Non-Standard Inverse Characteristic Curve Modeling of Digital Overcurrent Relay with Lagrange Interpolation Methode

Modeling of a Novel Fuzzy Based Overcurrent Relay Using Simulink

In modern protection system the key challenge is the trade-off between the security demand (no false tripping), the speed of operations and the dependability requirements. To meet this challenge properly, the application of a novel Artificial Intelligence (AI) method, using fuzzy logic, in power system protection has been proposed in this paper along with the simulated data. The examined techni...

Providing A New Characteristic for Overcurrent Relays

This with the integration of distributed generation (DG) to meshed distribution systems, the operating time of the protective system becomes a major concern in order to avoid nuisance DG tripping. This paper proposes a new tripping characteristic for directional overcurrent relays (DOCRs) that can achieve a higher possible reduction of overall relays operating time in meshed distribution networ...

Inverse Definite Overcurrent Relay Discrimination Algorithm and Its Application in Industrial Power Systems

In a normal electrical network, it is crucial to design a system complete with protection to prevent any abnormalities or fault occurrence to disturb the whole source of electrical to be shut down. Only a portion of effected area should be closed and fault duration at high current value should be closely monitored. Overcurrent protection device discrimination play vital roles to ensure protecti...

Lagrange Two-Dimensional Interpolation Method for Modeling Nanoparticle Formation During RESS Process

On Multivariate Lagrange Interpolation

Lagrange interpolation by polynomials in several variables is studied through a finite difference approach. We establish an interpolation formula analogous to that of Newton and a remainder formula, both of them in terms of finite differences. We prove that the finite difference admits an integral representation involving simplex spline functions. In particular, this provides a remainder formul...
