Self-tuning stabiliser for a multimachine power system

The application of an adaptive pole-shifting self-tuning power system stabiliser (SPSS) to a mulit-machine power system is described. Results presented in the paper show that this adaptive stabiliser performs better than a conventional unit. It is easy to implement because only the locally available measurements are used. Studies also show that there is no conflict between the proposed SPSS and other kinds of power system stabilisers on the system.
