Description

In static excitation systems, the power rectifier directly supplies the field winding of the synchronous machine. There is no pilot exciter. A static excitation system is terminal-fed (also called bus-fed) when the supply is taken from the machine itself through a power potential transformer (PPT).

Specification

Static excitation systems are not inherently self-exciting, so they require an external supply to jump-start the excitation process and build up sufficient magnetic flux. This process is called field flashing. Static excitation systems provide a number of benefits that make them an attractive option for synchronous machine control:

• Simple, reliable and cost-effective design.
• Minimal maintenance requirements.
• High performance and fast response characteristics.
