Power Conversion System 125kW

FAQs：

• What is the primary function of a 125kW PCS in a BESS?

  The primary function of the PCS is to perform controlled bidirectional AC/DC power conversion between the battery DC bus and the AC electrical system. It regulates the direction and magnitude of active-power transfer during battery charging and discharging.

• How does the PCS interact with the BMS and EMS?

  The PCS operates within the BESS control hierarchy. The BMS supervises battery operating conditions and provides battery-related constraints, while the EMS determines system-level energy dispatch. The PCS executes the corresponding power-conversion commands within its electrical operating limits.

• How is the PCS used during BESS charging and discharging?

  During charging, the PCS converts AC electrical power into controlled DC power for the battery. During discharging, it converts battery-side DC power into controlled AC power for delivery to the grid or connected loads.

• Can the 125kW PCS be used as a building block for a larger BESS?

  Yes. Subject to the specific PCS parallel-operation architecture and system control design, multiple PCS units can be configured as modular power-conversion blocks to achieve higher system power ratings.
