hydraulic generator engine governor on 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.

Governor static characteristics

1. Linearity: near line
2. Speed dead-band(measure from main servomotor):

ix≤0.1%( small)
ix≤0.06%(medium)

Governor dynamic characteristics

When governor runs stable under standard manual mode.

1. It should run stably under any kinds of operating status and regulating mode.
2. Servomotor dead-time Tq≤0.2S

​nc. or Dec. time of gate opening

1.Push Inc. Or Dec. pushbutton and hold it, the time of changing 100% gate opening can be adjusted from 2.5 to 60S, it will change gate

opening 0.1% per push.

Change over

1. The variant of gate opening will be less than ±1% of Max. Stroke when change over between AC and DC power.
2. The variant of gate opening will be less than ±1%of Max. Stroke when change over between Auto and Manual running mode.
