DIVE-Plant Control Including Torque Control

The DIVE-Plant Control is an up do date control system of a speed-variable hydro power plant for a system-parallel operating hydro power plant according to the parallel operating regulations of the German electricity association (VDEW).

The DIVE-Plant Control Comprises the Following Functions:

Automatic operation start of the turbine after power failure
Automatic operation starts and stops according to the water level
Automatic speed variation / torque control according to the changing discharge and head
Grid monitoring
Fault monitoring and logging
Monitoring of the hydraulic aggregate

Automatic Shut-Down (Emergency Shut-Down) of the Turbine:

Monitoring of mains contactor signals
Monitoring temperature limits
Currentasymmetry of generator
Monitoring of inverter signals

Monitoring System for the Whole Hydro Power Plant:

The monitoring system comprises the main measuring systems to realise a fully automatic operation and is designed to ensure a durable and failure-free operation of the whole power plant.

Monitoring and logging of all relevant signals
Fault- and confirmation report
Direct and live data connection to the DIVE-Service of the Fella Maschinenbau GmbH
Generator protection (Voltage, Current, frequency)
Cos φ-control (cosφ →1, adjustable) no need of a reactive power compensation system.
Grid synchronisation

Monitoring System for the Hydro Power Turbine:

Monitoring electrical power output
Monitoring temperatures generator (PT100- thermometer / redundant)
Monitoring temperatures bearings (PT100-thermometer / redundant)
Monitoring water level inside the “DIVE-Turbine”
Monitoring water level before and after inlet rack
Monitoring operation start procedure

Water-Level Control:

Digital controller integrated in SPS
Water-level sensor (pressure sensor)
