HUAQUAN Electricity Engineering Cases
“Photovoltaic + Energy Storage + Generator Set” Hybrid Energy Dispatch System: This project deployed several HQ series 1000 kW intelligent grid-connected diesel generators as peak shaving and supplementary power sources. When the photovoltaic output suddenly drops or there is a demand from the grid dispatch, the power station control system can automatically start the generators, providing stable power within a short period of time.
Off-grid/On-grid Integrated Intelligent Microgrid Solution: This project employs one HQ series 500 kW silent-type automated diesel generator set, which is integrated with a photovoltaic inverter and an energy storage system (purchased separately by the owner). The generator set is equipped with a parallel-grid control system suitable for microgrid control. Working mode one (grid-connected): When the photovoltaic power generation is sufficient, the generator set is in standby mode; when the photovoltaic power is insufficient, the grid supplies power. Working mode two (off-grid / isolated operation): When the power grid is disconnected, the system automatically cuts off the connection with the power grid. HUAQUAN power generator set will immediately start up and work in coordination with the photovoltaic power to supply power to the fish farm loads. The generator set serves as a stable power source, compensating for the randomness of photovoltaic power generation and ensuring the stability of power supply quality (constant voltage and frequency) in the off-grid state. The generator set adopts an anti-corrosion reinforced design and an efficient rainproof and dustproof enclosure, which effectively withstands typhoons and humid climates.
