DEIF The GPU-3 Hydro is well-suited for PLC-controlled systems

Application

The Generator Protection Unit (GPU-3 Hydro) is a compact microprocessor-based 

protection unit containing all necessary functions for protection of a hydro turbine

driven synchronous/asynchronous generator. It contains all necessary

galvanically separated 3-phase measuring circuits.

The GPU-3 Hydro is well-suited for PLC-controlled systems, and the interfacing can

be done via digital and analogue I/Os or via serial communication.

Display unit

The display unit is separate and can be installed directly on the main unit or in the

front of the switchboard door (3 m display cable included). Up to two additional

displays can be installed within 200 m. The display unit shows all measured and

calculated values as well as alarms and data from the event log.

Self-test

The GPU-3 Hydro automatically carries out a cyclical self-test at start-up.

If any errors are found, they will be displayed in clear text in the display and 

indicated with a relay output (status output).

M-Logic (Micro PLC)

This configuration tool is part of the PC utility software which is free of charge.

With this tool, it is possible to customise the application to your needs.

It is possible to dedicate specific functions or logical conditions to different inputs and outputs.

Setup®

Setup is easily done via a menu structure in the display (password-protected) or

via the USB PC connection and the Multiline 2 Windows-based PC utility software.

The utility software offers additional features such as monitoring of all relevant information

during commissioning, saving and downloading of settings and downloading of software updates.

Synchronisation

As an option, the GPU-3 Hydro can perform synchronisation of the generator.

After closing of the breaker the regulation is switched OFF, and the GPU-3 Hydro

will carry out all necessary protective functions.

Options

In order to perfectly match the product solution to specific applications, the functionality

of the GPU-3 Hydro can be equipped with a number of available options.

The options selected by the customer will be integrated in the standard GPU-3 Hydro,

hereby securing the same user interface unaffected by whether the application

needs a highly complex or a more basic genset controller.

Refer to the paragraph "Available options" for the options available.
