| Abstract | ||||
| This paper describes, the application of transient energy function and some laws of theoretical mechanics necessary to the problem of analysing Co-ordinated stabilizer in a multimachine power system. The co-ordinated stabilizing inputs for the exciter and governer loops to improve transient stability in the power system are defined. The different energies in the power system are analysed. If the power system is asymptotically stable in the first swing cycle, the rate of change of total transient energy must tend to zero. This constraint is accomplised by the proposed stabilizer. The stabilizer is designed on the base of balancing its forces with the necessary forces to damp swings of generator rotors. The effectiveness of the proposed stabilizer is demonstrated by applying it to a generating station in a 10-generator and 19-bus power system, which represents the reduced Egyptian Unified Network. | ||||
