing development of grid-connected devices requires accurate compliance testing to meet regulatory standards such as IEEE 1547 and UL 1741. Regenerative grid simulators are ideal for simulating voltage sags, brownouts, and other real-world disturbances.
In this webinar, you’ll learn how smart control, flexibility, and advanced hardware performance can provide significant advantages for testing pre-compliance, LVRT, interoperability, harmonics and flicker, immunity, anti-islanding, and more.
Simultaneous AC and DC operation of modes per phase(or channel), and the automatic switching of output modes provides test engineers with a unique capability and the highest degree of flexibility. AC, DC output configurations are available in single, split, three phase and multi-channels with optional isolated neutrals in AC and DC.
