Abnormal sound of energy storage button

Are battery energy storage systems causing noise?

Battery Energy Storage Systems (BESS) are relatively new to the US, and communities are only just starting to become aware of the noise issues they can create. BESS’s are generally large power storage facilities, often comprised of hundreds of battery units the size of shipping containers spread over many acres of land.

Did NMS conduct a noise study for a new battery energy storage facility?

In July, 2022, NMS was retained to conduct a detailed noise study for a new Battery Energy Storage Facility near Los Angeles (for confidentiality purposes, no identifying client or site information is included in this article). The facility consisted of over 300 batteries, over 60 PCS units and two transformers covering about 6 acres of land.

What are the causes of abnormal sound of current transformer?

The cause of abnormal sound of current transformer (1) The screws fixing the mutual inductor are loose and should be tightened. (2) Internal core piercing bolts of the transformer are loose. (3) The small capacity of the transformer results in magnetic saturation when the transformer is overloaded.

Can broadband PCs intake & vent noise mask battery fan tone?

Balancing noise emissions of equipment to mask the battery fan tone. Our noise measurements and modelling revealed that the tone produced by the battery fans could be effectively masked by the broadband PCS intake and vent noise so long as this source was not reduced in level too much.

How does a PCs air intake acoustically absorbent foam work?

Installation of acoustically absorbent foam lining the inside PCS air intake cavities. This material was installed to reduce the buildup of sound inside the cavity and further lower the noise escaping through the intake. Balancing noise emissions of equipment to mask the battery fan tone.

What is a battery energy storage system?

Batteries: Rechargeable battery units are the core of the Battery Energy Storage System. Battery units (often 20 ft. in length and 8 ft in width and height) include cooling systems to maintain optimal operating temperature. The cooling systems use fans and condensing units which can generate noise levels up to 92 dBA at 1 m from the equipment.
