Power system output feedback stabilizer design via optimal subeigenstructure assignment
- Dept. of Electrical Engineering, National Taiwan Univ., P.O. Box 23-72, Taipei (TW)
This paper addresses a design of power system stabilizer using an optimal reduced order model whose state variables are torque angles and speeds. System damping can be improved by using eigenvalues assignment, and the coordination of stabilizers can be achieved through eigenvector assignment by maintaining system mode shapes. The proportional-integral PSS{sub s} will be derived by the optimal reduced order model instead of the whole system model. The effectiveness of this stabilizer is evaluated and this study reveals that by using the output feedback only, the result of eigenstructure assignment is more stable and much better than the assignment method based on the whole system model. Examples, one machine to infinite bus system and a multimachine system are given to illustrate the advantages and effectiveness of the proposed approach. Results based on the whole system model are included for comparative analyses.
