Hydro Turbine Governor PLC Speed Governor For Water Turbine
This series of PLC governor are suitable to various medium and small turbine generator sets. It is produced according to standards of GB/T9652.1-1997.
This governor designed upon advanced hydraulic technology and PLC control technology, achieve the hydro turbine automatic regulation and control.
Function: Regulate the turbine speed, Adjust the frequency of generator set, track the frequency of power supply network and control phase. Safety protection in case of emergent stop.
This PLC governor have two series: GYT Type which control the reaction turbine, like francis , Kaplan etc.
CJWT type can control the impulse turbine, such pelton turbine, turgo turbine.
This PLC governor used to regulate and control the hydro turbine speed, steady the generator frequency at 50HZ or 60HZ.
The governor can operate in full automatic control or manual field/ remote control.
The microcomputer governor use PLC. Use the technology of directly measurement the unit and net frequency by PLC, to raise the reliability of governor greatly.
The GYT series programmable microcomputer governor has the main functions as follows:Realize the starting-up,stopping, synchronization of unit in auto/manual mode, the regulation of unit load and emergency shut down etc.
The unit trace the frequency of network automatically before synchronization, and it can make the unit frequency achieve the synchronous requirement rapidly. If the network frequency has fault, it will switch to the frequency setting for starting-up automatically.
