【Abstract】 The network energy function describing the total OMIB power system transient energy is developed. At the givenunstable mode, the effect of variation of branch transient energy on OMIB system stability. network parameters andoperation parameters. is studied. It is concluded that the branch or cut set which is allocated the maximum transient energyhas critical effect on system transient stability. Simulation results show that the analysis is correct.更多还原
