Description
Summary:In this paper, improving in transient stability is made through a development of new approach. Since the maximum use of existing capacities along with the increased powers transferred through the transition lines make transient stability studies even more important. Generator tripping is one of the most effective methods that remedy to stability in case of severe faults. In this method, a number of units of a certain unit are disconnected as a way of making the system works steadily. The braking resistor is less efficient than generator tripping for transient stability. In the proposed method, system stability against severe turbulence is tackled with minimum tripping of generator units. At this proposal, the intensity of fault will be valuably lessen by applying braking resistor, and then, for the purpose of improving transient stability, the kinetic energy is reduced by removing certain unit at the right time. The approach has been tested on 9-bus with 3-generator system to demonstrate promising effects.
