Synchronization and Reactive Power Control
... work together to enable stable and efficient operation of interconnected power systems as generation sources and loads change dynamically.
Image for illustration purposes.
Synchronization in power systems refers to the process of matching the voltage, frequency and phase angle of a generator or power source to the existing grid before connecting them. This is critical for safely integrating new sources into the grid.
Reactive power control is important for maintaining voltage stability and power quality in AC power systems. It involves managing the balance between real and reactive power to optimize power flow and minimize losses.
Key aspects of reactive power control include:
– Using devices like capacitor banks, reactors, and static VAR compensators to provide or supply reactive power as needed
– Adjusting generator excitation to control reactive power output
– Coordinating transformer tap changers to regulate voltage
– Implementing voltage/VAR optimization schemes
Proper reactive power management helps:
– Maintain voltage levels within acceptable ranges
– Improve power factor
– Reduce transmission losses
– Increase power transfer capability
– Enhance overall system stability
