Resistive-Inductive Load Bank for Grid-Scale Energy Storage Converter Testing

With the rapid development of new power systems, testing standards for PCS converters, grid-tied inverters and microgrid controllers keep upgrading. A pure resistive load bank can only simulate resistive load and cannot reproduce inductive grid conditions. The integrated resistive-inductive load bank meets high-precision testing demands for grid-connected energy storage equipment.

1000kW load bank

This resistive-inductive load bank allows separate adjustment of active and reactive power, simulating loads like motors and transformers. It supports LVRT, islanding protection, grid synchronization, reactive power support and harmonic tests required by international grid codes. Energy storage manufacturers, third-party test labs and power grid research institutes rely on this load bank to recreate complex grid conditions and verify the stability and protection logic of PCS.

A simple resistive load bank ignores reactive power and causes deviation between lab test and real grid operation, which may trigger false protection or grid-connection failure on site. Our resistive-inductive load bank uses modular resistor and inductor units. Active and reactive power can be adjusted smoothly with wide power factor range, fast response and high sampling precision to capture transient voltage and current curves.

This load bank is matched with dedicated test software to run automatic test sequences and generate official certification reports. Dry-type cabinet design eliminates liquid leakage risk with low noise for long-term lab operation. As a direct manufacturer, we customize power, voltage and adjustment steps according to test schemes and local grid standards. The high-precision resistive-inductive load bank is core equipment for PCS R&D and grid certification, helping energy storage companies obtain approvals and safely connect to global power grids.
