Control Panel For Micro Hydro Power Plant

AUTOMATIC VOLTAGE REGULATION

The controller is fully digital and combines high performance with easy programming and maximum flexibility. As a plant integrator, we provide customers with either a complete solution or specific components to adapt to their specific for updating and enhancing performance.

Hongya hydro power more than 30 years of know-how and proven experience in manufacturing, commissioning, and maintenance of generator excitation systems and is ISO 9001:2000 certified.

MAXIMUM FLEXIBILITY FOR THE HIGHEST PERFORMANCE

Proven excitation technology that is also applied to combustion and steam generators, allowing the standardization of spare parts, training, and services across your fleet.

A single engineering tool for commissioning and maintenance

Modular configuration

Suitable for any hydro application, from simplex to full twin redundancy configurations.

Integrates supervision and protection of power electronics

Seamless integration with existing control systems as stand-alone equipment.

Main characteristics:
* Double microprocessor adjusting channel with redundancy each other, indepandent manual channel can also be added as well.
