The WHES 135-225kW Power Conversion System (PCS) is a high-performance, intelligent power conversion unit designed as the core component for modern commercial, industrial, and utility-scale energy storage systems. It serves as the critical interface between the battery storage system and the electrical grid, efficiently managing the bidirectional flow of energy.
Engineered for maximum performance, the PCS utilizes an advanced three-level topology that achieves an exceptional conversion efficiency of up to 99%, minimizing energy losses and optimizing the overall system's economic return. It is designed to support 1500Vdc battery systems, a standard that enhances system efficiency, reduces cabling costs, and is essential for large-scale deployments.
The system features intelligent cluster-level control, enabling precise management and capacity coordination across multiple units for large, complex installations. It supports full four-quadrant operation, providing fast and independent control of both active and reactive power. This allows for rapid response to grid signals, making it ideal for applications like frequency regulation, voltage support, and power factor correction.
Flexibility and robustness are key design principles. Its modular design simplifies installation, maintenance, and potential future expansion. The PCS demonstrates strong grid adaptability with built-in High Voltage Ride-Through (HVRT) and Low Voltage Ride-Through (LVRT) capabilities, ensuring stable operation and grid compliance during voltage disturbances, which is crucial for reliable integration with renewable energy sources.
