Regeling van de Turbineregelaar

Turbine-generator units in power systems store kinetic energy due to their rotation, which is released when the load increases.

The electrical torque of each unit increases to meet the increased load, while mechanical torque remains constant, causing a drop in rotor speed and frequency.

This imbalance is corrected through governor action, which adjusts mechanical output power based on frequency changes.

The steady-state frequency-power relationship for turbine-governor control involves changes in frequency, turbine mechanical power output, reference power setting, and the regulation constant, typically 0.05 per unit.

Load changes cause the rotor to accelerate or decelerate, creating transient frequency disturbances, but under normal conditions, the rotor stabilizes at a new steady state.

Summing the frequency-power relation for each turbine-generator unit determines the system's steady-state frequency response.

Wind turbines control power output by adjusting the blade pitch angle, a process modeled in pitch control systems, particularly for Type 3 and 4 turbines.
