Power System Stabilizers on Generator Exciters

11/15/2015 9:04 AM

Could anyone please help me understand how the PSS on generator exciters damp oscillations? This could have earlier been posted anonymously but that was not intended Regards

Wow, PSS must stand for Post-grad Syllabus Subject.

Did that help, Richard Matsiko......... or do you need the "old cynics" summary?

Yes. Coughanowr and Koppel can. They wrote a book entitled "Process Systems Analysis and Control". Available at technical bookshops.

All reply/post talks about Electrical aspects. The Mechanical aspect is the SPEED of the generator for which the Governor plays a vital role.

In the event of Parallel Operation - the DROOP CHARACTER is very important factor. Generally a droop of 5% and less is considered to be GOOD.

By monitoring the rotation speed at both ends of the turbine generator shaft then inputting the obtained real-time signals into a comparator circuit.

The resultant signal is output to the exciter control and used as a reference to control increase or decrease of the generator exciter voltage.

Increasing excitation presents a higher load on the generator and slows/dampens the rotational speed allowing the generator end of the shaft to match the slower turbine shaft rotational speed.

Decreasing excitation provides the opposite effect allowing the generator shaft to speed up.

These minute induced excitation changes take place at very high speed and are critical to protecting turbine and generator shaft safety and longevity.

For a more in-depth study I recommend you research the GE TVMS Installation & Operations Manual that is available for free online.
