Analysis and Evaluation of the Influence of Transmission Direction Changes on System Reliability in Distribution Networks
With the continuous growth of energy demand and the expansion of power system scale,the change of transmission direction of distribution network has become one of the important factors affecting system reliability.Through in-depth analysis of the mechanism of transmission direction change,this paper reveals its basic principle,its relationship with power grid stability and its influence mechanism on system parameters such as frequency and voltage.On this basis,the influence of system reliability is analyzed,including reliability evaluation index and method,the influence of transmission direction change on system availability and the influence on system Mean Time Between Failure(MTBF).Aiming at the problems found,a series of optimization strategies and measures are put forward to improve the reliability and stability of distribution network.
