6 FAQs about [Air outlet from steam end and excitation end of generator]

What type of excitation system is a generator?

Exciter systems can be rotating or static. Rotating includes brushless and brushed types and static includes compound sources and potential sources. A generator has a prime mover like a turbine or diesel generator. The excitation system creates the electromagnetic field in the rotor.

How do excitation systems work?

Modern excitation systems are static where DC current is created by rectifying AC power using saturable current transformers (SCTs) and power potential transformers (PPTs). A source is required to create excitation before it can be self-sustained from the generator.

What is a static excitation system?

No matter your footprint, power supply or generator output, Siemens Energy can offer the right excitation system for any application in any power plant. Static excitation systems (SES) employ the most advanced technology for synchronous generators and synchronous condensers, and are compatible with generators from any manufacturer.

What is the role of excitation system in synchronous generator?

The excitation system plays a major role in ensuring the reliable continuous operation of synchronous generators, since it significantly influences the operational readiness and dynamics of the generator. Moreover, it controls the reactive power response of the synchronous machine.

What is a static excitation system (SES)?

Static excitation systems (SES) employ the most advanced technology for synchronous generators and synchronous condensers, and are compatible with generators from any manufacturer. SES are suitable for low to high performance classes, from 1 to over 1200 MVA generator output, mainly in hydroelectric, gas, steam and nuclear power plants.

Which static excitation system is suitable for a high performance generator?

THYRIPOL®-S static excitation system is suitable for low to high performance classes from 150 to approx. 1600 amps generator output mainly in hydroelectric, gas, steam and nuclear power plants and are characterized by absolute reliability and maximum efficiency.
