Virtual Synchronous Generator Uninterruptible Power System

Calsion Medium-Voltage Uninterruptible Power Supply System employs highly reliable synchronous UPS hosts, integrated energy storage devices, transformers, reactors, switchgear, and diesel generator sets to form a complete medium-voltage uninterruptible power solution. In large-scale uninterruptible power applications, medium-voltage UPS systems offer distinct advantages. Deployed at the front end of power supply systems, they simplify infrastructure, reduce investment costs, and enhance power delivery efficiency.

Calsion medium-voltage uninterruptible power systems serve applications requiring large-scale uninterruptible power, including data centers, semiconductor factories, and high-end industrial manufacturing. Equipped with large-scale energy storage batteries, they can also be extended for peak shaving applications, reducing electricity costs.

Operating mode

The main unit adopts a power electronic virtual synchronous generator, with a single-unit power of 2750kVA.

Stand-alone Mode:

During mains power failure, the UPS inverter converts battery power to supply the load.

Power Regulation Mode:

Mains power is filtered through the reactor before supplying the load. The reactor tap charges the UPS battery while the UPS unit simultaneously provides reactive current to the load.

Diesel-Generator Mode:

The diesel generator supplies power to the load after filtering through the reactor, while the reactor tap charges the UPS batteries.

Bypass Mode:

The utility power supply provides power directly to the load without passing through the UPS. The system is configured with both automatic and manual bypass options.
