خلاصه مقاله:

A simple and systematic proceduer for decentralized stabilizer design for multimachine systems is presented in this paper.
The procedure first selects most effective location of a stabilizer according to a machine stability index. The parameters of the stabilizer are then determined by a decentralized feedback control scheme. This process is carried out for one stabilizer at a time The resultant overall improvement of the system stability, measured by a system stability index is used to decide how many stabilizers are required for system. The preposed techeique is illustrated by a test system. Both eigenvalue analysis and nonlinear simulation are performed to investigate the effectiveness of the technique.
