6 FAQs about [Auxiliary power supply equipment for energy storage power stations]

What is auxiliary power supply system?

The auxiliary power supply system provides an advanced multi-voltage power supply for all systems during normal and autonomous operation of the station. The auxiliary power supply system is designed to supply the protection automation and auxiliary equipment at both 110/15 kV (110/20 kV) and 400/220/110/15 kV distribution stations.

What is auxiliary power?

This power may be provided by other units in operation during startup or may be dedicated to specific equipment, such as boilers, pumps, fans, temperature controls, and other peripheral devices. The purpose of auxiliary power is to ensure that critical systems and devices have the necessary power to function properly.

Who is responsible for auxiliary power supply?

When an external auxiliary power supply is required, project owners or their EPC (engineering, procurement and construction) contractors are typically responsible for designing, furnishing and installing the auxiliary power supply circuit. This includes auxiliary power transformers, switchboards and cables.

What is auxiliary power / grid power?

Auxiliary power or grid power is used to supply the peripheral devices initially to prepare the fuel cell stack ready to supply power to demands. Air pump is running 100% for 15 sec to blow off any possible water accumulation in the cathode circuit.

What is the rated voltage of auxiliary power supply?

For example, the rated voltage of the auxiliary power supply might be 400V, 480V, or 208V. The circuit must also be sized based on the peak auxiliary load of the selected BESS product and the specific project configuration. Each BESS product has a unique auxiliary load design and peak auxiliary load.

What are the requirements for auxiliary power supply circuits?

The auxiliary power supply circuit must be designed to meet the BESS product's technical requirements, which vary by product. For example, the rated voltage of the auxiliary power supply might be 400V, 480V, or 208V. The circuit must also be sized based on the peak auxiliary load of the selected BESS product and the specific project configuration.
