Power Generation Unit and Station Control

For gas and steam turbines used in power generation, S&C’s control solutions include additional features:

• Manual speed control capability
• Protective override for overspeed and critical speed
• Automatic start-up and shutdown sequencing
• Precise extraction control
• Load control for synchronizing multiple generators
• Power droop (active power control), characterized valve droop (position control), and isochronous (frequency control) modes

Station control solutions for power generation provide two critical forms of control:

• Active Power/Frequency Control (P/F) limits active power grid exchange, ensures proportional load (MW) sharing among generators, and controls frequency in islanded conditions.
• Reactive Power/Voltage Control (Q/V) regulates bus bar voltage, ensures proportional reactive power (MVAR) sharing among generators and transformers, and limits reactive power exchange with the grid.
