Bidirectional Grid Simulator AC Power Supply

The ANBGS(F) Pro series bidirectional grid simulator AC power source is specially developed for new energy industries such as photovoltaic and wind energy, suitable for solar inverter testing and verification. The solar inverter testing equipment (bidirectional grid simulator) has the function of an 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. 

Support for arbitrary angle abrupt change/crossing test.

Large 10.1-inch color LCD with touchscreen operation.

Comprehensive measurement functions: voltage, current, current peak, frequency, active power, apparent power, power factor, voltage crest factor, etc.

Online monitoring: Monitors IGBT and transformer temperature, fan speed, and input voltage parameters during output mode.

"Black Box" function: Automatically records power status and alarm codes during alarms, significantly reducing maintenance time.

Standard RS-485/Ethernet communication interface and synchronization signal interface, with optional RS232/GPIB communication interface.

Programming: it has universally programmable settings, where voltage, frequency, and phase can be changed according to single-step settings. Trigger phase and cycle count can be set, and parameters of three-phase outputs can be separately configured. Any phase shift/crossing test can be achieved.
