Generator Control Panel 400V Synchronizing Unit for Hydro Turbine Plant

400V Generator Control Panel for Hydro Plants

This panel covers generator synchronizing, protection and excitation control in one cabinet for 400V hydro generating units. It is built to the single line diagram of the station, factory wired and function tested before shipment, and supplied with the wiring diagram and test record.

Selling Points

• Synchronizing built in. Automatic synchronizer with check sync relay, voltage and speed matching, and manual backup for black start conditions.
• Protection relay package. Over and under voltage, over current, reverse power, over speed and earth fault protection with event recording.
• Excitation control. AVR interface or built in excitation control with over excitation and loss of excitation protection.
• PLC based logic. Sequence logic for start up, synchronizing, load transfer and shutdown, with touch screen or push button operation.

Product Parameters

Supply Scope

• Generator control and synchronizing cabinet
• Protection relay and metering set
• Excitation control interface
• Wiring diagram, test record and parameter list
• Spare fuse and relay set

Station Data Required

• Generator rating, voltage and current
• Single line diagram of the plant

• Required protection functions and communication protocol

Why This Unit

A single coordinated panel removes the interface gaps between synchronizer, protection and excitation, which are a common cause of commissioning delay on refurbished stations. Factory function testing and the as built wiring diagram make later fault finding on site straightforward.

Packing and Delivery

The unit is protected with rust preventive coating, fixed on a steel skid or packed in a seaworthy wooden case. Electrical parts are packed in moisture proof bags. Site drawings, test reports and the operation manual are supplied with the shipment.
