The ANBGL(F) series Feedback AC Source Load combines the functions of both a grid simulation source and an AC load simulator, meeting a wide range of testing requirements in the new energy industry. Source Mode is designed to comprehensively simulate grid characteristics, specifically developed for the photovoltaic, energy storage, and other new energy industries. It is suitable for grid adaptability testing of equipment connected to the grid, capable of providing stable voltage and frequency outputs, as well as supplying environments with various power quality characteristics such as voltage variations, frequency variations, harmonics, interharmonics, imbalance, flicker, etc., according to relevant standard requirements. Load Mode offers multiple operating modes, including CC/CR/CP/CS/RLC, capable of simulating RLC, resistive, and switching loads. Compared with traditional passive loads, this unit integrates both AC source and load functions in one, with regenerative energy feedback to the grid. This significantly reduces customers' procurement costs and energy consumption, while aligning with the demands of a low-carbon society.
Built-in multiple RLC network models with adjustable parameters for simulating linear load characteristics.
Capable of simulating non-linear load characteristics.
Output voltage slew rate > 1V/μs, capable of realistically simulating 1ms grid interruption tests.
Support paralleling of up to 8 or more identical models for system expansion, with performance and accuracy comparable to a standalone.
Support 2nd to 50th harmonic superposition, interharmonics from 1 to 3,000Hz, and programmable waveform customization (sine, triangular, and user-defined waveforms).
