摘要
建立了计及输电线路暂态能量的网络暂态能量函数。分析支路暂态能量的变化规律 ,从系统动态的角度研究支路暂态能量变化对系统暂态稳定性及网络参数和运行参数的影响。指出所有支路中分担暂态能量最大的支路或割集是对系统暂态稳定性影响最为关键的输电环节 ,系统的暂态稳定性取决于该环节的强壮程度。
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.
