Intelligent Air Cooling On Grid Controller
The GREEF ENERGY Hydro Grid-tied Converter integrates multiple advanced functions into a single system. It performs AC-to-DC rectification for Permanent Magnet generators, DC-to-AC inversion, and includes a sophisticated energy management system. Featuring a configurable dual LCD touchscreen, the device offers user-friendly operation and adaptability to various needs.
Utilizing advanced converter technology, the system dynamically controls output power in real-time by monitoring turbine rotational speed. This enables precise regulation of voltage and frequency, essential for stable operation of Permanent Magnet Synchronous Generators (PMSGs), ensuring optimal performance and reliability.
The converter includes intelligent water gate control with integrated sensors for water level, flow, and pressure, creating a comprehensive safety framework. This system continuously monitors critical parameters to ensure secure and stable operation.
For seamless grid integration, the converter supports direct grid-tied operation, enabling grid charging and energy feedback capabilities. This allows the system to draw power when needed and feed excess energy back to the grid, enhancing overall energy efficiency.
