LG Digital Water Turbine Governor 220V AC DC Smart Control

digital hydraulic speed governor for hydro turbine generator

Based on Automation products, Smart Control* Turbine Speed Governors can regulate any type of turbine with any power output. They integrate seamlessly into the Smart Control Distributed Control System. Only one engineering tool is therefore needed, helping simplify software management, licensing, upgrades and training. 

They feature compact and modular plug-and-play hardware for easy installation and maintenance. Intuitive software, with advanced functions derived from more than 20 years of Hongya power’s hydro experience, enhances turbine processes, helping refine plant operation and reduce machine wear.

The Smart Control* Governor’s features for specific turbine types include blade discretizer for Bulb and Kaplan turbines, individual wicket gate control for Pump turbines and a jet dispatcher for Pelton turbines. With simplex or redundant configurations and a rugged design, SmartControl* Governor can operate in harsh conditions with electromagnetic interference, vibration, humidity and oil.
