LARGEHYDRO AUTOMATION & CONTROL

The controls, the start and stop sequences, the human-machine interface, the turbine governor and voltage regulator as well as the electrical and mechanical protection systems are included in this package.

Methodology

• global study, functional analysis, electrical schematics
• design of the protection systems (redundant or by loss of voltage)
• simulation of the turbine dynamics and the governor system with Matlab
• software programming on Schneider or Siemens PLC’s
• turbine regulating modes : opening, speed, power, frequency, level and flow control
• voltage regulating modes : reactive power control power factor control with limiters PQ, stator current, over and under voltage and V/Hz
• electrical protection functions : overcurrent, thermal, asymmetry, over/under voltage, over/under frequency
• commissioning using procedures and check lists ensuring the safety of the facility and individuals
