A hydro-generator is a device that converts the rotating mechanical energy of a hydro-turbine into electrical energy through a main shaft connected to the hydro-turbine runner. According to its structure, it can be divided into: horizontal unit and vertical unit; according to its excitation method, it can be divided into: brushless excitation unit and brushed excitation unit.

<p> Hydro turbine governor is the main controller of the hydro turbine. The governor varies water flow through turbine to control its speed or power output. Generating units speed and system frequency may be adjusted by the governor.</p>

<p> Because of apply to computer monitoring system ,automatic control,protection,measurement,telecontrol and video monitoring,it can communicate with cascade dispatching center to compete telemetering,romote signalling,telecontrol and remote regulating,so that realize unattended operation or on duty with less person and safe economical operation for hydropower station.Systmem is composed of power station control layer and local control protective layer,etc.</p>
