A New Scheme for Damping Torsional Modes in a Series Compensated Power System
نویسنده
چکیده
In the present paper, a new scheme for damping torsional modes in a series compensated power system has been developed. The proposed scheme, utilizes the effectiveness of combined active power and frequency (C.A.P.F.) SVS auxiliary controller in co-ordination with an induction machine damping unit coupled to the T-G shaft. Studies are conducted on the first IEEE benchmark model. The damping scheme stabilizes all the torsional modes over a wide operating range of power transfer. SVS is installed at the middle of transmission line to optimize the power transfer capability. Also the optimal location of IMDU along the T-G shaft has been determined by using eigenvalue analysis. It is found that locating IMDU after the IP turbine yields the maximum damping effect.
