What is a Generator Governor?
A Generator Governor is a control mechanism that adjusts the generator’s input to maintain a constant speed, ensuring the power output matches the load demand. This is crucial for power system stability, especially during load changes.
Key Functions of a Governor:-
Speed Regulation: Controls fuel supply to keep generator speed consistent, vital for grid synchronization.
Load Sharing: Distributes load evenly among multiple generators to prevent overloading and optimize performance.
Frequency Control: Maintains system frequency within acceptable limits, ensuring stable and reliable power supply.
What is an Exciter?
An Exciter supplies the necessary field current to the rotor winding of a generator. It controls the magnetic field to regulate the generator’s voltage and reactive power output.
Key Functions of an Exciter:
Voltage Regulation: Keeps the generator’s terminal voltage within desired limits by adjusting the field current.
Reactive Power Control: Balances reactive power, ensuring optimal power factor and system stability.
System Stability: Enhances dynamic stability by responding quickly to load changes and disturbances.
Improved Efficiency: Optimizes generator performance, leading to more efficient power generation and reduced costs.
