ANBGS(F) Series Bidirection Grid Simulation AC Power Supply

ANBGS(F) Series Bidirection Grid Simulation AC Power Supply

    ANBGS(F) series analog power supply which can feed back to the grid is specially developed for new energy industries such as photovoltaic and wind energy, suitable for testing and verification of inverters.

Product Introduction

The ANBGS(F) series energy regenerative type grid simulation power is specially developed for new energy industries such as photovoltaic and wind energy, suitable for inverter testing and verification. The power supply has the function of energy regenerative type grid and can operate in four quadrants, saving energy consumption with low operating costs; FPGA digital control technology is adopted for smart inverter test process; with sine wave output and multi harmonic superposition output, single-phase, two-phase or three-phase High/Low (zero) Voltage Ride-Through (H/LVRT), which can simulate various abnormal conditions of power grid, and cooperate to achieve test of over/under-voltage, over/under-frequency, unbalance and anti-islanding protection, meeting test requirements in relevant regulations.

Applications

  • HVRT/LVRT: Programmed output mode for photovoltaic industries, to simulate the process of grid voltage sags and recovery and can simulate multiple modes such as zero voltage ride through (ZVRT), low voltage ride through (LVRT), high voltage ride through (HVRT), and Combined HVRT/LVRT etc., and the voltage, holding time, ride through angle, recovery voltage etc. can be set.
  • Unbalance: setting of U/V/W phase and voltage individually, direct setting of unbalance.


  • Sag: An output mode simulating short-time changes to voltage, 1ms Zero Voltage Ride-Through test.

  • Programming: General programmable settings, voltage/frequency/phase are transformed by single-step setting, setting of trigger phase and cycle times, setting of parameters separately for three-phase output, sag/ride-through test in any phase.

  • Harmonic: Harmonic editing (2-50th), various harmonics of various orders superposed on standard sine wave, setting of component and angle of each harmonic. The single harmonic can reach 30%, unlimited total harmonic content and harmonic superposition times. 50 sets of harmonic storage groups for fast calling.

  • Interharmonics: Interharmonic editing, interharmonics superposed on standard sine waves, setting of interharmonic trigger angle, frequency, component and scanning time; frequency of interharmonic: 16-2500Hz.

  • Flicker: Simulate the flicker characteristics of power grid to conduct the flicker adaptability test of DUT.

  • Large-size color LCD, numeric key input, knob operation
  • PC control software
