Abstract Given the complex problem of transmission line failure and outage difficulty predicting rate time with certainty, accident prediction information is provided for power grid managers. This paper proposes a three-order fundamental Fourier function fault model based on monthly scale. method does not rely any strict assumptions driven by real data in province. The fitting results reflect b...

The transmission lines are exposed to the atmosphere nature and will be affected by adverse weather such as lightning storm, so that it will affect the reliability of transmission system. This paper studies the fault probability model of transmission line during the lightning storm, and evaluates the short-term reliability of transmission system in the forecasting weather condition. Firstly, bu...

Abstract With the continuous progress of power grid digitization, Building Information Model (building information modeling, BIM) technology can no longer meet application display requirements engineering. Power model (grid model, GIM) uses parameterization to build a 3D which reduces redundancy and is conducive digital transfer project. This paper briefly analyzes structure GIM data model. It ...

Via structures in multi-layer printed circuit boards (PCBs) and packages are studied using an equivalent transmission line model. Thus, transmission line theories, such as characteristic impedance and propagation constant, can be used to characterize the performance of via structures in a signal path. The closed-form expressions of R, L, G, C parameters of the equivalent transmission line model...
