Feedback Grid Simulation Power Supply ANBGS

The ANBGS 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. The power supply features 100% energy feedback to the grid, and can operate in four quadrants, energy-saving and low cost; FPGA digital control, intelligent inverter test process; sine wave output and multi-harmonics superposition output, single-phase, two-phase or three-phase low (zero) voltage ride through (LVRT), which can fully simulate various abnormal conditions of the grid, to cooperate with over-voltage/under-voltage, over-frequency/under-frequency, unbalance and anti-islanding protection tests to meet test requirements of relevant regulations. Features: 1.Adopt FPGA digital technology, realize intelligent inverter testing process; 2.High performance low (zero) voltage ride through; 3.Voltage and frequency can be set as complex programming such as Step, stage or varations, overvoltage/undervoltage, over-frequency/under-frequency test; 4.Harmonic mode, can be superimposed 2 to 40-th harmonics; 5.Three-phase Unbalanced mode, adjustable three-phase voltage and three-phase phase difference, Realize three-phase Unbalanced test; 6.High voltage DC output. Loop test combining PV inverter; 7.Operating in over current shock( up to 3 times of rated current) within 2s,strong load capacity; 8.Complete measurement function: voltage, current, peak current, frequency, active power, apparent power, power factor, voltage crest factor; 9.Online monitoring: IGBT temperature, transformer temperature, fan speed, input voltage and other parameters in output state; 10.Operating data recorder: Automatically record the power status, alarm code etc. in case of alarm, greatly reducing maintenance time; 11.Automatic fan speed adjustment according to the temperature of the power supply, quiet; 12.Lock key, user-friendly design, automatically locking after no-operation for 5 minutes to prevent misuse; 13. Combination cabinet, 8" large-screen color LCD; 14.Standard RS232, optional RS485, GPIB, Ethernet port or analog control mode; Applications: 1.Grid Simulator Power Supply, the solar cell simulator and power analyzer forming the inverter test system. 2.Low (zero) voltage ride through 3.Harmonic mode
